+
+Known bugs:
+
+* The overflow/underflow exceptions may be badly handled in some functions;
+  specially when the intermediary internal results have exponent which
+  exceeds the hardware limit (2^30 for a 32 bits CPU, and 2^62 for a 64 bits
+  CPU) or the exact result is close to an overflow/underflow threshold.
+
+* Under Linux/x86 with the traditional FPU, some functions do not work
+  if the FPU rounding precision has been changed to single (this is a
+  bad practice and should be useless, but one never knows what other
+  software will do).
+
+* Some functions do not use MPFR_SAVE_EXPO_* macros, thus do not behave
+  correctly in a reduced exponent range.
+
+* Function hypot gives incorrect result when on the one hand the difference
+  between parameters' exponents is near 2*MPFR_EMAX_MAX and on the other hand
+  the output precision or the precision of the parameter with greatest
+  absolute value is greater than 2*MPFR_EMAX_MAX-4.
+
+Potential bugs:
+
+* Possible incorrect results due to internal underflow, which can lead to
+  a huge loss of accuracy while the error analysis doesn't take that into
+  account. If the underflow occurs at the last function call (just before
+  the MPFR_CAN_ROUND), the result should be correct (or MPFR gets into an
+  infinite loop). TODO: check the code and the error analysis.
+
+* Possible integer overflows on some machines.
+
+* Possible bugs with huge precisions (> 2^30).
+
+* Possible bugs if the chosen exponent range does not allow to represent
+  the range [1/16, 16].
+
+* Possible infinite loop in some functions for particular cases: when
+  the exact result is an exactly representable number or the middle of
+  consecutive two such numbers. However for non-algebraic functions, it is
+  believed that no such case exists, except the well-known cases like cos(0)=1,
+  exp(0)=1, and so on, and the x^y function when y is an integer or y=1/2^k.
+
+* The mpfr_set_ld function may be quite slow if the long double type has an
+  exponent of more than 15 bits.
+
+* mpfr_set_d may give wrong results on some non-IEEE architectures.
+
+* Error analysis for some functions may be incorrect (out-of-date due
+  to modifications in the code?).
+
+* Possible use of non-portable feature (pre-C99) of the integer division
+  with negative result.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+		   GNU LESSER GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+  This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+  0. Additional Definitions. 
+
+  As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+  "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+  An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+  A "Combined Work" is a work produced by combining or linking an
+Application with the Library.  The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+  The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+  The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+  1. Exception to Section 3 of the GNU GPL.
+
+  You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+  2. Conveying Modified Versions.
+
+  If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+   a) under this License, provided that you make a good faith effort to
+   ensure that, in the event an Application does not supply the
+   function or data, the facility still operates, and performs
+   whatever part of its purpose remains meaningful, or
+
+   b) under the GNU GPL, with none of the additional permissions of
+   this License applicable to that copy.
+
+  3. Object Code Incorporating Material from Library Header Files.
+
+  The object code form of an Application may incorporate material from
+a header file that is part of the Library.  You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+   a) Give prominent notice with each copy of the object code that the
+   Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the object code with a copy of the GNU GPL and this license
+   document.
+
+  4. Combined Works.
+
+  You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+   a) Give prominent notice with each copy of the Combined Work that
+   the Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the Combined Work with a copy of the GNU GPL and this license
+   document.
+
+   c) For a Combined Work that displays copyright notices during
+   execution, include the copyright notice for the Library among
+   these notices, as well as a reference directing the user to the
+   copies of the GNU GPL and this license document.
+
+   d) Do one of the following:
+
+       0) Convey the Minimal Corresponding Source under the terms of this
+       License, and the Corresponding Application Code in a form
+       suitable for, and under terms that permit, the user to
+       recombine or relink the Application with a modified version of
+       the Linked Version to produce a modified Combined Work, in the
+       manner specified by section 6 of the GNU GPL for conveying
+       Corresponding Source.
+
+       1) Use a suitable shared library mechanism for linking with the
+       Library.  A suitable mechanism is one that (a) uses at run time
+       a copy of the Library already present on the user's computer
+       system, and (b) will operate properly with a modified version
+       of the Library that is interface-compatible with the Linked
+       Version. 
+
+   e) Provide Installation Information, but only if you would otherwise
+   be required to provide such information under section 6 of the
+   GNU GPL, and only to the extent that such information is
+   necessary to install and execute a modified version of the
+   Combined Work produced by recombining or relinking the
+   Application with a modified version of the Linked Version. (If
+   you use option 4d0, the Installation Information must accompany
+   the Minimal Corresponding Source and Corresponding Application
+   Code. If you use option 4d1, you must provide the Installation
+   Information in the manner specified by section 6 of the GNU GPL
+   for conveying Corresponding Source.)
+
+  5. Combined Libraries.
+
+  You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+   a) Accompany the combined library with a copy of the same work based
+   on the Library, uncombined with any other library facilities,
+   conveyed under the terms of this License.
+
+   b) Give prominent notice with the combined library that part of it
+   is a work based on the Library, and explaining where to find the
+   accompanying uncombined form of the same work.
+
+  6. Revised Versions of the GNU Lesser General Public License.
+
+  The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+  Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+  If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.

+arctan(x)  took 0.560332 ms (2047 eval in 1147 ms)
+
+and now we get:
+
+[zimmerma@coing tests]$ ./timings-mpfr 1000
+Using MPFR-3.1.0-dev with GMP-5.0.2
+[precision is 3322 bits]

+x/y        took 0.006989 ms (262143 eval in 1832 ms)
+sqrt(x)    took 0.007084 ms (262143 eval in 1857 ms)
+exp(x)     took 0.292063 ms (4095 eval in 1196 ms)
+log(x)     took 0.246886 ms (4095 eval in 1011 ms)

+mpfr_div (log, sin, cos, arccos, arctan).

+Fixed constants pi and log(2) computation when logging is used: When
+MPFR is built with logging support, these two constants are used by
+the logging functions (via mpfr_fprintf, then mpfr_log, for the base
+conversion). Since the mpfr_cache function isn't re-entrant when
+working on the same cache, we need to define two caches for each
+constant. Otherwise the constants could be incorrect; for instance,
+"MPFR_LOG_ALL=1 ./tconst_pi" was failing.
+Note: the bug was introduced with the new logging system from r7575
+for MPFR 3.1.0, based on mpfr_fprintf instead of mpfr_out_str (which
+doesn't depend on mpfr_log).

+[src/gmp_op.c] Added function mpfr_muldiv_z (currently static -- should
+it be in the API?) that computes y = RND(x*n/d), where n and d are mpz
+integers. Changed mpfr_mul_q and mpfr_div_q to use this function.
+Note: the code of the general case is currently the same as the old
+mpfr_mul_q/mpfr_div_q code, thus needs to be fixed.

+Added tools/ck-version-info Perl script with the same license as
+Makefile.am, to check consistency concerning -version-info and
+that the -version-info value is up-to-date.
+Updated Makefile.am:
+  * In dist-hook, replaced complex sh code by a call to ck-version-info.
+  * Distribute ck-version-info (EXTRA_DIST).

+Source reorganization. In short:
+  * Added directories and moved related files into them:
+      - src for the MPFR source files (to build the library).
+      - doc for documentation files (except INSTALL, README...).
+      - tools for various tools (scripts) and mbench.
+      - tune for tuneup-related source files.
+      - other for other source files (not distributed in tarballs).
+    Existing directories:
+      - tests for the source files of the test suite (make check).
+      - examples for examples.
+      - m4 for m4 files.
+  * Renamed configure.in to configure.ac.
+  * Added/updated Makefile.am files where needed.
+  * Updated acinclude.m4 and configure.ac (AC_CONFIG_FILES line).
+  * Updated the documentation (INSTALL, README, doc/README.dev and
+    doc/mpfr.texi).
+  * Updated NEWS and TODO.
+  * Updated the scripts now in tools.
+
+The following script was used:
+
+#!/usr/bin/env zsh
+svn mkdir doc other src tools tune
+svn mv ${${(M)$(sed -n '/libmpfr_la_SOURCES/,/[^\]$/p' \
+         Makefile.am):#*.[ch]}:#get_patches.c} mparam_h.in \

+Support implementations where the floating-point division by 0 fails.
+  * acinclude.m4: added a test to check whether the FP division by 0
+    fails, and define MPFR_ERRDIVZERO in such a case.
+  * tests/tests.c: if MPFR_TEST_DIVBYZERO is defined, test whether
+    there has been a floating-point division by 0 (FE_DIVBYZERO or
+    FE_INVALID exception).
+  * tests/tgeneric.c: if MPFR_ERRDIVZERO is defined, disable the

+[get_sj.c] Fixed bug found by John Regehr:
+https://gforge.inria.fr/tracker/index.php?func=detail&aid=10839&group_id=136&atid=619
+Note: the problem was an undefined behavior that could occur when
+sizeof(mp_limb_t) < sizeof(intmax_t) and |x| was small enough,
+because a right shift was >= the type width. However as the shifted
+value was 0, most platforms should not be affected by this bug. This
+problem was detected with clang -fcatch-undefined-ansic-behavior.

+* I added a new implementation of Airy Ai. This implementation uses Smith's
+algorithm.
+Currently, it is provided as a separate implementation mpfr_ai2.
+
+* Please note that both mpfr_ai and mpfr_ai2 need to efficiently evaluate
+Gamma(1/3) and Gamma(2/3). This is provided by functions in the file 
+gammaonethird.c
+
+* There is no test file for mpfr_ai2 since it should quickly disappear behind
+a single implementation using the best of mpfr_ai and mpfr_ai2.
+However, if necessary, a test file can be obtained by copying tai.c and 
+replacing mpfr_ai by mpfr_ai2 everywhere.
+
+* I do not know if gammaonethird.c will remain like that in the future. Should
+we make this implementation available as a public MPFR function? In this case,
+I have to write a wrapper for providing a correctly rounded implementation.
+Moreover, it contains functions that could be interesting for the 
+implementation of other functions (the functions mpfr_div_ui*). Maybe, it 
+could be worth providing a file specially for this purpose.

+Changed the precision type mpfr_prec_t from an unsigned integer type
+into the corresponding signed integer type, in order to avoid problems
+due to the usual arithmetic conversions when mixing mpfr_prec_t and
+mp_exp_t in an expression.
+* NEWS: mentioned this change.
+* mpfr-impl.h: removed MPFR_INTPREC_MAX (which wasn't used) and updated
+  the MPFR_UNSIGNED_MINUS_MODULO(S,A) macro, which assumed that A was
+  unsigned; this macro now works even when A is signed.
+* mpfr.h: added mpfr_uprec_t; updated mpfr_prec_t and MPFR_PREC_MAX.
+* tests/tcheck.c: disabled a test on MPFR_PREC_MAX+1 with MPFR >= 3
+  (this test doesn't work with a signed mpfr_prec_t and isn't needed).
+Note: all tests pass under GNU Linux x86 and x86_64.

+To avoid breaking the ABI when faithful rounding gets implemented, added
+MPFR_RNDF to the mpfr_rnd_t enum type now, and removed MPFR_RND_MAX from
+the enumeration (it is now defined as a macro in mpfr-impl.h).

+[fits_uintmax.c, fits_u.h] Some casts could be incorrect in the case
+mp_exp_t > mpfr_prec_t. Set prec to the int type since in practice,
+prec will be small enough to fit in an int. The fact that prec is now
+signed allows us to remove a useless test (also note that prec should
+be computed at compile time, so that this should be at least as fast).

+vasprintf.c: changeset r6414 was incorrect, in particular under Linux
+(at least some platforms), where wint_t is an unsigned int, not an int.
+Instead, let's detect whether integer promotion will occur or not, even
+though the ISO C99 standard requires a wint_t type that doesn't yield
+an integer promotion (7.24.1#2), because mingw32 defines wint_t as an
+unsigned short (thus with integer promotion).

+  checking for gcc float-conversion bug... yes, use -ffloat-store
+instead of

+Indeed the "volatile" has the effect to have all the intermediate

+Changed how the test of MPFR_VERSION_MAJOR, MPFR_VERSION_MINOR and
+MPFR_VERSION_PATCHLEVEL vs MPFR_VERSION_STRING is performed.
+Detailed explanations:
+  The test was enabled only in release tarballs (suffix not present),
+  where tests/tversion.c normally contained a "#if 1" (though this
+  is not the case in the MPFR 2.4.0 tarball). In patches, this test
+  should be disabled by changing the "#if 1" into "#if 0", due to
+  the suffix. But as one should be able to apply any patches (in any
+  order), this method was not satisfactory. The test has been moved
+  from tests/tversion.c to tests/tests.c (in function test_version),
+  and the suffix is now ignored in this test; the change of #if has
+  been removed from the update-version script.

+r5689 undone: some casts were incorrect (mp_exp_t may be greater than
+mp_prec_t, so that casting a mp_exp_t into a mp_prec_t can introduce a
+bug). There may be bugs in some cases, but the casts fix the symptom,
+not the bug (unless one casts the unsigned type to a signed type that
+is *strictly* larger, which is not possible here).

+
+Merged vlefevre branch:
+    svn merge -c-5445 .
+    svn merge -r5436:HEAD .../mpfr/branches/vlefevre
+* pow.c:
+  - Moved the general case from mpfr_pow() to a new internal function
+    mpfr_pow_general().
+  - In this function (from old code), avoid unnecessary overflow test
+    if the intermediate result is not an infinity (which was the case
+    of underflow with non-zero result, thus not an overflow).
+  - Fixed a double-rounding problem that occurred in this function in
+    some underflow cases when rescaling the result.
+  - Added log messages.
+* mpfr-impl.h: added mpfr_pow_general prototype.
+* pow_z.c:
+  - The underflow case of mpfr_pow_pos_z() in rounding to nearest,
+    which was incorrect, is now handled by calling mpfr_pow_general(),
+    which can scale the result thus decide whether the rounded result
+    should be 0 or nextabove(0). To avoid the exact cases of x^y with
+    y integer (not supported by mpfr_pow_general()), rounding is done
+    in precision 2 (this is also faster!).
+  - Fixed underflow-related bug (case exact result = 2^(emin-2), in
+    rounding to nearest).
+  - Added log messages.
+* pow_ui.c:
+  - Swapped parameters x and y for consistency (-> y = x^n).
+  - Fixed the internal overflows and underflows (which could yield
+    spurious overflows/underflows and incorrect results) by using
+    mpfr_pow_z.
+* tests/tpow_all.c:
+  - Test flags in test_others and cmpres; cmpres argument z1 can now
+    be a null pointer (if unknown pure FP value, thus not tested).
+  - Added a test of 2^(emin - i/4) with 0 <= i <= 12, that triggered
+    the bugs mentioned above (and now fixed).

+Clean-up and various changes to be able to build MPFR with g++.
+But the following 3 tests currently fail with g++ 4.3.1:
+  FAIL: tprintf
+  FAIL: tsprintf
+  FAIL: tfprintf
+This is an "Illegal instruction" error, so probably a bug in g++.
+[Edit: acinclude.m4 now uses gl_SIZE_MAX, typically from size_max.m4,
+but which is not installed on all machines; this will be added to the
+MPFR repository in changesets 5680 and 5683.]

+For the terminating null pointer of the functions mpfr_inits,
+mpfr_inits2, mpfr_clears, always use the type mpfr_ptr (no longer
+void *). Updated the description of these functions in the manual
+(mpfr.texi). The reason is that the C standard does not guarantee
+that (void *) 0 has the same representation as a null pointer to
+a structure (and even the same size). In most C implementations,
+the representations are the same, but one never knows (dynamical
+checking is also always possible)...
+The change has been done with: perl -pi -e \
+  's/(mpfr_(clear|init)s.*)\(void *\*\) *0\)/$1(mpfr_ptr) 0)/' **/*.c
+under zsh.

+In tests_default_random, allow emin and emax to be outside of the

+Changes related to mpfr_strtofr.
+  * strtofr.c: for mpfr_strtofr, data corresponding to NaN can now have
+    an optional sign (since the documentation said that parsing followed
+    the standard C strtod function and this change makes invalid data
+    now valid, so that there should be no compatibility problems).
+  * tests/tstrtofr.c: changed the test for -42P17 in base 16 (this was
+    eventually regarded as a documentation bug); added tests.
+  * mpfr.texi: almost completely rewrote the specification of the
+    mpfr_strtofr function. Changes:
+    - the binary exponent is now accepted even without the 0b or 0x
+      prefix;
+    - data corresponding to NaN can now have an optional sign (this was
+      a bit ambiguous);
+    - many other ambiguities avoided.

+Merged the feature-block branch to the trunk:
+* New MPFR_BLOCK* macros (see mpfr-impl.h) and mpfrlint check to test
+  exception flags in a more reliable way and detect possible problems
+  with mpfrlint.
+* Improved the generic tests (tests/tgeneric.c): for the second
+  function call, sometimes set all the flags since risk of failures
+  are known when some flags are already set.
+* Modified code to use these new MPFR_BLOCK* macros. This fixed bugs
+  related to exceptions (where flags are set before the call); in
+  particular, tcot and ty1 failed with the improved generic tests.

+Changeset r4904 introduced an assertion failure, but the assertion
+emax - emin >= PREC(x) wasn't necessary: the value of emax doesn't
+matter, except when the exponent is increased due to the rounding.
+So, we just document that if the result cannot be represented in the
+current exponent range, the behavior is undefined (updated mpfr.texi
+accordingly). Removed the assertion from subnormal.c and added a new
+one to have an abort if such an undefined behavior occurs.

+this file is just like any other .c files. Note: "make dist" includes

+Replaced l2b cache by constants, as suggested by Patrick Pelissier,
+to avoid efficiency problems with the stack interface and heavily
+threaded applications.
+  * Added tests/tl2b.c to generate / check the constants.
+  * tests/Makefile.am: added tl2b to check_PROGRAMS.
+  * tests directory: added tl2b to the svn:ignore property.
+  * mpfr-impl.h: updated the __gmpfr_l2b declaration.
+  * free_cache.c: disabled free_l2b (since there's no longer a cache).
+  * get_str.c: added the code generated by tl2b; for the bootstrap, one
+    can just write:
+      const __mpfr_struct __gmpfr_l2b[BASE_MAX-1][2] = { { { 0 } } };
+    Removed the code (in ceil_mul) that computed these constants.

+fixes mpfr_set_si_2exp and mpfr_set_ui_2exp in case of overflow or
+underflow (replacing the r4346 fix). Added corresponding testcases.

+pow_si.c: Before fixing the bug corresponding to the testcase added in
+rev 4342, let's fix another one that can be detected with -ftrapv when
+n = LONG_MIN (since -n is not representable in this case).
+With wrapping, we always got the correct result because mp_exp_t is
+currently at most a long *and* because of side effects!

+In particular, it is now set by mpfr_check_range (if t is not zero)
+since mpfr_check_range usually comes just after MPFR_SAVE_EXPO_FREE
+(which restores the previous flags).

+Optimized mpfr_expm1 for large (in absolute value) negative values in
+order to avoid the TMD (the result is very close to -1). Without this
+patch, mpfr_expm1 could take dozens of MBs and the new generic tests
+for texpm1 could take several hours instead of less than 1 second.

+
+Fixed a bug in expm1 for very small negative arguments (and perhaps
+some very small positive arguments too); this bug is similar to the
+one in log1p that was recently found and fixed. It was detected by
+the new generic tests (not committed yet), therefore no testcases
+are provided. Note: the mpfr_expm1 function is still buggy (freezes
+on -0.10E18, prec 2 -> prec 13); this is a different bug.

+
+Merged the changes from branch vlefevre:
+  * mpfr-impl.h: Added MPFR_RNDRAW_GEN based on MPFR_RNDRAW and
+    MPFR_RNDRAW_EVEN codes, but taking an additional argument: a
+    handler executed in rounding to nearest mode when the value
+    is the middle of two consecutive numbers in dest precision.
+    MPFR_RNDRAW and MPFR_RNDRAW_EVEN are now defined by a "call"
+    to MPFR_RNDRAW_GEN.
+  * cache.c: Clean-up and use MPFR_RNDRAW_GEN instead of
+    MPFR_RNDRAW_EVEN to avoid an unnecessary correction in the
+    halfway case.
+  * hypot.c: Fixed mpfr_hypot when the rounding mode is to nearest,
+    x is "much larger" than y, and x is the middle of two consecutive
+    numbers in the target precision.
+  * tests/thypot.c: Added the corresponding testcase.

+Add corresponding test case. exp_3 may need similar patchs.

++ Better support of non IEEE doubles.
++ You can compile MPFR without gmp internal files (ie gmp-impl.h, gmp-mparam.h, and config.h). You only need gmp.h and libgmp.a. But you can still compile with GMP internal files (configure detects them).

+Updated documentation. In particular, mpfr_set_str_raw renamed
+as mpfr_set_str_binary. This function and mpfr_print_binary are
+now internal functions. mpfr_print_binary no longer prints the
+non-significant 0 bits. Updated the source to match the manual.
+mpfr_print_binary has been completely rewritten (now directly
+prints to stdout, without using an intermediate string). In
+mpfr_set_str_binary, replaced atol by strtol + error checking.

+Re-added the assert on the exponent, but replacing MPFR_EMIN_MIN by
+MP_EXP_T_MIN (this makes more sense): an assertion failed would mean
+that the exponent is not representable (an undefined behavior in the
+ISO C standard). If need be, we could choose to return MP_EXP_T_MIN
+in such a case, or perhaps MP_EXP_T_MAX to signal an error. The
+mantissa would still be meaningful.

+
+                        Installing GNU MPFR
+                        ===================
+
+Note: In case of problem, please read this INSTALL file carefully before
+reporting a bug, in particular Section "In case of problem" below. Some
+problems are due to bad configuration on the user side (not specific to
+MPFR).
+
+0. You first need to install GMP. See <http://www.gnu.org/software/gmp/>.
+   MPFR requires GMP version 4.1 or later.
+
+1. Extract the files from the archive.
+
+2. It is strongly advised to apply the latest patches if this has
+   not been done yet and if patches are available. You can check
+   on the release page:
+
+     http://www.mpfr.org/mpfr-3.1.2/
+
+   which may have additional information. The patches can be applied
+   with commands like:
+
+     wget http://www.mpfr.org/mpfr-3.1.2/allpatches
+     patch -N -Z -p1 < allpatches
+
+   or
+
+     curl http://www.mpfr.org/mpfr-3.1.2/allpatches | patch -N -Z -p1
+
+   (Those instructions are for the GNU patch command, for example
+   /usr/bin/gpatch on Solaris.)
+
+3. In the MPFR directory, to detect your system, type:
+     ./configure
+   possibly with options (see below, in particular if this step or
+   one of the following fails). You should also check whether WARNING
+   lines have been output (such a problem may cause a failure in one
+   of the following steps).
+   Note: paths provided in configure options must always be absolute
+   (relative paths are not supported).
+
+4. To build the library, type:
+     make
+
+   [optional] if you want to tune MPFR for your specific architecture, see
+   the section "Tuning MPFR" below. Note that for most common architectures,
+   MPFR includes some default tuning parameters which should be near from
+   optimal.
+
+5. To check the built library (runs the test files), type:
+     make check
+
+6. To install it (default "/usr/local" | see "--prefix" option), type:
+     make install
+
+If you installed MPFR (header and library) in directories that are
+not searched by default by the compiler and/or linking tools, then,
+like with other libraries, you may need to set up some environment
+variables such as C_INCLUDE_PATH (to find the header mpfr.h),
+LIBRARY_PATH (to find the library), and if the shared library has
+been installed, LD_LIBRARY_PATH (before execution) or LD_RUN_PATH
+(before linking); this list is not exhaustive and some environment
+variables may be specific to your system. "make install" gives some
+instructions; please read them. You can also find more information
+in the manuals of your compiler and linker. The MPFR FAQ may also
+give some information.
+
+Remember that if you have several MPFR (or GMP) versions installed
+(e.g., one with the system, and one, newer, by you), you will not
+necessarily get a compilation/linking error if a wrong library is
+used (e.g., because LD_LIBRARY_PATH has not been set correctly).
+But unexpected results may occur.
+
+Under Mac OS X, if the shared library was not installed and you use
+Apple's linker (this is the default), you will also need to provide
+the -search_paths_first linker flag ("-Wl,-search_paths_first" when
+you link via gcc) to make sure that the right library is selected,
+as by default, Apple's linker selects a shared library preferably,
+even when it is farther in the library paths. We recall that if a
+wrong library is selected due to this behavior, unexpected results
+may occur.
+
+
+Building the documentation
+==========================
+
+To build the documentation in various formats, you may first need to
+install recent versions of some utilities such as texinfo.
+
+* Type "make info" to produce the documentation in the info format.
+
+* Type "make pdf" to produce the documentation in the PDF format.
+
+* Type "make dvi" to produce the documentation in the DVI format.
+
+* Type "make ps" to produce the documentation in the Postscript format.
+
+* Type "make html" to produce the documentation in the HTML format
+  (in several pages); if you want only one output HTML file, then
+  type "makeinfo --html --no-split mpfr.texi" from the doc directory
+  instead.
+
+
+Building MPFR with internal GMP header files
+============================================
+
+MPFR built with internal GMP header files is a bit faster, so you may want
+to build it with them. Just do this in step 1:
+
+  ./configure --with-gmp-build=GMPBUILD
+
+where GMPBUILD is the GMP build directory. The needed header files are:
+gmp-impl.h, longlong.h and all the necessary headers to use them, which
+may be located either in the GMP source directory or in the GMP build
+directory, in case they are different (MPFR takes care of that, as of
+MPFR 3.1.0).
+
+Warning: the library obtained in this way may use some internal GMP
+symbols, and thus dynamically linking your software with a different
+version of GMP might fail, even though it is declared as compatible
+by Libtool's versioning system.
+
+
+Tuning MPFR
+===========
+
+For this, you need to build MPFR with a GMP build directory (see above).
+In the GMP build directory, you also need to go into the "tune" subdirectory
+and type "make speed". This will build the GMP speed library, which is used
+by the MPFR tuning mechanism.
+
+Then go back to the MPFR build directory, go into the "tune" subdirectory and
+type "make tune". This will build an optimized file "mparam.h" for your
+specific architecture.
+
+
+./configure options
+===================
+
+--prefix=DIR            installs MPFR headers and library in DIR/include and
+                        DIR/lib respectively (the default is "/usr/local").
+
+--with-gmp-include=DIR  assumes that DIR contains gmp.h
+--with-gmp-lib=DIR      assumes that DIR contains the GMP library
+--with-gmp=DIR          assumes that DIR is where you have installed GMP.
+                        same as --with-gmp-lib=DIR/lib
+                        and     --with-gmp-include=DIR/include
+                        (use either --with-gmp alone or one or both of
+                        --with-gmp-lib/--with-gmp-include)
+                        Warning! Do not use these options if you have
+                        CPPFLAGS and/or LDFLAGS containing a -I or -L
+                        option with a directory that contains a GMP
+                        header or library file, as these options just
+                        add -I and -L options to CPPFLAGS and LDFLAGS
+                        *after* the ones that are currently declared,
+                        so that DIR will have a lower precedence. Also,
+                        this may not work if DIR is a system directory
+                        (typically /usr or /usr/local); see below.
+
+--with-gmp-build=DIR    assumes that DIR contains the GMP build directory,
+                        and enables the use of GMP internals (see above).
+                        Warning! This option and the group of options
+                        --with-gmp are mutually exclusive.
+
+--enable-assert         build MPFR with assertions.
+
+--enable-thread-safe    build MPFR as thread safe, using compiler-level
+                        Thread Local Storage (TLS). Note: TLS support is
+                        roughly tested by configure. If configure detects
+                        that TLS does not work (because of the compiler,
+                        linker or system libraries), it will output an
+                        error message, telling you to build MPFR without
+                        thread safe. For instance, though Mac OS X uses
+                        GCC, it may not currently support GCC's __thread
+                        storage class.
+
+--disable-thread-safe   build MPFR without TLS. By default, TLS support
+                        is detected automatically, and MPFR is built as
+                        thread safe if supported. However this detection
+                        is only a heuristic: TLS can be detected as
+                        supported while its support is incomplete or
+                        buggy (MPFR tests may fail). In such a case,
+                        this option is useful.
+
+--enable-gmp-internals  allows the MPFR build to use GMP's undocumented
+                        functions (not from the public API). Note that
+                        library versioning is not guaranteed to work if
+                        this option is used. Thus it must not be used in
+                        binary distributions.
+
+Note: By default, the configure script tries to set CC/CFLAGS to GMP's
+ones (this feature needs GMP 4.3.0 or later, or the --with-gmp-build
+option). However this is not guaranteed to work as the configure script
+does some compiler tests earlier, and the change may be too late. Also,
+the values obtained from GMP may be incorrect if GMP has been built
+on a different machine. In such a case, the user may need to specify
+CC/CFLAGS as explained below.
+
+Run "./configure --help" to see the other options (autoconf default options).
+
+
+If 'gmp.h' and 'libgmp' do not match
+====================================
+
+Under some circumstances, the configure script may output a message
+saying:
+
+  'gmp.h' and 'libgmp' seem to have different versions or
+  we cannot run a program linked with GMP (if you cannot
+  see the version numbers above). [...]
+
+Even though the configure script does not fail in such a case, this
+message most often indicates a real error, which needs to be avoided.
+Possible causes are:
+
+* The wanted GMP library does not have the same ABI as the one chosen
+  to build MPFR. The consequences may be:
+
+    - A different GMP library (with the correct ABI) has been found,
+      but does not have the same version as 'gmp.h'.
+
+    - No other GMP libraries have been found (in this case, no version
+      numbers should be printed above the warning message).
+
+  This is incorrect and one of the following steps (make, make check)
+  will probably fail. GMP (actually gmp.h) now provides CC and CFLAGS
+  information to select the correct ABI, so that this problem should
+  no longer occur; but if GMP was provided by a binary package, such
+  information may not be valid. See the
+
+    checking for CC and CFLAGS in gmp.h...
+
+  line in the configure output (about the 11th line) and the following
+  few ones for more information. You may need to reinstall GMP or to
+  provide your own CC and/or CFLAGS. See also the remaining of this
+  INSTALL file.
+
+* A configure option like --with-gmp or --with-gmp-include was used
+  with a system include directory, e.g. one of the following:
+
+    --with-gmp=/usr
+    --with-gmp=/usr/local
+    --with-gmp-include=/usr/include
+    --with-gmp-include=/usr/local/include
+
+  GCC (and possibly other compilers) will ignore such a directive for
+  include directories (but this rule is not applied for the library
+  itself!). This means that the library search paths will be reordered
+  as declared, but the specified include directory will still be near
+  the end of the include search paths (thus with a low precedence).
+  This is not a problem if only one GMP version is installed, but
+  otherwise, a wrong gmp.h may be chosen, so that the versions of
+  gmp.h and libgmp may not match. The suggestions are the following:
+
+    - If you want to use the GMP version under /usr, then you should
+      uninstall all the other GMP versions (header and library files)
+      that may be seen in the search paths, in particular those under
+      /usr/local.
+
+    - If you want to use the GMP version under /usr/local, then you
+      should uninstall all the other GMP versions (header and library
+      files) that may be seen in the search paths, but *NOT* the one
+      under /usr (the version under /usr is provided by the OS vendor,
+      and changing/removing anything related to it may break your
+      system, and /usr should have a lower precedence than /usr/local
+      anyway).
+
+  To find where GMP versions have been installed:
+
+    $ locate libgmp  (if you have a locate database)
+
+  and if the compiler is GCC:
+
+    $ gcc -print-file-name=libgmp.so     (under most systems)
+    $ gcc -print-file-name=libgmp.dylib  (under Mac OS X)
+
+  and if this does not work, you may try:
+
+    $ gcc -print-search-dirs
+
+* An official GCC version was used under Debian GNU/Linux. Problems
+  may come from the fact that Debian chose a different convention
+  for library search paths concerning 32-bit and 64-bit libraries.
+  A possible problem can be, for instance:
+
+  [Debian's GCC, correct library path]
+  $ gcc -print-file-name=libgmp.so
+  /home/vlefevre/gmp/athlon64/lib/../lib/libgmp.so
+
+  [Official GCC, incorrect library path]
+  $ gcc-4.3.1 -print-file-name=libgmp.so
+  /usr/lib/../lib64/libgmp.so
+
+  The solution: use a GCC provided by Debian or add symbolic links
+  such as lib64 -> lib (on 64-bit machines) for your library paths.
+
+* The problem may also be temporary and only due to the fact that
+  libtool could not be used at this time. This is unlikely, though.
+
+
+In case of problem
+==================
+
+First, look for any warning message in the configure output.
+
+Several documents may help you to solve the problem:

+
+If the "configure" fails, please check that the C compiler and its
+options are the same as those for the GMP build (specially the ABI).
+You can see the latter with the following command:
+
+  grep "^CC\|^CFLAGS" GMPBUILD/Makefile
+
+if the GMP build directory is available. Then type:
+
+  ./configure <configure options> CC=<C compiler> CFLAGS="<compiler options>"
+
+(quotes are needed when there are spaces or other special characters
+in the CC/CFLAGS value) and continue the install. On some platforms,
+you should provide further options to match those used by GMP, or set
+some environment variables. For instance, see the "Notes on AIX/PowerPC"
+section below.
+
+Warning! Do NOT use optimization options that can change the semantics
+of math operations, such as GCC's -ffast-math or Sun CC's -fast.
+Otherwise conversions from/to double's may be incorrect on infinities,
+NaN's and signed zeros. Since native FP arithmetic is used in a few
+places only, such options would not make MPFR faster anyway.
+
+If some "make check" tests fail, you can try the --disable-thread-safe
+configure option (see the configure options above): it has been reported
+that some platforms have buggy TLS support. Before trying this option,
+you may want to check in the configure output whether MPFR was built
+with TLS support; if yes, you will have a line:
+  checking for TLS support... yes
+Alternatively "grep MPFR_USE_THREAD_SAFE config.log" will show that
+MPFR_USE_THREAD_SAFE is defined to 1. If it is "no" (or the variable
+is not defined), the --disable-thread-safe option would be useless.
+
+Some tests failure may be due to other compiler bugs, in particular
+in optimization code. You can try to build MPFR without compiler
+optimizations by giving -O0 (letter O, digit 0) in CFLAGS. If the
+MPFR tests no longer fail, this was probably due to a compiler bug,
+though we cannot exclude a bug in MPFR. You may want to contact us
+(see below), possibly after looking at:
+  http://www.loria.fr/~zimmerma/software/compilerbugs.html
+
+On some platforms, try with "gmake" (GNU make) instead of "make".
+Problems have been reported with the Tru64 make.
+
+If the configure script reports that gmp.h version and libgmp version
+are different, or if the build was OK, but the tests failed to link
+with GMP or gave an error like
+
+  undefined reference to `__gmp_get_memory_functions'
+
+meaning that the GMP library was not found or a wrong GMP library was
+selected by the linker, then your library search paths are probably
+not correctly set (some paths are missing or they are specified in an
+incorrect order).
+
+Such problems commonly occur under some GNU/Linux machines, where the
+default header and library search paths may be inconsistent: GCC is
+configured to search /usr/local/include and /usr/local/lib by default,
+while the dynamic linker ignores /usr/local/lib. If you have a GMP
+version installed in /usr (provided by the OS vendor) and a new one
+installed in /usr/local, then the header of the new GMP version and
+the library of the old GMP version will be used! The best solution
+is to make sure that the dynamic linker configuration is consistent
+with GCC's behavior, for instance by having /usr/local/lib in
+/etc/ld.so.conf or in some file from /etc/ld.so.conf.d (as Debian
+did: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=395177). See
+also http://gcc.gnu.org/ml/gcc-help/2010-01/msg00171.html for more
+information. Alternatively you can use:
+  * environment variables. This may sometimes be necessary. If DIR
+    is the installation directory of GMP, add DIR/include to your
+    CPATH or C_INCLUDE_PATH (for compilers other than GCC, please
+    check the manual of your compiler), and add DIR/lib to your
+    LIBRARY_PATH and LD_LIBRARY_PATH (and/or LD_RUN_PATH);
+  * --with-gmp* configure options (described above), e.g.
+    --with-gmp=/opt/local (to use /opt/local/include for headers and
+    /opt/local/lib for libraries), but other software that uses GMP
+    and/or MPFR will need correct paths too, and environment variables
+    allow one to set such search paths in a global way.
+    Note about "--with-gmp=/usr/local". This option may appear to
+    solve the above inconsistency problem, but does not work as you
+    expect. Indeed it affects the library search path, in particular,
+    the one used by the dynamic linker (thus adding the missing
+    /usr/local/lib directory as wanted), but since /usr/local/include
+    is a "standard system include directory" for GCC, the include
+    search patch is not changed; this is often not a problem in this
+    particular case because usually, /usr/local/include is already
+    last in the include search patch, but this may fail under some
+    occasions and may trigger obscure errors.
+
+For instance, under Unix, where paths are separated by a colon:
+
+  * With POSIX sh-compatible shells (e.g. sh, ksh, bash, zsh):
+    export C_INCLUDE_PATH="/usr/local/include:/other/path/include"
+    export LIBRARY_PATH="/usr/local/lib:/other/path/lib"
+    export LD_LIBRARY_PATH="$LIBRARY_PATH"
+
+  * With csh or tcsh:
+    setenv C_INCLUDE_PATH "/usr/local/include:/other/path/include"
+    setenv LIBRARY_PATH "/usr/local/lib:/other/path/lib"
+    setenv LD_LIBRARY_PATH "$LIBRARY_PATH"
+
+If you can't solve your problem, you should contact us via the MPFR
+mailing-list <mpfr@inria.fr>, indicating the machine and operating system
+used (uname -a), the compiler and version used (gcc -v if you use gcc),
+the configure options used if any (including variables such as CC and
+CFLAGS), the version of GMP and MPFR used, and a description of the
+problem encountered. Please send us also the log of the "configure"
+(config.log).
+
+Note that even if you can build MPFR with a C++ compiler, you can't run
+the test suite: C and C++ are not the same language! You should use a C
+compiler instead.
+
+
+Notes about ABI
+===============
+
+On 64-bit computers, it may happen that the default ABI (Application Binary
+Interface) chosen by MPFR does not correspond to the default one chosen by
+the compiler.
+
+In particular, this kind of message may indicate the problem:
+/usr/bin/ld: skipping incompatible mpfr/src/.libs/libmpfr.a when searching for -lmpfr
+
+In fact, since MPFR relies on GMP, it uses the same ABI as GMP.
+To be sure that your program compiles and links correctly, use the same
+compiler flags as MPFR does (look for CFLAGS in config.log).
+
+You might also recompile GMP with a different ABI, with for example
+./configure ABI=32.
+
+
+Notes on Mac OS X
+=================
+
+If you get an error of the form
+
+  ld: pointer in read-only segment not allowed in slidable image...
+
+this can mean that the link is done against a static (GMP) library.
+In such a case, you should configure MPFR with --disable-shared to
+disable the build of the shared library.
+
+
+Notes on FreeBSD 4.3
+====================
+
+FreeBSD 4.3 is provided with an incorrect <float.h> header file, and
+MPFR tests related to long double's may fail. If you cannot upgrade
+the system, you can still use MPFR with FreeBSD 4.3, but you should
+not use conversions with the long double type.
+
+
+Notes on AIX/PowerPC
+====================
+
+The following has been tested on AIX 5.3 (powerpc-ibm-aix5.3.0.0) with
+gcc 3.3.2 and GMP 4.2.1.
+
+If GMP was built with the 64-bit ABI, before building and testing MPFR,
+you should set the OBJECT_MODE environment variable to 64, e.g., with:
+
+  export OBJECT_MODE=64
+
+(in a sh-compatible shell). But you should also provide a correct CFLAGS
+value to the "configure" script: using --with-gmp-build is not sufficient
+due to the early compiler tests, as gcc will not compile any program if
+OBJECT_MODE is 64 and the -maix64 option is not provided.
+
+
+MPFR for use with 32-bit Windows Applications (win32)
+=====================================================
+
+There are several ways of building MPFR on Windows, the most appropriate
+approach depending on how you intend to use the resulting libraries.
+
+a. Using MinGW
+==============
+
+1 - We advise to use MinGW (http://www.mingw.org/), which is simpler and
+    less demanding than Cygwin. Contrary to Cygwin, it also provides native
+    Windows code.
+
+2 - If you just want to make a binary with gcc, there is nothing to do:
+    GMP, MPFR and the program compile exactly as under Linux.
+    But if you want to generate a library for MinGW from a Cygwin
+    environment, you may need the -mno-cygwin gcc option (otherwise
+    a typical error is _P_WAIT being undeclared).
+
+3 - If you want to make libraries work under another Windows compiler
+    like Visual C / C++, since the unix-like *.a library files are compatible
+    with Windows *.lib files, you can simply rename all *.a libraries to *.lib.
+
+    With gmp-4.1.3, the only remaining problem seems to be the "alloca" calls
+    in GMP. Configuring GMP and MPFR with --enable-alloca=malloc-reentrant
+    should work (if you build MPFR with GMP internal files).
+
+    Or you could add the library
+     "$MINGWIN$/lib/gcc-lib/mingw32/$VERSION$/libgcc.a"
+    to your project: it contains all the extra-functions needed by a program
+    compiled by gcc (division of 64-bit integer, bcopy, alloca...).
+    Of course, include it if and only if your compiler is not gcc.
+
+4 - On Windows32 / MinGW, if all the tests fail, try to run the test suite
+    with "make check EXEEXT=".
+
+5 - To avoid using the Microsoft runtime (which might not be conform to ISO C),
+    you can use the MinGW runtime package (which is an integral part of MinGW).
+    For example, with MinGW versions 3.15 and later you can get an
+    ISO-compliant printf() if you compile your application with either
+    '-ansi', '-posix' or '-D__USE_MINGW_ANSI_STDIO'. For example, you can
+    compile and test MPFR with CC="gcc -D__USE_MINGW_ANSI_STDIO".
+
+    For example under Win32, the following problem has been experienced with
+    MPFR 2.4.0 RC1 and the MSVC runtime (msvcrt.dll):
+
+       Error in mpfr_vsprintf (s, "%.*Zi, %R*e, %Lf%n", ...);
+       expected: "00000010610209857723, -1.2345678875e+07, 0.032258"
+       got:      "00000010610209857723, -1.2345678875e+07, -0.000000"
+       FAIL: tsprintf.exe
+
+    This error is due to the MSVC runtime not supporting the L length modifier
+    for formatted output (e.g. printf with %Lf). You can check this with the
+    following program:
+
+       #include <stdio.h>
+       int main (void)
+       {
+         long double d = 1. / 31.;
+         printf ("%Lf\n", d);
+         return 0;
+       }
+
+    The expected output is 0.032258.
+
+    Note: The L modifier has been standard for a long time (it was added
+    in ISO C89).
+
+    Note 2: this now works correctly with Visual C++ 2008 and 2010
+    (tested on Microsoft (R) 32-bit C/C++ Optimizing Compiler Version
+     15.00.21022.08 for 80x86, Microsoft (R) C/C++ Optimizing Compiler
+     Version 15.00.21022.08 for x64, Microsoft (R) 32-bit C/C++ Optimizing
+     Compiler Version 16.00.30319.01 for 80x86, Microsoft (R) C/C++ Optimizing
+     Compiler Version 16.00.30319.01 for x64).
+
+b. Using Cygwin
+===============
+
+This build should be similar to that for MinGW except that the resulting
+library depends on the Cygwin DLL and cannot therefore be used with
+Visual Studio as with MinGW. Indeed, the binaries compiled with Cygwin
+require a dynamic library (cygwin.dll) to work; there is a Cygwin option
+-mno-cygwin to build native code, but it may require some non-portable tricks.
+
+In case of failure, you may need to pass LDFLAGS='-shared-libgcc' at the
+end of the configure line due to a bug in GCC. Otherwise, if threading
+support is not needed, you can configure MPFR with --disable-thread-safe.
+
+c. Using Visual C++ 2008/2010
+=============================
+
+Win32 versions of the MPFR library can be built using Microsoft Visual
+C++ 2008 or 2010 using the build projects available here:
+
+http://gladman.plushost.co.uk/oldsite/computing/gmp4win.php
+
+These build projects contain both win32 and x64 builds but the latter
+will give errors if your version of Visual C++ lacks the 64-bit
+compiler and tools.   The 32-bit build projects should however work
+on Visual C++ 2008, Visual C++ Express 2008 (SP1), Visual C++ 2010
+and Visual C++ Express 2010.
+
+MPFR for use with 64-bit Windows Applications (x64)
+===================================================
+
+There are two ways of building MPFR for use with 64-bit Windows
+applications.
+
+a. Using MinGW64
+================
+
+The MinGW64 version of the GCC compiler is now available here:
+
+http://sourceforge.net/projects/mingw-w64/
+
+It can build both GMP and MPFR for 64-bit Windows applications.
+
+b. Using Visual C++ 2008/2010
+=============================
+
+x64 versions of the MPFR library can be built using Microsoft Visual
+C++ 2008 or 2010 using the build projects available here:
+
+http://gladman.plushost.co.uk/oldsite/computing/gmp4win.php
+
+These build projects contain both win32 and x64 builds but the latter
+can only be built if your version of Visual C++ contains the 64-bit
+compiler and tools.  On Visual C++ 2008, the 64-bit tools are an
+option during installation so if you don't have them you will need
+to start the Visual Studio installer and add them to your IDE
+configuration.  On Visual C++ 2010 they are installed by default.
+
+As delivered, Visual C++ Express 2008 SP1 cannot build x64 projects
+but the Windows SDK can be added to it to allow this. The IDE then
+needs to be configured as described here:
+
+http://msdn.microsoft.com/en-us/library/9yb4317s(VS.80).aspx
+
+to allow x64 builds.
+
+Visual C++ Express 2010 requires the Windows 7 SDK to be installed
+in order to build x64 projects. This SDK is available here:
+
+http://tinyurl.com/25zz8r6
+
+In this case, once this SDK has been installed, Visual C++ Express 2010
+will build x64 projects without further changes.

+##############################################################################
+
+Changes from version 3.1.1 to version 3.1.2:
+- Bug fixes (see <http://www.mpfr.org/mpfr-3.1.1/#fixed> or ChangeLog file).
+- Updated examples to the MPFR 3.x API.
+- Note: The official tarballs for MPFR up to 3.1.1 were affected by a
+  vulnerability for "make distcheck" due to a bug in old GNU Automake
+  versions: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-3386
+
+Changes from version 3.1.0 to version 3.1.1:
+- Improved MPFR manual.
+- Test coverage: 96.5% lines of code.
+- Bug fixes (see <http://www.mpfr.org/mpfr-3.1.0/#fixed> or ChangeLog file).
+
+Changes from versions 3.0.* to version 3.1.0:
+- The "canard à l'orange" release.
+- The MPFR source has been reorganized.
+- Dropped ansi2knr support.
+- TLS support is now detected automatically. If TLS is supported, MPFR is
+  built as thread safe by default. To disable TLS explicitly, configure
+  MPFR with --disable-thread-safe.
+- New --enable-gmp-internals configure option to use GMP's undocumented
+  functions (not from the public API). Note that library versioning is
+  not guaranteed to work if this option is used.
+- The mpfr_urandom and mpfr_urandomb functions now return identical values
+  on processors with different word size (assuming the same random seed, and
+  since the GMP random generator does not depend itself on the word size,
+  cf http://gmplib.org/list-archives/gmp-devel/2010-September/001642.html).
+- The mpfr_add_one_ulp and mpfr_sub_one_ulp macros (which are obsolete and
+  no more documented) will be removed in a future release.
+- Speed improvement for the mpfr_sqr and mpfr_div functions using Mulders'
+  algorithm. As a consequence, other functions using those routines are
+  also faster.
+- Much faster formatted output (mpfr_printf, etc.) with %Rg and similar.
+- The --with-gmp-build configure option can now be used when the GMP
+  source directory and the GMP build directory are different (without
+  having to copy header files manually as before).
+- New functions mpfr_buildopt_gmpinternals_p, mpfr_buildopt_tune_case,
+  mpfr_frexp, mpfr_grandom and mpfr_z_sub.
+- New divide-by-zero exception (flag) and associated functions.
+- The mpfr.h header can be included several times, while still supporting
+  optional functions (see Section "Headers and Libraries" in the manual).
+- Updated tuning parameters.
+- Improved MPFR manual.
+- MPFR tests: libtool no longer generates wrapper scripts with "make check"
+  (so that running the tests under valgrind or gdb is easier).
+- Internal change: the logging mechanism has been improved.
+- Test coverage: 95.2% lines of code.
+- Bug fixes, in particular a huge inefficiency in mpfr_exp (when the
+  target precision is less than MPFR_EXP_THRESHOLD) on hard-to-round
+  cases, which can take several minutes.
+  Note: The mpfr_subnormalize implementation up to MPFR 3.0.0 did not change
+  the flags. In particular, it did not follow the generic rule concerning
+  the inexact flag (and no special behavior was specified). The case of the
+  underflow flag was more a lack of specification.
+
+Changes from versions 2.4.* to version 3.0.0:
+- The "boudin aux pommes" release.
+- MPFR 3.0.0 is binary incompatible with previous versions but (almost)
+  API compatible.  More precisely the obsolete functions mpfr_random
+  and mpfr_random2 have been removed, the meaning of the return type
+  of the function mpfr_get_f has changed, and the return type of the
+  function mpfr_get_z is now int instead of void.  In practice, this
+  should not break any existing code.
+- MPFR is now distributed under the GNU Lesser General Public License
+  version 3 or later (LGPL v3+).
+- Rounding modes GMP_RNDx are now MPFR_RNDx (GMP_RNDx kept for
+  compatibility).
+- A new rounding mode (MPFR_RNDA) is available to round away from zero.
+- The rounding mode type is now mpfr_rnd_t (as in previous versions,
+  both mpfr_rnd_t and mp_rnd_t are accepted, but mp_rnd_t may be
+  removed in the future).
+- The precision type is now mpfr_prec_t (as in previous versions, both
+  mpfr_prec_t and mp_prec_t are accepted, but mp_prec_t may be removed
+  in the future) and it is now signed (it was unsigned in MPFR 2.*, but
+  this was not documented). In practice, this change should not affect
+  existing code that assumed nothing on the precision type.
+- MPFR now has its own exponent type mpfr_exp_t, which is currently
+  the same as GMP's mp_exp_t.
+- Functions mpfr_random and mpfr_random2 have been removed.
+- mpfr_get_f and mpfr_get_z now return a ternary value.
+- mpfr_strtofr now accepts bases from 37 to 62.
+- mpfr_custom_get_mantissa was renamed to mpfr_custom_get_significand
+  (mpfr_custom_get_mantissa is still available via a #define).
+- Functions mpfr_get_si, mpfr_get_ui, mpfr_get_sj, mpfr_get_uj,
+  mpfr_get_z and mpfr_get_z_2exp no longer have cases with undefined
+  behavior; in these cases, the behavior is now specified, and in
+  particular, the erange flag is set.
+- New functions mpfr_buildopt_tls_p and mpfr_buildopt_decimal_p giving
+  information about options used at MPFR build time.
+- New function mpfr_regular_p.
+- New function mpfr_set_zero.
+- New function mpfr_digamma.
+- New function mpfr_ai (incomplete, experimental).
+- New functions mpfr_set_flt and mpfr_get_flt to convert from/to the
+  float type.
+- New function mpfr_urandom.
+- New function mpfr_set_z_2exp (companion to mpfr_get_z_2exp, which
+  was renamed from mpfr_get_z_exp in previous versions).
+- New function mpfr_min_prec.
+- Speed improvement for large precisions in the trigonometric functions
+  (mpfr_sin, mpfr_cos, mpfr_tan, mpfr_sin_cos): speedup of about 2.5
+  for 10^5 digits, of about 5 for 10^6 digits.
+- Speed improvement for large precisions of the inverse trigonometric
+  functions (arcsin, arccos, arctan): about 2 for 10^3 digits, up to
+  2.7 for 10^6 digits.
+- Some documentation files are installed in $docdir.
+- The detection of a GMP build directory (more precisely, the internal
+  header files of GMP) was previously done separately from the use of
+  the --with-gmp-build configure option. This was not consistent with
+  the documentation and with other parts of the configure script. So,
+  as of MPFR 3.0.0, the internal header files of GMP are now used if
+  and only if the --with-gmp-build configure option is given.
+- The configure script recognizes some extra "long double" formats
+  (double big endian, double little endian, double-double big endian).
+- MPFR manual: added "API Compatibility" section.
+- Test coverage: 97.1% lines of code.
+- Bug fixes.
+
+Changes from versions 2.3.* to version 2.4.0:
+- The "andouillette sauce moutarde" release.
+- MPFR is now a GNU package.
+- Changes in the behavior of mpfr_strtofr and in its documentation
+  concerning particular cases where the code and the documentation
+  did not match; this change is also present in MPFR 2.3.1.
+- Behavior of mpfr_check_range changed: if the value is an inexact
+  infinity, the overflow flag is set (in case it was lost); this
+  change is also present in MPFR 2.3.2.
+- Function mpfr_init_gmp_rand (only defined when building MPFR without
+  the --with-gmp-build configure option) is no longer defined at all.
+  This function was private and not documented, and was used only in
+  the MPFR test suite. User code that calls it is regarded as broken
+  and may fail as a consequence. Running the old test suite against
+  MPFR 2.4.0 may also fail.
+- New functions:
+  * between a MPFR number and a double: mpfr_add_d, mpfr_sub_d,
+    mpfr_d_sub, mpfr_mul_d, mpfr_div_d, mpfr_d_div,
+  * formatted input/output:
+    mpfr_printf, mpfr_fprintf, mpfr_vprintf, mpfr_vfprintf,
+    mpfr_sprintf, mpfr_snprintf, mpfr_vsprintf, mpfr_vsnprintf,
+    mpfr_asprintf, mpfr_vasprintf.
+  * mpfr_sinh_cosh, mpfr_li2, mpfr_modf, mpfr_fmod, mpfr_rec_sqrt.
+- Configure test for TLS support.
+- Get default $CC and $CFLAGS from gmp.h (__GMP_CC / __GMP_CFLAGS,
+  which are available as of GMP 4.2.3).
+- Documented the fact that mpfr_random and mpfr_random2 will be
+  suppressed in the next release, and that the specification of
+  mpfr_eq may change in the next release (for compatibility with
+  the mpf layer of GMP).
+- Test coverage: 96.7% lines of code.
+- Bug fixes.
+
+Changes from versions 2.2.* to version 2.3.0:
+- The mpfr.info file is now installed in the share subdirectory
+  (as required by the Filesystem Hierarchy Standard); see output
+  of "./configure --help".
+- The shared library is now enabled by default. If the MPFR build
+  fails on your platform, try the --disable-shared configure option
+  to disable the shared library.
+- Thread-safe support with Microsoft Visual compiler.
+- New functions mpfr_j0, mpfr_j1, mpfr_jn, mpfr_y0, mpfr_y1, mpfr_yn,
+  mpfr_lgamma, mpfr_remainder, mpfr_remquo, mpfr_fms, mpfr_signbit,
+  mpfr_setsign, mpfr_copysign, mpfr_get_patches.
+- Functions mpfr_sin, mpfr_cos and mpfr_sin_cos improved (argument
+  reduction).
+- More detailed MPFR manual.
+- Improved tests (make check).
+- Bug fixes.
+
+Changes from versions 2.1.* to version 2.2.0:
+- Bug fixes.
+- new functions mpfr_set_overflow, mpfr_set_underflow, mpfr_set_inexflag,
+  mpfr_set_erangeflag, mpfr_set_nanflag, mpfr_erfc, mpfr_atan2, mpfr_pow_z,
+  mpfr_subnormalize, mpfr_const_catalan, mpfr_sec, mpfr_csc, mpfr_cot,
+  mpfr_root, mpfr_eint, mpfr_get_f, mpfr_sech, mpfr_csch, mpfr_coth,
+  mpfr_lngamma.
+- new macro: MPFR_VERSION_STRING
+- Remove the exported MPFR variables from mpfr.h to mpfr-impl.h.
+  (They were undocumented, so programs which respect the API still work).
+- Grep CC and CFLAGS from GMP Makefile if possible.
+- Math functions are faster (both average and worst cases).
+- Better support for long double.
+- Shared library of MPFR.
+- Binary compatible with previous versions if you do not use undocumented
+  features.
+- Thread safe (if built with --enable-thread-safe).
+- Logging facility.
+- Change in the semantics of mpfr_out_str/mpfr_get_str when n_digits=0.
+- Better locale support.
+
+Changes from version 2.1.0 to version 2.1.1:
+- Better way to detect the GMP library.
+- Bug fixes.
+
+Changes from version 2.0.3 to version 2.1.0:
+- Bug fixes.
+- new functions mpfr_strtofr, mpfr_set_uj, mpfr_set_sj, mpfr_set_ui_2exp,
+  mpfr_set_si_2exp, mpfr_set_sj_2exp, mpfr_set_uj_2exp, mpfr_get_uj,
+  mpfr_get_sj, mpfr_get_z, mpfr_free_str, mpfr_si_sub, mpfr_sub_si,
+  mpfr_mul_si, mpfr_si_div, mpfr_div_si, mpfr_sqr, mpfr_cmp_z, mpfr_cmp_q,
+  mpfr_zero_p, mpfr_free_cache, mpfr_sum, mpfr_get_version,
+  mpfr_get_default_rounding_mode, mpfr_get_emin_min, mpfr_get_emin_max,
+  mpfr_get_emax_min, mpfr_get_emax_max, mpfr_inits, mpfr_inits2, mpfr_clears,
+  mpfr_fits_intmax_p, mpfr_fits_uintmax_p, mpfr_clear_erangeflag,
+  mpfr_erangeflag_p, mpfr_rint_round, mpfr_rint_trunc, mpfr_rint_ceil,
+  mpfr_rint_floor.
+- new macros MPFR_DECL_INIT, MPFR_VERSION, MPFR_VERSION_NUM,
+  MPFR_VERSION_MAJOR, MPFR_VERSION_MINOR, MPFR_VERSION_PATCHLEVEL.
+- improved documentation.
+- improved configure.
+- improved portability (library and test suite).
+- It handles correctly non IEEE-754 double.
+- GMP internal files are not needed to install MPFR.
+- It is faster with low-precision floating point.
+- New global flag: ERANGE_FLAG.
+- Binary incompatible with previous versions, but API compatible.
+- mpfr_set_str doesn't allow anymore "@NAN@garbagechar" and "@INF@garbagechar",
+  allows base 0 (detection of the base), prefix (0x, 0b), leading whitespace.
+
+Changes from version 2.0.2 to version 2.0.3:
+- Bug fixes.
+- Support GMP as a shared library (not fully tested).
+
+Changes from version 2.0.1 to version 2.0.2:
+- many bug fixes and other improvements.
+- new functions mpfr_prec_round (replaces mpfr_round_prec), mpfr_get_exp,
+  mpfr_set_exp, mpfr_get_ld, mpfr_set_ld, mpfr_get_d_2exp, mpfr_get_si,
+  mpfr_get_ui, mpfr_nextabove, mpfr_nextbelow, mpfr_nexttoward, mpfr_frac,
+  mpfr_fits_*, mpfr_cmp_d, mpfr_cmpabs, mpfr_erf, mpfr_gamma, mpfr_zeta,
+  mpfr_greater_p, mpfr_greaterequal_p, mpfr_less_p, mpfr_lessequal_p,
+  mpfr_lessgreater_p, mpfr_equal_p, mpfr_unordered_p.
+- removed functions: mpfr_print_binary, mpfr_round_prec (replaced by
+  mpfr_prec_round), mpfr_set_str_raw, mpfr_set_machine_rnd_mode.
+- function mpfr_isinteger renamed mpfr_integer_p.
+- return type of some functions changed from void to int, for consistency.
+- return type of mpfr_set_prec changed from int to void.
+- new values for exponent range.
+- rename internal variables.
+
+Changes from version 2001 to version 2.0.1:
+- new mathematical functions: acos, acosh, asin, asinh, atan, atanh, cosh,
+  base-2 exponential and logarithm, base-10 logarithm, expm1, factorial,
+  pow, pow_si, pow_ui, sinh, tan, tanh, ui_pow, ui_pow_ui
+- other new functions: mpfr_const_euler, mpfr_dim, mpfr_fma, mpfr_hypot,
+  mpfr_min, mpfr_max, mpfr_rint, mpfr_set_inf, mpfr_set_nan
+- new operations with MPZ or MPQ: mpfr_{add,sub,mul,div}_[zq]
+- new predicates: mpfr_inf_p, mpfr_nan_p, mpfr_number_p, mpfr_isinteger,
+- add mechanism to set/check exponent range (overflow, underflow), partially
+  implemented in the mpfr functions.
+- efficiency: mpfr_div is now faster when the divisor has a few limbs
+- rounding: now mpfr_pow implements exact rounding, and most functions return a
+  ternary value indicating the position of the returned value wrt the exact one
+  (thus the return value is now 'int' instead of 'void')
+- complete rewrite of the configuration files
+- mpfr_get_d, mpfr_{add,sub}_one_ulp now get a rounding mode as 2nd argument
+- some function names did change: mpz_set_fr is now mpfr_get_z_exp,
+  mpfr_print_raw is now mpfr_print_binary.
+
+Changes from version 1.0 to version 2001:
+- the default installation does not provide any more access to machine
+  rounding mode, and as a consequence does not compare MPFR results with
+  precision=53 to machine results. Add option -DTEST if you want to have
+  access to machine rounding mode, and to check MPFR results against.
+- the MPFR files do not need <math.h> any more
+- the header file <mpfr.h> was split into <mpfr.h> for exported functions
+  and <mpfr-impl.h> for internal functions. The user should not use functions
+  or macros from <mpfr-impl.h>, since those may change in further releases.
+- <mpfr.h> was modified in order to make easy a C++ interface
+- MPFR now deals with infinities (+infinity and -infinity) and NaN
+- the missing function mpfr_swap is now available
+- mpfr_zeta was removed (was incomplete)
+- mpfr_init and mpfr_init2 now initialize the corresponding variable to 0
+  (like in other initialization functions from GNU MP)
+- in case memory allocation fails, an error message is output
+- several bugs of version 1.0 were fixed
+
+Changes from version 0.4 to version 1.0:
+
+- Version 1.0 now uses a standard configure/make installation.
+- Version 1.0 implements all functions that are available in the MPF class
+  from GMP 3.1 (except mpf_swap) and a header file mpf2mpfr.h is included in
+  the distribution for easy change from MPF to MPFR.
+- Version 1.0 implements new elementary functions: mpfr_sincos
+- Some functions and macros have been renamed: mpfr_log2 is now
+  mpfr_const_log2, mpfr_pi is now mpfr_const_pi, SIGN is now MPFR_SIGN.
+- Version 1.0 uses faster algorithms for mpfr_exp, mpfr_const_pi,
+  mpfr_const_log2. Compare the timings from version 1.0 and version 0.4.
+- Version 1.0 corrects some bugs of version 0.4.
+- The precision of MPFR variables is now named mpfr_prec, which makes it
+  easier to change it, to say unsigned long long. Same for the rounding mode
+  which is called mp_rnd_t.
+
+You'll find other news concerning the GNU MPFR library on the web
+page <http://www.mpfr.org/>.

+##############################################################################
+1. Documentation
+##############################################################################
+
+- add a description of the algorithms used + proof of correctness
+
+##############################################################################
+2. Installation
+##############################################################################
+
+- if we want to distinguish GMP and MPIR, we can check at configure time
+  the following symbols which are only defined in MPIR:
+
+  #define __MPIR_VERSION 0
+  #define __MPIR_VERSION_MINOR 9
+  #define __MPIR_VERSION_PATCHLEVEL 0
+
+  There is also a library symbol mpir_version, which should match VERSION, set
+  by configure, for example 0.9.0.
+
+##############################################################################
+3. Changes in existing functions
+##############################################################################
+
+- export mpfr_overflow and mpfr_underflow as public functions
+
+- many functions currently taking into account the precision of the *input*
+  variable to set the initial working precison (acosh, asinh, cosh, ...).
+  This is nonsense since the "average" working precision should only depend
+  on the precision of the *output* variable (and maybe on the *value* of
+  the input in case of cancellation).
+  -> remove those dependencies from the input precision.
+
+- mpfr_can_round:
+   change the meaning of the 2nd argument (err). Currently the error is
+   at most 2^(MPFR_EXP(b)-err), i.e. err is the relative shift wrt the
+   most significant bit of the approximation. I propose that the error
+   is now at most 2^err ulps of the approximation, i.e.
+   2^(MPFR_EXP(b)-MPFR_PREC(b)+err).
+
+- mpfr_set_q first tries to convert the numerator and the denominator
+  to mpfr_t. But this convertion may fail even if the correctly rounded
+  result is representable. New way to implement:
+  Function q = a/b.  nq = PREC(q) na = PREC(a) nb = PREC(b)
+    If na < nb
+       a <- a*2^(nb-na)
+    n <- na-nb+ (HIGH(a,nb) >= b)
+    if (n >= nq)
+       bb <- b*2^(n-nq)
+       a  = q*bb+r     --> q has exactly n bits.
+    else
+       aa <- a*2^(nq-n)
+       aa = q*b+r      --> q has exactly n bits.
+  If RNDN, takes nq+1 bits. (See also the new division function).
+
+
+##############################################################################
+4. New functions to implement
+##############################################################################
+
+- implement mpfr_q_sub, mpfr_z_div, mpfr_q_div?
+- implement functions for random distributions, see for example
+  https://sympa.inria.fr/sympa/arc/mpfr/2010-01/msg00034.html
+  (suggested by Charles Karney <ckarney@Sarnoff.com>, 18 Jan 2010):
+   * a Bernoulli distribution with prob p/q (exact)
+   * a general discrete distribution (i with prob w[i]/sum(w[i]) (Walker
+     algorithm, but make it exact)
+   * a uniform distribution in (a,b)
+   * exponential distribution (mean lambda) (von Neumann's method?)
+   * normal distribution (mean m, s.d. sigma) (ratio method?)

+5. Efficiency
+##############################################################################
+
+- implement a mpfr_sqrthigh algorithm based on Mulders' algorithm, with a
+  basecase variant
+- use mpn_div_q to speed up mpfr_div. However mpn_div_q, which is new in
+  GMP 5, is not documented in the GMP manual, thus we are not sure it
+  guarantees to return the same quotient as mpn_tdiv_qr.
+  Also mpfr_div uses the remainder computed by mpn_divrem. A workaround would
+  be to first try with mpn_div_q, and if we cannot (easily) compute the
+  rounding, then use the current code with mpn_divrem.
+- compute exp by using the series for cosh or sinh, which has half the terms
+  (see Exercise 4.11 from Modern Computer Arithmetic, version 0.3)
+  The same method can be used for log, using the series for atanh, i.e.,
+  atanh(x) = 1/2*log((1+x)/(1-x)).
+- improve mpfr_gamma (see http://code.google.com/p/fastfunlib/). A possible
+  idea is to implement a fast algorithm for the argument reconstruction
+  gamma(x+k). One could also use the series for 1/gamma(x), see for example
+  http://dlmf.nist.gov/5/7/ or formula (36) from
+  http://mathworld.wolfram.com/GammaFunction.html
+- fix regression with mpfr_mpz_root (from Keith Briggs, 5 July 2006), for
+   example on 3Ghz P4 with gmp-4.2, x=12.345:
+   prec=50000    k=2   k=3   k=10  k=100
+   mpz_root      0.036 0.072 0.476 7.628
+   mpfr_mpz_root 0.004 0.004 0.036 12.20
+   See also mail from Carl Witty on mpfr list, 09 Oct 2007.
+- implement Mulders algorithm for squaring and division
+- for sparse input (say x=1 with 2 bits), mpfr_exp is not faster than for
+        full precision when precision <= MPFR_EXP_THRESHOLD. The reason is
+        that argument reduction kills sparsity. Maybe avoid argument reduction
+        for sparse input?
+- speed up const_euler for large precision [for x=1.1, prec=16610, it takes
+        75% of the total time of eint(x)!]
+- speed up mpfr_atan for large arguments (to speed up mpc_log)
+        [from Mark Watkins on Fri, 18 Mar 2005]
+  Also mpfr_atan(x) seems slower (by a factor of 2) for x near from 1.
+  Example on a Athlon for 10^5 bits: x=1.1 takes 3s, whereas 2.1 takes 1.8s.
+  The current implementation does not give monotonous timing for the following:
+  mpfr_random (x); for (i = 0; i < k; i++) mpfr_atan (y, x, MPFR_RNDN);
+  for precision 300 and k=1000, we get 1070ms, and 500ms only for p=400!
+- improve mpfr_sin on values like ~pi (do not compute sin from cos, because
+  of the cancellation). For instance, reduce the input modulo pi/2 in
+  [-pi/4,pi/4], and define auxiliary functions for which the argument is
+  assumed to be already reduced (so that the sin function can avoid
+  unnecessary computations by calling the auxiliary cos function instead of
+  the full cos function). This will require a native code for sin, for
+  example using the reduction sin(3x)=3sin(x)-4sin(x)^3.
+  See https://sympa.inria.fr/sympa/arc/mpfr/2007-08/msg00001.html and
+  the following messages.
+- improve generic.c to work for number of terms <> 2^k
+- rewrite mpfr_greater_p... as native code.
+
+- mpf_t uses a scheme where the number of limbs actually present can
+  be less than the selected precision, thereby allowing low precision
+  values (for instance small integers) to be stored and manipulated in
+  an mpf_t efficiently.
+
+  Perhaps mpfr should get something similar, especially if looking to
+  replace mpf with mpfr, though it'd be a major change.  Alternately
+  perhaps those mpfr routines like mpfr_mul where optimizations are
+  possible through stripping low zero bits or limbs could check for
+  that (this would be less efficient but easier).
+
+- try the idea of the paper "Reduced Cancellation in the Evaluation of Entire
+  Functions and Applications to the Error Function" by W. Gawronski, J. Mueller
+  and M. Reinhard, to be published in SIAM Journal on Numerical Analysis: to
+  avoid cancellation in say erfc(x) for x large, they compute the Taylor
+  expansion of erfc(x)*exp(x^2/2) instead (which has less cancellation),
+  and then divide by exp(x^2/2) (which is simpler to compute).
+
+- replace the *_THRESHOLD macros by global (TLS) variables that can be
+  changed at run time (via a function, like other variables)? One benefit
+  is that users could use a single MPFR binary on several machines (e.g.,
+  a library provided by binary packages or shared via NFS) with different
+  thresholds. On the default values, this would be a bit less efficient
+  than the current code, but this isn't probably noticeable (this should
+  be tested). Something like:
+    long *mpfr_tune_get(void) to get the current values (the first value
+      is the size of the array).
+    int mpfr_tune_set(long *array) to set the tune values.
+    int mpfr_tune_run(long level) to find the best values (the support
+      for this feature is optional, this can also be done with an
+      external function).
+
+- better distinguish different processors (for example Opteron and Core 2)
+  and use corresponding default tuning parameters (as in GMP). This could be
+  done in configure.ac to avoid hacking config.guess, for example define
+  MPFR_HAVE_CORE2.
+  Note (VL): the effect on cross-compilation (that can be a processor
+  with the same architecture, e.g. compilation on a Core 2 for an
+  Opteron) is not clear. The choice should be consistent with the
+  build target (e.g. -march or -mtune value with gcc).
+  Also choose better default values. For instance, the default value of
+  MPFR_MUL_THRESHOLD is 40, while the best values that have been found
+  are between 11 and 19 for 32 bits and between 4 and 10 for 64 bits!
+
+- during the Many Digits competition, we noticed that (our implantation of)
+  Mulders short product was slower than a full product for large sizes.
+  This should be precisely analyzed and fixed if needed.

+- check the constants mpfr_set_emin (-16382-63) and mpfr_set_emax (16383) in
+  get_ld.c and the other constants, and provide a testcase for large and
+  small numbers.
+
+- from Kevin Ryde <user42@zip.com.au>:
+   Also for pi.c, a pre-calculated compiled-in pi to a few thousand
+   digits would be good value I think.  After all, say 10000 bits using
+   1250 bytes would still be small compared to the code size!
+   Store pi in round to zero mode (to recover other modes).
+
+- add a new rounding mode: round to nearest, with ties away from zero
+  (this is roundTiesToAway in 754-2008, could be used by mpfr_round)
+- add a new roundind mode: round to odd. If the result is not exactly
+        representable, then round to the odd mantissa. This rounding
+        has the nice property that for k > 1, if:
+        y = round(x, p+k, TO_ODD)
+        z = round(y, p, TO_NEAREST_EVEN), then
+        z = round(x, p, TO_NEAREST_EVEN)
+  so it avoids the double-rounding problem.
+
+- add tests of the ternary value for constants
+
+- When doing Extensive Check (--enable-assert=full), since all the
+  functions use a similar use of MACROS (ZivLoop, ROUND_P), it should
+  be possible to do such a scheme:
+    For the first call to ROUND_P when we can round.
+    Mark it as such and save the approximated rounding value in
+    a temporary variable.
+    Then after, if the mark is set, check if:
+      - we still can round.
+      - The rounded value is the same.
+  It should be a complement to tgeneric tests.
+
+- in div.c, try to find a case for which cy != 0 after the line
+        cy = mpn_sub_1 (sp + k, sp + k, qsize, cy);
+  (which should be added to the tests), e.g. by having {vp, k} = 0, or
+  prove that this cannot happen.
+
+- add a configure test for --enable-logging to ignore the option if
+  it cannot be supported. Modify the "configure --help" description
+  to say "on systems that support it".
+
+- add generic bad cases for functions that don't have an inverse
+  function that is implemented (use a single Newton iteration).
+
+- add bad cases for the internal error bound (by using a dichotomy
+  between a bad case for the correct rounding and some input value
+  with fewer Ziv iterations?).
+
+- add an option to use a 32-bit exponent type (int) on LP64 machines,
+  mainly for developers, in order to be able to test the case where the
+  extended exponent range is the same as the default exponent range, on
+  such platforms.
+  Tests can be done with the exp-int branch (added on 2010-12-17, and
+  many tests fail at this time).
+
+- test underflow/overflow detection of various functions (in particular
+  mpfr_exp) in reduced exponent ranges, including ranges that do not
+  contain 0.
+
+- add an internal macro that does the equivalent of the following?
+    MPFR_IS_ZERO(x) || MPFR_GET_EXP(x) <= value
+
+- check whether __gmpfr_emin and __gmpfr_emax could be replaced by
+  a constant (see README.dev). Also check the use of MPFR_EMIN_MIN
+  and MPFR_EMAX_MAX.
+
+

+- [Kevin about texp.c long strings]
+  For strings longer than c99 guarantees, it might be cleaner to
+  introduce a "tests_strdupcat" or something to concatenate literal
+  strings into newly allocated memory.  I thought I'd done that in a

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory.  The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH.  The drawback is that using absolute paths prevent a

+\`configure' configures MPFR 3.1.2 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:

+  --with-sysroot=DIR Search for dependent libraries within DIR
+                        (or the compiler's sysroot if not specified).
+
+Some influential environment variables:
+  CC          C compiler command
+  CFLAGS      C compiler flags
+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
+              nonstandard directory <lib dir>
+  LIBS        libraries to pass to the linker, e.g. -l<library>
+  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+              you have headers in a nonstandard directory <include dir>
+  CPP         C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+##   up in a subdir.  Having to rename by hand is ugly.
+##   (We might end up doing this anyway to support other compilers.)

+##   -MM, not -M (despite what the docs say).
+## - Using -M directly means running the compiler twice (even worse

+<dt id="mpfr_vs_mpf">1. What are the differences between
+<cite><acronym>MPF</acronym></cite> from <cite><acronym>GMP</acronym></cite>
+and <cite><acronym>MPFR</acronym></cite>?</dt>
+
+<dd><p>The main differences are:</p>
+<ul>
+<li><p>The precision of a <cite><acronym>MPFR</acronym></cite> variable
+is the <em>exact</em> number of bits used for its mantissa, whereas in
+<cite><acronym>MPF</acronym></cite>, the precision requested by the user
+is a minimum value (<cite><acronym>MPF</acronym></cite> generally uses a
+higher precision). With the additional difference below, this implies that
+the <cite><acronym>MPFR</acronym></cite> results do not depend on the
+number of bits (16, 32, 64 or more) of the underlying architecture.</p></li>
+<li><p>As a consequence, <cite><acronym>MPFR</acronym></cite> uses a
+base-2 exponent, whereas in <cite><acronym>MPF</acronym></cite>, this
+is a base-2<sup>32</sup> or base-2<sup>64</sup> exponent, depending on
+the limb size. For this reason (and other internal ones), the maximum
+exponent range in <cite><acronym>MPFR</acronym></cite> is different
+(and smaller, if the exponent is represented by the same type as in
+<cite><acronym>MPF</acronym></cite>).</p></li>
+<li><p><cite><acronym>MPFR</acronym></cite> provides an additional rounding
+mode argument to its functions; furthermore, it is guaranteed that the
+result of any operation is the nearest possible floating-point value from
+the exact result (considering the input variables as exact values), taking
+into account the precision of the destination variable and the rounding
+mode. <cite><acronym>MPFR</acronym></cite> also says whether the rounded
+result is above or below the exact result.</p></li>
+<li><p><cite><acronym>MPFR</acronym></cite> supports much more functions
+(in particular transcendental functions such as exponentials, logarithms,
+trigonometric functions and so on) and special values: signed zeros,
+infinities, not-a-number (NaN).</p></li>
+</ul></dd>
+
+<dt id="mpf2mpfr">2. How to convert my program written using
+<cite><acronym>MPF</acronym></cite> to
+<cite><acronym>MPFR</acronym></cite>?</dt>
+
+<dd><p>You need to add <q><code>r</code></q> to the function names, and to
+specify the rounding mode (<code>MPFR_RNDN</code> for rounding to nearest,
+<code>MPFR_RNDZ</code> for rounding toward zero, <code>MPFR_RNDU</code>
+for rounding toward plus infinity, <code>MPFR_RNDD</code> for rounding
+toward minus infinity). You can also define macros as follows:
+<code class="block-code">#define mpf_add(a, b, c) mpfr_add(a, b, c, MPFR_RNDN)</code></p>
+<p>The header file <samp>mpf2mpfr.h</samp> from the
+<cite><acronym>MPFR</acronym></cite> distribution automatically
+redefines all <cite><acronym>MPF</acronym></cite> functions in this
+way, using the default <cite><acronym>MPFR</acronym></cite> rounding
+mode. Thus you simply need to add the following line in all your files
+using <cite><acronym>MPF</acronym></cite> functions:
+<code class="block-code">#include &lt;mpf2mpfr.h&gt;</code>
+just after the <samp>gmp.h</samp> and <samp>mpfr.h</samp>
+header files. If the program uses <cite><acronym>MPF</acronym></cite>
+internals (such as direct access to <code>__mpf_struct</code> members),
+additional changes will be needed.</p></dd>
+
+<dt id="no_libgmp">3. At configure time, I get the error: <q>libgmp not found or uses a different ABI.</q></dt>
+
+<dd><p>This test (<samp>checking for __gmpz_init in -lgmp</samp>) comes
+after the <samp>gmp.h</samp> detection. The failure occurs either because
+the <cite><acronym>GMP</acronym></cite> library could not be found
+(as it is not in the provided library search paths) or because the
+<cite><acronym>GMP</acronym></cite> library that was found does not have
+the expected <acronym title="Application Binary Interface">ABI</acronym>
+(<abbr>e.g.</abbr> 32-bit <abbr>vs</abbr> 64-bit). The former problem can be
+due to the fact that a static build of <cite><acronym>MPFR</acronym></cite>
+was requested while only a shared <cite><acronym>GMP</acronym></cite> library
+is installed (or the opposite, but another error can also show up in this
+case, see the <a href="#fpic">question about <samp>-fPIC</samp></a>). The
+latter problem can have several causes:</p>
+<ul>
+<li>A wrong libgmp library has been picked up. This can occur if you have
+several <cite><acronym>GMP</acronym></cite> versions installed on the
+machine and something is wrong with the provided library search paths.</li>
+<li>Wrong compiler options (<samp>CFLAGS</samp>) were given. In general, the
+presence or absence of the <samp>-m64</samp> compiler option must match the
+library <acronym title="Application Binary Interface">ABI</acronym>.</li>
+<li>A wrong <samp>gmp.h</samp> file has been picked up (if you have several
+<cite><acronym>GMP</acronym></cite> versions installed). Indeed, by default,
+<cite><acronym>MPFR</acronym></cite> gets the compiler options from the
+<samp>gmp.h</samp> file (with <cite><acronym>GMP</acronym></cite> 4.2.3
+or later); this is needed because <cite><acronym>GMP</acronym></cite> does
+not necessarily use the default <acronym>ABI</acronym>. The consequence is
+that if the <samp>gmp.h</samp> file is associated with a library using a
+different <acronym>ABI</acronym>, the <acronym>ABI</acronym>-related options
+will be incorrect. Hence the failure.</li>
+</ul>
+<p>Note: The <samp>config.log</samp> output gives more information
+than the error message. In particular, see the output of the test:
+<samp>checking for CC and CFLAGS in gmp.h</samp>; it should give you
+the default compiler options (from <samp>gmp.h</samp>).</p>
+
+<p>See also the answer to the <a href="#undef_ref1">next question</a>.</p></dd>
+
+<dt id="undef_ref1">4. I get undefined reference to <code>__gmp_get_memory_functions</code>.</dt>
+
+<dd><p>Note: this was mainly a problem when upgrading from
+<cite><acronym>GMP</acronym></cite> 4.1.4 to a later version,
+but information given below may still be useful in other cases,
+when several <cite><acronym>GMP</acronym></cite> libraries are
+installed on the same machine.</p>
+
+<p>If you get such an error, in particular when running
+<samp>make check</samp>, then this probably means that you are using
+the header file from <cite><acronym>GMP</acronym></cite> 4.2.x but the
+<cite><acronym>GMP</acronym></cite> 4.1.4 library. This can happen if
+several <cite><acronym>GMP</acronym></cite> versions are installed on
+your machine (<abbr>e.g.</abbr>, one provided by the system in
+<samp>/usr/{include,lib}</samp> and a new one installed by the owner or
+administrator of the machine in <samp>/usr/local/{include,lib}</samp>)
+and your include and library search paths are inconsistent. On various
+<acronym>GNU</acronym>/Linux machines, this is unfortunately the case
+by default (<samp>/usr/local/include</samp> is in the default include
+search path, but <samp>/usr/local/lib</samp> is <em>not</em> in the
+default library search path). Typical errors are:
+<samp class="block-code">undefined reference to `__gmp_get_memory_functions'</samp>
+in <samp>make check</samp>. The best solution is to add
+<samp>/usr/local/include</samp> to your <var class="env">C_INCLUDE_PATH</var>
+environment variable and to add <samp>/usr/local/lib</samp> to your
+<var class="env">LIBRARY_PATH</var> and <var class="env">LD_LIBRARY_PATH</var>
+environment variables (and/or <var class="env">LD_RUN_PATH</var>).
+Alternatively, you can use <samp>--with-gmp*</samp> configure options,
+<abbr>e.g.</abbr> <samp>--with-gmp=/usr/local</samp>, but <strong>this is
+not guaranteed to work</strong> (in particular with <samp>gcc</samp> and
+system directories such as <samp>/usr</samp> or <samp>/usr/local</samp>),
+and other software that uses <cite><acronym>GMP</acronym></cite> and/or
+<cite><acronym>MPFR</acronym></cite> will need correct paths too;
+environment variables allow you to set them in a global way.</p>
+<p>Other information can be given in the <samp>INSTALL</samp> file and
+<samp>ld</samp> manual. Please look at them for more details. See also
+the <a href="#undef_ref2">next question</a>.</p></dd>
+
+<dt id="undef_ref2">5. When I link my program with
+<cite><acronym>MPFR</acronym></cite>, I get undefined reference
+to <code>__gmpXXXX</code>.</dt>
+
+<dd><p>Link your program with <cite><acronym>GMP</acronym></cite>. Assuming
+that your program is <samp>foo.c</samp>, you should link it using:
+<samp class="block-code">cc link.c -lmpfr -lgmp</samp>
+<cite><acronym>MPFR</acronym></cite> library reference (<samp>-lmpfr</samp>)
+should be before <cite><acronym>GMP</acronym></cite>'s one
+(<samp>-lgmp</samp>). Another solution is, with <acronym>GNU</acronym>
+<samp>ld</samp>, to give all the libraries inside a group:
+<samp class="block-code">gcc link.c -Wl,--start-group libgmp.a libmpfr.a -Wl,--end-group</samp>
+See <samp>INSTALL</samp> file and <samp>ld</samp> manual for more
+details.</p>
+<p>If you used correct link options, but still get an error, this may mean
+that your include and library search paths are inconsistent. Please see the
+<a href="#undef_ref1">previous question</a>.</p></dd>
+
+<dt id="crash_high_prec">6. My program crashes with high precisions.</dt>
+
+<dd><p>Your stack size limit may be too small; indeed, by default,
+<cite><acronym>GMP</acronym></cite> 4.1.4 and below allocates all
+temporary results on the stack, and in very high precisions, this
+limit may be reached. You can solve this problem in different ways:</p>
+<ul>
+<li><p>You can upgrade to <cite><acronym>GMP</acronym></cite> 4.2 (or above),
+which now makes temporary allocations on the stack only when they are
+small.</p></li>
+<li><p>You can increase the stack size limit with the <samp>limit</samp>,
+<samp>unlimit</samp> or <samp>ulimit</samp> command, depending on your
+shell. This may fail on some systems, where the maximum stack size cannot
+be increased above some value.</p></li>
+<li><p>You can rebuild both <cite><acronym>GMP</acronym></cite> and
+<cite><acronym>MPFR</acronym></cite> to use another allocation method.</p></li>
+</ul></dd>
+
+<dt id="accuracy">7. Though I have increased the precision, the results
+are not more accurate.</dt>
+
+<dd><p>The reason may be the use of C floating-point numbers. If you want
+to store a floating-point constant to a <code>mpfr_t</code>, you should use
+<code>mpfr_set_str</code> (or one of the <cite><acronym>MPFR</acronym></cite>
+constant functions, such as <code>mpfr_const_pi</code> for &#960;) instead
+of <code>mpfr_set_d</code> or <code>mpfr_set_ld</code>. Otherwise the
+floating-point constant will be first converted into a reduced-precision
+(<abbr>e.g.</abbr>, 53-bit) binary number before
+<cite><acronym>MPFR</acronym></cite> can work with it. This is the case
+in particular for most exact decimal numbers, such as 0.17, which are
+not exactly representable in binary.</p>
+<p>Also remember that <cite><acronym>MPFR</acronym></cite> does not track
+the accuracy of the results: copying a value <var>x</var> to <var>y</var>
+with <code>mpfr_set (y, x, MPFR_RNDN)</code> where the variable <var>y</var>
+is more precise than the variable <var>x</var> will not make it more
+accurate; the (binary) value will remain unchanged.</p></dd>
+
+<dt id="detect_mpfr">8. How can I detect <cite><acronym>MPFR</acronym></cite>
+installation using <cite>autoconf</cite> or <cite>pkg-config</cite>?</dt>
+
+<dd><p>The <cite><acronym>MPFR</acronym></cite> team does not currently
+recommend any <cite>autoconf</cite> code, but a section will later
+be added to the <cite><acronym>MPFR</acronym></cite> manual. The
+<cite><acronym>MPFR</acronym></cite> team does not wish to support
+<cite>pkg-config</cite> yet.</p></dd>
+
+<dt id="cite">9. How to cite <cite><acronym>MPFR</acronym></cite> in a
+scientific publication?</dt>
+
+<dd><p>To properly cite <cite><acronym>MPFR</acronym></cite> in a scientific
+publication, please cite the
+<a href="http://doi.acm.org/10.1145/1236463.1236468"><acronym title="Association for Computing Machinery">ACM</acronym>
+<acronym title="Transactions on Mathematical Software">TOMS</acronym>
+paper</a>
+(<a href="http://toms.acm.org/cgi/TOMSbibget.cgi?Fousse:2007:MMP">BibTeX</a>)
+and/or the library web page
+<a href="http://www.mpfr.org/">http://www.mpfr.org</a>. If your publication
+is related to a particular release of <cite><acronym>MPFR</acronym></cite>,
+for example if you report timings, please also indicate the release number
+for future reference.</p></dd>
+
+<dt id="fpic">10. When I build <cite><acronym>MPFR</acronym></cite>, I get
+an error asking me to recompile with <samp>-fPIC</samp>.</dt>
+
+<dd><p>A typical error looks like:</p>
+<p><tt>/usr/bin/ld: <em>/path/to/</em>libgmp.a(realloc.o): relocation
+R_X86_64_32 against `.rodata.str1.1' can not be used when making a
+shared object; recompile with -fPIC<br />
+<em>/path/to/</em>libgmp.a: could not read symbols: Bad value<br />
+collect2: ld returned 1 exit status</tt></p>
+<p>The probable reason is that you tried to build
+<cite><acronym>MPFR</acronym></cite> with the shared library enabled (this
+is the default), while only a static <cite><acronym>GMP</acronym></cite>
+library could be found. To solve this problem, either rebuild and reinstall
+<cite><acronym>GMP</acronym></cite> without the <samp>--disable-shared</samp>
+configure option, or configure <cite><acronym>MPFR</acronym></cite> with
+<samp>--disable-shared</samp>. If you did this and still get the above
+error, the cause may be conflicting <cite><acronym>GMP</acronym></cite>
+versions installed on your system; please check that your search path
+settings are correct.</p>
+<p>Additional note about the last sentence: Under <acronym>GNU</acronym>/Linux
+(for instance), the linker takes the first library found in the library search
+path, whether it is dynamic or static. The default behavior under darwin is
+different, but <cite><acronym>MPFR</acronym></cite> will change it.</p></dd>

+Copyright @copyright{} 2000,2001,2002 Free Software Foundation, Inc.
+51 Franklin St, Fifth Floor, Boston, MA  02110-1301, USA
+
+Everyone is permitted to copy and distribute verbatim copies
+of this license document, but changing it is not allowed.
+@end display
+
+@enumerate 0
+@item
+PREAMBLE
+
+The purpose of this License is to make a manual, textbook, or other
+functional and useful document @dfn{free} in the sense of freedom: to
+assure everyone the effective freedom to copy and redistribute it,
+with or without modifying it, either commercially or noncommercially.
+Secondarily, this License preserves for the author and publisher a way
+to get credit for their work, while not being considered responsible
+for modifications made by others.
+
+This License is a kind of ``copyleft'', which means that derivative
+works of the document must themselves be free in the same sense.  It
+complements the GNU General Public License, which is a copyleft
+license designed for free software.
+
+We have designed this License in order to use it for manuals for free
+software, because free software needs free documentation: a free
+program should come with manuals providing the same freedoms that the
+software does.  But this License is not limited to software manuals;
+it can be used for any textual work, regardless of subject matter or
+whether it is published as a printed book.  We recommend this License
+principally for works whose purpose is instruction or reference.
+
+@item
+APPLICABILITY AND DEFINITIONS
+
+This License applies to any manual or other work, in any medium, that
+contains a notice placed by the copyright holder saying it can be
+distributed under the terms of this License.  Such a notice grants a
+world-wide, royalty-free license, unlimited in duration, to use that
+work under the conditions stated herein.  The ``Document'', below,
+refers to any such manual or work.  Any member of the public is a
+licensee, and is addressed as ``you''.  You accept the license if you
+copy, modify or distribute the work in a way requiring permission
+under copyright law.
+
+A ``Modified Version'' of the Document means any work containing the
+Document or a portion of it, either copied verbatim, or with
+modifications and/or translated into another language.
+
+A ``Secondary Section'' is a named appendix or a front-matter section
+of the Document that deals exclusively with the relationship of the
+publishers or authors of the Document to the Document's overall
+subject (or to related matters) and contains nothing that could fall
+directly within that overall subject.  (Thus, if the Document is in
+part a textbook of mathematics, a Secondary Section may not explain
+any mathematics.)  The relationship could be a matter of historical
+connection with the subject or with related matters, or of legal,
+commercial, philosophical, ethical or political position regarding
+them.
+
+The ``Invariant Sections'' are certain Secondary Sections whose titles
+are designated, as being those of Invariant Sections, in the notice
+that says that the Document is released under this License.  If a
+section does not fit the above definition of Secondary then it is not
+allowed to be designated as Invariant.  The Document may contain zero
+Invariant Sections.  If the Document does not identify any Invariant
+Sections then there are none.
+
+The ``Cover Texts'' are certain short passages of text that are listed,
+as Front-Cover Texts or Back-Cover Texts, in the notice that says that
+the Document is released under this License.  A Front-Cover Text may
+be at most 5 words, and a Back-Cover Text may be at most 25 words.
+
+A ``Transparent'' copy of the Document means a machine-readable copy,
+represented in a format whose specification is available to the
+general public, that is suitable for revising the document
+straightforwardly with generic text editors or (for images composed of
+pixels) generic paint programs or (for drawings) some widely available
+drawing editor, and that is suitable for input to text formatters or
+for automatic translation to a variety of formats suitable for input
+to text formatters.  A copy made in an otherwise Transparent file
+format whose markup, or absence of markup, has been arranged to thwart
+or discourage subsequent modification by readers is not Transparent.
+An image format is not Transparent if used for any substantial amount
+of text.  A copy that is not ``Transparent'' is called ``Opaque''.
+
+Examples of suitable formats for Transparent copies include plain
+@sc{ascii} without markup, Texinfo input format, La@TeX{} input
+format, @acronym{SGML} or @acronym{XML} using a publicly available
+@acronym{DTD}, and standard-conforming simple @acronym{HTML},
+PostScript or @acronym{PDF} designed for human modification.  Examples
+of transparent image formats include @acronym{PNG}, @acronym{XCF} and
+@acronym{JPG}.  Opaque formats include proprietary formats that can be
+read and edited only by proprietary word processors, @acronym{SGML} or
+@acronym{XML} for which the @acronym{DTD} and/or processing tools are
+not generally available, and the machine-generated @acronym{HTML},
+PostScript or @acronym{PDF} produced by some word processors for
+output purposes only.
+
+The ``Title Page'' means, for a printed book, the title page itself,
+plus such following pages as are needed to hold, legibly, the material
+this License requires to appear in the title page.  For works in
+formats which do not have any title page as such, ``Title Page'' means
+the text near the most prominent appearance of the work's title,
+preceding the beginning of the body of the text.
+
+A section ``Entitled XYZ'' means a named subunit of the Document whose
+title either is precisely XYZ or contains XYZ in parentheses following
+text that translates XYZ in another language.  (Here XYZ stands for a
+specific section name mentioned below, such as ``Acknowledgements'',
+``Dedications'', ``Endorsements'', or ``History''.)  To ``Preserve the Title''
+of such a section when you modify the Document means that it remains a
+section ``Entitled XYZ'' according to this definition.
+
+The Document may include Warranty Disclaimers next to the notice which
+states that this License applies to the Document.  These Warranty
+Disclaimers are considered to be included by reference in this
+License, but only as regards disclaiming warranties: any other
+implication that these Warranty Disclaimers may have is void and has
+no effect on the meaning of this License.
+
+@item
+VERBATIM COPYING
+
+You may copy and distribute the Document in any medium, either
+commercially or noncommercially, provided that this License, the
+copyright notices, and the license notice saying this License applies
+to the Document are reproduced in all copies, and that you add no other
+conditions whatsoever to those of this License.  You may not use
+technical measures to obstruct or control the reading or further
+copying of the copies you make or distribute.  However, you may accept
+compensation in exchange for copies.  If you distribute a large enough
+number of copies you must also follow the conditions in section 3.
+
+You may also lend copies, under the same conditions stated above, and
+you may publicly display copies.
+
+@item
+COPYING IN QUANTITY
+
+If you publish printed copies (or copies in media that commonly have
+printed covers) of the Document, numbering more than 100, and the
+Document's license notice requires Cover Texts, you must enclose the
+copies in covers that carry, clearly and legibly, all these Cover
+Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
+the back cover.  Both covers must also clearly and legibly identify
+you as the publisher of these copies.  The front cover must present
+the full title with all words of the title equally prominent and
+visible.  You may add other material on the covers in addition.
+Copying with changes limited to the covers, as long as they preserve
+the title of the Document and satisfy these conditions, can be treated
+as verbatim copying in other respects.
+
+If the required texts for either cover are too voluminous to fit
+legibly, you should put the first ones listed (as many as fit
+reasonably) on the actual cover, and continue the rest onto adjacent
+pages.
+
+If you publish or distribute Opaque copies of the Document numbering
+more than 100, you must either include a machine-readable Transparent
+copy along with each Opaque copy, or state in or with each Opaque copy
+a computer-network location from which the general network-using
+public has access to download using public-standard network protocols
+a complete Transparent copy of the Document, free of added material.
+If you use the latter option, you must take reasonably prudent steps,
+when you begin distribution of Opaque copies in quantity, to ensure
+that this Transparent copy will remain thus accessible at the stated
+location until at least one year after the last time you distribute an
+Opaque copy (directly or through your agents or retailers) of that
+edition to the public.
+
+It is requested, but not required, that you contact the authors of the
+Document well before redistributing any large number of copies, to give
+them a chance to provide you with an updated version of the Document.
+
+@item
+MODIFICATIONS
+
+You may copy and distribute a Modified Version of the Document under
+the conditions of sections 2 and 3 above, provided that you release
+the Modified Version under precisely this License, with the Modified
+Version filling the role of the Document, thus licensing distribution
+and modification of the Modified Version to whoever possesses a copy
+of it.  In addition, you must do these things in the Modified Version:
+
+@enumerate A
+@item
+Use in the Title Page (and on the covers, if any) a title distinct
+from that of the Document, and from those of previous versions
+(which should, if there were any, be listed in the History section
+of the Document).  You may use the same title as a previous version
+if the original publisher of that version gives permission.
+
+@item
+List on the Title Page, as authors, one or more persons or entities
+responsible for authorship of the modifications in the Modified
+Version, together with at least five of the principal authors of the
+Document (all of its principal authors, if it has fewer than five),
+unless they release you from this requirement.
+
+@item
+State on the Title page the name of the publisher of the
+Modified Version, as the publisher.
+
+@item
+Preserve all the copyright notices of the Document.
+
+@item
+Add an appropriate copyright notice for your modifications
+adjacent to the other copyright notices.
+
+@item
+Include, immediately after the copyright notices, a license notice
+giving the public permission to use the Modified Version under the
+terms of this License, in the form shown in the Addendum below.
+
+@item
+Preserve in that license notice the full lists of Invariant Sections
+and required Cover Texts given in the Document's license notice.
+
+@item
+Include an unaltered copy of this License.
+
+@item
+Preserve the section Entitled ``History'', Preserve its Title, and add
+to it an item stating at least the title, year, new authors, and
+publisher of the Modified Version as given on the Title Page.  If
+there is no section Entitled ``History'' in the Document, create one
+stating the title, year, authors, and publisher of the Document as
+given on its Title Page, then add an item describing the Modified
+Version as stated in the previous sentence.
+
+@item
+Preserve the network location, if any, given in the Document for
+public access to a Transparent copy of the Document, and likewise
+the network locations given in the Document for previous versions
+it was based on.  These may be placed in the ``History'' section.
+You may omit a network location for a work that was published at
+least four years before the Document itself, or if the original
+publisher of the version it refers to gives permission.
+
+@item
+For any section Entitled ``Acknowledgements'' or ``Dedications'', Preserve
+the Title of the section, and preserve in the section all the
+substance and tone of each of the contributor acknowledgements and/or
+dedications given therein.
+
+@item
+Preserve all the Invariant Sections of the Document,
+unaltered in their text and in their titles.  Section numbers
+or the equivalent are not considered part of the section titles.
+
+@item
+Delete any section Entitled ``Endorsements''.  Such a section
+may not be included in the Modified Version.
+
+@item
+Do not retitle any existing section to be Entitled ``Endorsements'' or
+to conflict in title with any Invariant Section.
+
+@item
+Preserve any Warranty Disclaimers.
+@end enumerate
+
+If the Modified Version includes new front-matter sections or
+appendices that qualify as Secondary Sections and contain no material
+copied from the Document, you may at your option designate some or all
+of these sections as invariant.  To do this, add their titles to the
+list of Invariant Sections in the Modified Version's license notice.
+These titles must be distinct from any other section titles.
+
+You may add a section Entitled ``Endorsements'', provided it contains
+nothing but endorsements of your Modified Version by various
+parties---for example, statements of peer review or that the text has
+been approved by an organization as the authoritative definition of a
+standard.
+
+You may add a passage of up to five words as a Front-Cover Text, and a
+passage of up to 25 words as a Back-Cover Text, to the end of the list
+of Cover Texts in the Modified Version.  Only one passage of
+Front-Cover Text and one of Back-Cover Text may be added by (or
+through arrangements made by) any one entity.  If the Document already
+includes a cover text for the same cover, previously added by you or
+by arrangement made by the same entity you are acting on behalf of,
+you may not add another; but you may replace the old one, on explicit
+permission from the previous publisher that added the old one.
+
+The author(s) and publisher(s) of the Document do not by this License
+give permission to use their names for publicity for or to assert or
+imply endorsement of any Modified Version.
+
+@item
+COMBINING DOCUMENTS
+
+You may combine the Document with other documents released under this
+License, under the terms defined in section 4 above for modified
+versions, provided that you include in the combination all of the
+Invariant Sections of all of the original documents, unmodified, and
+list them all as Invariant Sections of your combined work in its
+license notice, and that you preserve all their Warranty Disclaimers.
+
+The combined work need only contain one copy of this License, and
+multiple identical Invariant Sections may be replaced with a single
+copy.  If there are multiple Invariant Sections with the same name but
+different contents, make the title of each such section unique by
+adding at the end of it, in parentheses, the name of the original
+author or publisher of that section if known, or else a unique number.
+Make the same adjustment to the section titles in the list of
+Invariant Sections in the license notice of the combined work.
+
+In the combination, you must combine any sections Entitled ``History''
+in the various original documents, forming one section Entitled
+``History''; likewise combine any sections Entitled ``Acknowledgements'',
+and any sections Entitled ``Dedications''.  You must delete all
+sections Entitled ``Endorsements.''
+
+@item
+COLLECTIONS OF DOCUMENTS
+
+You may make a collection consisting of the Document and other documents
+released under this License, and replace the individual copies of this
+License in the various documents with a single copy that is included in
+the collection, provided that you follow the rules of this License for
+verbatim copying of each of the documents in all other respects.
+
+You may extract a single document from such a collection, and distribute
+it individually under this License, provided you insert a copy of this
+License into the extracted document, and follow this License in all
+other respects regarding verbatim copying of that document.
+
+@item
+AGGREGATION WITH INDEPENDENT WORKS
+
+A compilation of the Document or its derivatives with other separate
+and independent documents or works, in or on a volume of a storage or
+distribution medium, is called an ``aggregate'' if the copyright
+resulting from the compilation is not used to limit the legal rights
+of the compilation's users beyond what the individual works permit.
+When the Document is included in an aggregate, this License does not
+apply to the other works in the aggregate which are not themselves
+derivative works of the Document.
+
+If the Cover Text requirement of section 3 is applicable to these
+copies of the Document, then if the Document is less than one half of
+the entire aggregate, the Document's Cover Texts may be placed on
+covers that bracket the Document within the aggregate, or the
+electronic equivalent of covers if the Document is in electronic form.
+Otherwise they must appear on printed covers that bracket the whole
+aggregate.
+
+@item
+TRANSLATION
+
+Translation is considered a kind of modification, so you may
+distribute translations of the Document under the terms of section 4.
+Replacing Invariant Sections with translations requires special
+permission from their copyright holders, but you may include
+translations of some or all Invariant Sections in addition to the
+original versions of these Invariant Sections.  You may include a
+translation of this License, and all the license notices in the
+Document, and any Warranty Disclaimers, provided that you also include
+the original English version of this License and the original versions
+of those notices and disclaimers.  In case of a disagreement between
+the translation and the original version of this License or a notice
+or disclaimer, the original version will prevail.
+
+If a section in the Document is Entitled ``Acknowledgements'',
+``Dedications'', or ``History'', the requirement (section 4) to Preserve
+its Title (section 1) will typically require changing the actual
+title.
+
+@item
+TERMINATION
+
+You may not copy, modify, sublicense, or distribute the Document except
+as expressly provided for under this License.  Any other attempt to
+copy, modify, sublicense or distribute the Document is void, and will
+automatically terminate your rights under this License.  However,
+parties who have received copies, or rights, from you under this
+License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+@item
+FUTURE REVISIONS OF THIS LICENSE
+
+The Free Software Foundation may publish new, revised versions
+of the GNU Free Documentation License from time to time.  Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.  See
+@uref{http://www.gnu.org/copyleft/}.
+
+Each version of the License is given a distinguishing version number.
+If the Document specifies that a particular numbered version of this
+License ``or any later version'' applies to it, you have the option of
+following the terms and conditions either of that specified version or
+of any later version that has been published (not as a draft) by the
+Free Software Foundation.  If the Document does not specify a version
+number of this License, you may choose any version ever published (not
+as a draft) by the Free Software Foundation.

+@appendixsec ADDENDUM: How to Use This License For Your Documents
+
+To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and
+license notices just after the title page:
+
+@smallexample
+@group
+  Copyright (C)  @var{year}  @var{your name}.
+  Permission is granted to copy, distribute and/or modify this document
+  under the terms of the GNU Free Documentation License, Version 1.2
+  or any later version published by the Free Software Foundation;
+  with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
+  Texts.  A copy of the license is included in the section entitled ``GNU
+  Free Documentation License''.
+@end group
+@end smallexample
+
+If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
+replace the ``with...Texts.'' line with this:
+
+@smallexample
+@group
+    with the Invariant Sections being @var{list their titles}, with
+    the Front-Cover Texts being @var{list}, and with the Back-Cover Texts
+    being @var{list}.
+@end group
+@end smallexample
+
+If you have Invariant Sections without Cover Texts, or some other
+combination of the three, merge those two alternatives to suit the
+situation.
+
+If your document contains nontrivial examples of program code, we
+recommend releasing these examples in parallel under your choice of
+free software license, such as the GNU General Public License,
+to permit their use in free software.

+
+1 Introduction to MPFR
+**********************
+
+MPFR is a portable library written in C for arbitrary precision
+arithmetic on floating-point numbers. It is based on the GNU MP library.
+It aims to provide a class of floating-point numbers with precise
+semantics. The main characteristics of MPFR, which make it differ from
+most arbitrary precision floating-point software tools, are:
+
+   * the MPFR code is portable, i.e., the result of any operation does
+     not depend on the machine word size `mp_bits_per_limb' (64 on most
+     current processors);
+
+   * the precision in bits can be set _exactly_ to any valid value for
+     each variable (including very small precision);
+
+   * MPFR provides the four rounding modes from the IEEE 754-1985
+     standard, plus away-from-zero, as well as for basic operations as
+     for other mathematical functions.
+
+   In particular, with a precision of 53 bits, MPFR is able to exactly
+reproduce all computations with double-precision machine floating-point
+numbers (e.g., `double' type in C, with a C implementation that
+rigorously follows Annex F of the ISO C99 standard and `FP_CONTRACT'
+pragma set to `OFF') on the four arithmetic operations and the square
+root, except the default exponent range is much wider and subnormal
+numbers are not implemented (but can be emulated).
+
+   This version of MPFR is released under the GNU Lesser General Public
+License, version 3 or any later version.  It is permitted to link MPFR
+to most non-free programs, as long as when distributing them the MPFR
+source code and a means to re-link with a modified MPFR library is
+provided.
+
+1.1 How to Use This Manual
+==========================
+
+Everyone should read *note MPFR Basics::.  If you need to install the
+library yourself, you need to read *note Installing MPFR::, too.  To
+use the library you will need to refer to *note MPFR Interface::.
+
+   The rest of the manual can be used for later reference, although it
+is probably a good idea to glance through it.

+
+2 Installing MPFR
+*****************
+
+The MPFR library is already installed on some GNU/Linux distributions,
+but the development files necessary to the compilation such as `mpfr.h'
+are not always present. To check that MPFR is fully installed on your
+computer, you can check the presence of the file `mpfr.h' in
+`/usr/include', or try to compile a small program having `#include
+<mpfr.h>' (since `mpfr.h' may be installed somewhere else). For
+instance, you can try to compile:
+
+     #include <stdio.h>
+     #include <mpfr.h>
+     int main (void)
+     {
+       printf ("MPFR library: %-12s\nMPFR header:  %s (based on %d.%d.%d)\n",
+               mpfr_get_version (), MPFR_VERSION_STRING, MPFR_VERSION_MAJOR,
+               MPFR_VERSION_MINOR, MPFR_VERSION_PATCHLEVEL);
+       return 0;
+     }
+
+with
+
+     cc -o version version.c -lmpfr -lgmp
+
+and if you get errors whose first line looks like
+
+     version.c:2:19: error: mpfr.h: No such file or directory
+
+then MPFR is probably not installed. Running this program will give you
+the MPFR version.
+
+   If MPFR is not installed on your computer, or if you want to install
+a different version, please follow the steps below.
+
+2.1 How to Install
+==================
+
+Here are the steps needed to install the library on Unix systems (more
+details are provided in the `INSTALL' file):
+
+  1. To build MPFR, you first have to install GNU MP (version 4.1 or
+     higher) on your computer.  You need a C compiler, preferably GCC,
+     but any reasonable compiler should work.  And you need the
+     standard Unix `make' command, plus some other standard Unix
+     utility commands.
+
+     Then, in the MPFR build directory, type the following commands.
+
+  2. `./configure'
+
+     This will prepare the build and setup the options according to
+     your system.  You can give options to specify the install
+     directories (instead of the default `/usr/local'), threading
+     support, and so on. See the `INSTALL' file and/or the output of
+     `./configure --help' for more information, in particular if you
+     get error messages.
+
+  3. `make'
+
+     This will compile MPFR, and create a library archive file
+     `libmpfr.a'.  On most platforms, a dynamic library will be
+     produced too.
+
+  4. `make check'
+
+     This will make sure MPFR was built correctly.  If you get error
+     messages, please report this to the MPFR mailing-list
+     `mpfr@inria.fr'.  (*Note Reporting Bugs::, for information on what
+     to include in useful bug reports.)
+
+  5. `make install'
+
+     This will copy the files `mpfr.h' and `mpf2mpfr.h' to the directory
+     `/usr/local/include', the library files (`libmpfr.a' and possibly
+     others) to the directory `/usr/local/lib', the file `mpfr.info' to
+     the directory `/usr/local/share/info', and some other documentation
+     files to the directory `/usr/local/share/doc/mpfr' (or if you
+     passed the `--prefix' option to `configure', using the prefix
+     directory given as argument to `--prefix' instead of `/usr/local').
+
+2.2 Other `make' Targets
+========================
+
+There are some other useful make targets:
+
+   * `mpfr.info' or `info'
+
+     Create or update an info version of the manual, in `mpfr.info'.
+
+     This file is already provided in the MPFR archives.
+
+   * `mpfr.pdf' or `pdf'
+
+     Create a PDF version of the manual, in `mpfr.pdf'.
+
+   * `mpfr.dvi' or `dvi'
+
+     Create a DVI version of the manual, in `mpfr.dvi'.
+
+   * `mpfr.ps' or `ps'
+
+     Create a Postscript version of the manual, in `mpfr.ps'.
+
+   * `mpfr.html' or `html'
+
+     Create a HTML version of the manual, in several pages in the
+     directory `doc/mpfr.html'; if you want only one output HTML file,
+     then type `makeinfo --html --no-split mpfr.texi' from the `doc'
+     directory instead.
+
+   * `clean'
+
+     Delete all object files and archive files, but not the
+     configuration files.
+
+   * `distclean'
+
+     Delete all generated files not included in the distribution.
+
+   * `uninstall'
+
+     Delete all files copied by `make install'.
+
+2.3 Build Problems
+==================
+
+In case of problem, please read the `INSTALL' file carefully before
+reporting a bug, in particular section "In case of problem".  Some
+problems are due to bad configuration on the user side (not specific to
+MPFR). Problems are also mentioned in the FAQ
+`http://www.mpfr.org/faq.html'.
+
+   Please report problems to the MPFR mailing-list `mpfr@inria.fr'.
+*Note Reporting Bugs::.  Some bug fixes are available on the MPFR 3.1.2
+web page `http://www.mpfr.org/mpfr-3.1.2/'.
+
+2.4 Getting the Latest Version of MPFR
+======================================
+
+The latest version of MPFR is available from
+`ftp://ftp.gnu.org/gnu/mpfr/' or `http://www.mpfr.org/'.

+
+3 Reporting Bugs
+****************
+
+If you think you have found a bug in the MPFR library, first have a look
+on the MPFR 3.1.2 web page `http://www.mpfr.org/mpfr-3.1.2/' and the
+FAQ `http://www.mpfr.org/faq.html': perhaps this bug is already known,
+in which case you may find there a workaround for it.  You might also
+look in the archives of the MPFR mailing-list:
+`https://sympa.inria.fr/sympa/arc/mpfr'.  Otherwise, please investigate
+and report it.  We have made this library available to you, and it is
+not to ask too much from you, to ask you to report the bugs that you
+find.
+
+   There are a few things you should think about when you put your bug
+report together.
+
+   You have to send us a test case that makes it possible for us to
+reproduce the bug, i.e., a small self-content program, using no other
+library than MPFR.  Include instructions on how to run the test case.
+
+   You also have to explain what is wrong; if you get a crash, or if
+the results you get are incorrect and in that case, in what way.
+
+   Please include compiler version information in your bug report. This
+can be extracted using `cc -V' on some machines, or, if you're using
+GCC, `gcc -v'. Also, include the output from `uname -a' and the MPFR
+version (the GMP version may be useful too).  If you get a failure
+while running `make' or `make check', please include the `config.log'
+file in your bug report.
+
+   If your bug report is good, we will do our best to help you to get a
+corrected version of the library; if the bug report is poor, we will
+not do anything about it (aside of chiding you to send better bug
+reports).
+
+   Send your bug report to the MPFR mailing-list `mpfr@inria.fr'.
+
+   If you think something in this manual is unclear, or downright
+incorrect, or if the language needs to be improved, please send a note
+to the same address.

+
+4.1 Headers and Libraries
+=========================
+
+All declarations needed to use MPFR are collected in the include file
+`mpfr.h'.  It is designed to work with both C and C++ compilers.  You
+should include that file in any program using the MPFR library:
+
+     #include <mpfr.h>
+
+   Note however that prototypes for MPFR functions with `FILE *'
+parameters are provided only if `<stdio.h>' is included too (before
+`mpfr.h'):
+
+     #include <stdio.h>
+     #include <mpfr.h>
+
+   Likewise `<stdarg.h>' (or `<varargs.h>') is required for prototypes
+with `va_list' parameters, such as `mpfr_vprintf'.
+
+   And for any functions using `intmax_t', you must include
+`<stdint.h>' or `<inttypes.h>' before `mpfr.h', to allow `mpfr.h' to
+define prototypes for these functions. Moreover, users of C++ compilers
+under some platforms may need to define `MPFR_USE_INTMAX_T' (and should
+do it for portability) before `mpfr.h' has been included; of course, it
+is possible to do that on the command line, e.g., with
+`-DMPFR_USE_INTMAX_T'.
+
+   Note: If `mpfr.h' and/or `gmp.h' (used by `mpfr.h') are included
+several times (possibly from another header file), `<stdio.h>' and/or
+`<stdarg.h>' (or `<varargs.h>') should be included *before the first
+inclusion* of `mpfr.h' or `gmp.h'.  Alternatively, you can define
+`MPFR_USE_FILE' (for MPFR I/O functions) and/or `MPFR_USE_VA_LIST' (for
+MPFR functions with `va_list' parameters) anywhere before the last
+inclusion of `mpfr.h'.  As a consequence, if your file is a public
+header that includes `mpfr.h', you need to use the latter method.
+
+   When calling a MPFR macro, it is not allowed to have previously
+defined a macro with the same name as some keywords (currently `do',
+`while' and `sizeof').
+
+   You can avoid the use of MPFR macros encapsulating functions by
+defining the `MPFR_USE_NO_MACRO' macro before `mpfr.h' is included.  In
+general this should not be necessary, but this can be useful when
+debugging user code: with some macros, the compiler may emit spurious
+warnings with some warning options, and macros can prevent some
+prototype checking.
+
+   All programs using MPFR must link against both `libmpfr' and
+`libgmp' libraries.  On a typical Unix-like system this can be done
+with `-lmpfr -lgmp' (in that order), for example:
+
+     gcc myprogram.c -lmpfr -lgmp
+
+   MPFR is built using Libtool and an application can use that to link
+if desired, *note GNU Libtool: (libtool.info)Top.
+
+   If MPFR has been installed to a non-standard location, then it may be
+necessary to set up environment variables such as `C_INCLUDE_PATH' and
+`LIBRARY_PATH', or use `-I' and `-L' compiler options, in order to
+point to the right directories. For a shared library, it may also be
+necessary to set up some sort of run-time library path (e.g.,
+`LD_LIBRARY_PATH') on some systems. Please read the `INSTALL' file for
+additional information.

+
+4.2 Nomenclature and Types
+==========================
+
+A "floating-point number", or "float" for short, is an arbitrary
+precision significand (also called mantissa) with a limited precision
+exponent. The C data type for such objects is `mpfr_t' (internally
+defined as a one-element array of a structure, and `mpfr_ptr' is the C
+data type representing a pointer to this structure). A floating-point
+number can have three special values: Not-a-Number (NaN) or plus or
+minus Infinity. NaN represents an uninitialized object, the result of
+an invalid operation (like 0 divided by 0), or a value that cannot be
+determined (like +Infinity minus +Infinity). Moreover, like in the IEEE
+754 standard, zero is signed, i.e., there are both +0 and -0; the
+behavior is the same as in the IEEE 754 standard and it is generalized
+to the other functions supported by MPFR. Unless documented otherwise,
+the sign bit of a NaN is unspecified.
+
+The "precision" is the number of bits used to represent the significand
+of a floating-point number; the corresponding C data type is
+`mpfr_prec_t'.  The precision can be any integer between
+`MPFR_PREC_MIN' and `MPFR_PREC_MAX'. In the current implementation,
+`MPFR_PREC_MIN' is equal to 2.
+
+   Warning! MPFR needs to increase the precision internally, in order to
+provide accurate results (and in particular, correct rounding). Do not
+attempt to set the precision to any value near `MPFR_PREC_MAX',
+otherwise MPFR will abort due to an assertion failure. Moreover, you
+may reach some memory limit on your platform, in which case the program
+may abort, crash or have undefined behavior (depending on your C
+implementation).
+
+The "rounding mode" specifies the way to round the result of a
+floating-point operation, in case the exact result can not be
+represented exactly in the destination significand; the corresponding C
+data type is `mpfr_rnd_t'.
+
+
+File: mpfr.info,  Node: MPFR Variable Conventions,  Next: Rounding Modes,  Prev: Nomenclature and Types,  Up: MPFR Basics
+
+4.3 MPFR Variable Conventions
+=============================
+
+Before you can assign to an MPFR variable, you need to initialize it by
+calling one of the special initialization functions.  When you're done
+with a variable, you need to clear it out, using one of the functions
+for that purpose.  A variable should only be initialized once, or at
+least cleared out between each initialization.  After a variable has
+been initialized, it may be assigned to any number of times.  For
+efficiency reasons, avoid to initialize and clear out a variable in
+loops.  Instead, initialize it before entering the loop, and clear it
+out after the loop has exited.  You do not need to be concerned about
+allocating additional space for MPFR variables, since any variable has
+a significand of fixed size.  Hence unless you change its precision, or
+clear and reinitialize it, a floating-point variable will have the same
+allocated space during all its life.
+
+   As a general rule, all MPFR functions expect output arguments before
+input arguments.  This notation is based on an analogy with the
+assignment operator.  MPFR allows you to use the same variable for both
+input and output in the same expression.  For example, the main
+function for floating-point multiplication, `mpfr_mul', can be used
+like this: `mpfr_mul (x, x, x, rnd)'.  This computes the square of X
+with rounding mode `rnd' and puts the result back in X.
+
+
+File: mpfr.info,  Node: Rounding Modes,  Next: Floating-Point Values on Special Numbers,  Prev: MPFR Variable Conventions,  Up: MPFR Basics
+
+4.4 Rounding Modes
+==================
+
+The following five rounding modes are supported:
+
+   * `MPFR_RNDN': round to nearest (roundTiesToEven in IEEE 754-2008),
+
+   * `MPFR_RNDZ': round toward zero (roundTowardZero in IEEE 754-2008),
+
+   * `MPFR_RNDU': round toward plus infinity (roundTowardPositive in
+     IEEE 754-2008),
+
+   * `MPFR_RNDD': round toward minus infinity (roundTowardNegative in
+     IEEE 754-2008),
+
+   * `MPFR_RNDA': round away from zero.
+
+   The `round to nearest' mode works as in the IEEE 754 standard: in
+case the number to be rounded lies exactly in the middle of two
+representable numbers, it is rounded to the one with the least
+significant bit set to zero.  For example, the number 2.5, which is
+represented by (10.1) in binary, is rounded to (10.0)=2 with a
+precision of two bits, and not to (11.0)=3.  This rule avoids the
+"drift" phenomenon mentioned by Knuth in volume 2 of The Art of
+Computer Programming (Section 4.2.2).
+
+   Most MPFR functions take as first argument the destination variable,
+as second and following arguments the input variables, as last argument
+a rounding mode, and have a return value of type `int', called the
+"ternary value". The value stored in the destination variable is
+correctly rounded, i.e., MPFR behaves as if it computed the result with
+an infinite precision, then rounded it to the precision of this
+variable.  The input variables are regarded as exact (in particular,
+their precision does not affect the result).
+
+   As a consequence, in case of a non-zero real rounded result, the
+error on the result is less or equal to 1/2 ulp (unit in the last
+place) of that result in the rounding to nearest mode, and less than 1
+ulp of that result in the directed rounding modes (a ulp is the weight
+of the least significant represented bit of the result after rounding).
+
+   Unless documented otherwise, functions returning an `int' return a
+ternary value.  If the ternary value is zero, it means that the value
+stored in the destination variable is the exact result of the
+corresponding mathematical function. If the ternary value is positive
+(resp. negative), it means the value stored in the destination variable
+is greater (resp. lower) than the exact result. For example with the
+`MPFR_RNDU' rounding mode, the ternary value is usually positive,
+except when the result is exact, in which case it is zero. In the case
+of an infinite result, it is considered as inexact when it was obtained
+by overflow, and exact otherwise. A NaN result (Not-a-Number) always
+corresponds to an exact return value.  The opposite of a returned
+ternary value is guaranteed to be representable in an `int'.
+
+   Unless documented otherwise, functions returning as result the value
+`1' (or any other value specified in this manual) for special cases
+(like `acos(0)') yield an overflow or an underflow if that value is not
+representable in the current exponent range.
+

+
+4.5 Floating-Point Values on Special Numbers
+============================================
+
+This section specifies the floating-point values (of type `mpfr_t')
+returned by MPFR functions (where by "returned" we mean here the
+modified value of the destination object, which should not be mixed
+with the ternary return value of type `int' of those functions).  For
+functions returning several values (like `mpfr_sin_cos'), the rules
+apply to each result separately.
+
+   Functions can have one or several input arguments. An input point is
+a mapping from these input arguments to the set of the MPFR numbers.
+When none of its components are NaN, an input point can also be seen as
+a tuple in the extended real numbers (the set of the real numbers with
+both infinities).
+
+   When the input point is in the domain of the mathematical function,
+the result is rounded as described in Section "Rounding Modes" (but see
+below for the specification of the sign of an exact zero). Otherwise
+the general rules from this section apply unless stated otherwise in
+the description of the MPFR function (*note MPFR Interface::).
+
+   When the input point is not in the domain of the mathematical
+function but is in its closure in the extended real numbers and the
+function can be extended by continuity, the result is the obtained
+limit.  Examples: `mpfr_hypot' on (+Inf,0) gives +Inf. But `mpfr_pow'
+cannot be defined on (1,+Inf) using this rule, as one can find
+sequences (X_N,Y_N) such that X_N goes to 1, Y_N goes to +Inf and X_N
+to the Y_N goes to any positive value when N goes to the infinity.
+
+   When the input point is in the closure of the domain of the
+mathematical function and an input argument is +0 (resp. -0), one
+considers the limit when the corresponding argument approaches 0 from
+above (resp. below). If the limit is not defined (e.g., `mpfr_log' on
+-0), the behavior is specified in the description of the MPFR function.
+
+   When the result is equal to 0, its sign is determined by considering
+the limit as if the input point were not in the domain: If one
+approaches 0 from above (resp. below), the result is +0 (resp. -0); for
+example, `mpfr_sin' on +0 gives +0.  In the other cases, the sign is
+specified in the description of the MPFR function; for example
+`mpfr_max' on -0 and +0 gives +0.
+
+   When the input point is not in the closure of the domain of the
+function, the result is NaN. Example: `mpfr_sqrt' on -17 gives NaN.
+
+   When an input argument is NaN, the result is NaN, possibly except
+when a partial function is constant on the finite floating-point
+numbers; such a case is always explicitly specified in *note MPFR
+Interface::.  Example: `mpfr_hypot' on (NaN,0) gives NaN, but
+`mpfr_hypot' on (NaN,+Inf) gives +Inf (as specified in *note Special
+Functions::), since for any finite input X, `mpfr_hypot' on (X,+Inf)
+gives +Inf.

+
+4.6 Exceptions
+==============
+
+MPFR supports 6 exception types:
+
+   * Underflow: An underflow occurs when the exact result of a function
+     is a non-zero real number and the result obtained after the
+     rounding, assuming an unbounded exponent range (for the rounding),
+     has an exponent smaller than the minimum value of the current
+     exponent range. (In the round-to-nearest mode, the halfway case is
+     rounded toward zero.)
+
+     Note: This is not the single possible definition of the underflow.
+     MPFR chooses to consider the underflow _after_ rounding. The
+     underflow before rounding can also be defined. For instance,
+     consider a function that has the exact result 7 multiplied by two
+     to the power E-4, where E is the smallest exponent (for a
+     significand between 1/2 and 1), with a 2-bit target precision and
+     rounding toward plus infinity.  The exact result has the exponent
+     E-1. With the underflow before rounding, such a function call
+     would yield an underflow, as E-1 is outside the current exponent
+     range. However, MPFR first considers the rounded result assuming
+     an unbounded exponent range.  The exact result cannot be
+     represented exactly in precision 2, and here, it is rounded to 0.5
+     times 2 to E, which is representable in the current exponent
+     range. As a consequence, this will not yield an underflow in MPFR.
+
+   * Overflow: An overflow occurs when the exact result of a function
+     is a non-zero real number and the result obtained after the
+     rounding, assuming an unbounded exponent range (for the rounding),
+     has an exponent larger than the maximum value of the current
+     exponent range. In the round-to-nearest mode, the result is
+     infinite.  Note: unlike the underflow case, there is only one
+     possible definition of overflow here.
+
+   * Divide-by-zero: An exact infinite result is obtained from finite
+     inputs.
+
+   * NaN: A NaN exception occurs when the result of a function is NaN.
+
+   * Inexact: An inexact exception occurs when the result of a function
+     cannot be represented exactly and must be rounded.
+
+   * Range error: A range exception occurs when a function that does
+     not return a MPFR number (such as comparisons and conversions to
+     an integer) has an invalid result (e.g., an argument is NaN in
+     `mpfr_cmp', or a conversion to an integer cannot be represented in
+     the target type).
+
+
+   MPFR has a global flag for each exception, which can be cleared, set
+or tested by functions described in *note Exception Related Functions::.
+
+   Differences with the ISO C99 standard:
+
+   * In C, only quiet NaNs are specified, and a NaN propagation does not
+     raise an invalid exception. Unless explicitly stated otherwise,
+     MPFR sets the NaN flag whenever a NaN is generated, even when a
+     NaN is propagated (e.g., in NaN + NaN), as if all NaNs were
+     signaling.
+
+   * An invalid exception in C corresponds to either a NaN exception or
+     a range error in MPFR.

+
+4.7 Memory Handling
+===================
+
+MPFR functions may create caches, e.g., when computing constants such
+as Pi, either because the user has called a function like
+`mpfr_const_pi' directly or because such a function was called
+internally by the MPFR library itself to compute some other function.
+
+   At any time, the user can free the various caches with
+`mpfr_free_cache'. It is strongly advised to do that before terminating
+a thread, or before exiting when using tools like `valgrind' (to avoid
+memory leaks being reported).
+
+   MPFR internal data such as flags, the exponent range, the default
+precision and rounding mode, and caches (i.e., data that are not
+accessed via parameters) are either global (if MPFR has not been
+compiled as thread safe) or per-thread (thread local storage, TLS).
+The initial values of TLS data after a thread is created entirely
+depend on the compiler and thread implementation (MPFR simply does a
+conventional variable initialization, the variables being declared with
+an implementation-defined TLS specifier).
+
+

+
+5 MPFR Interface
+****************
+
+The floating-point functions expect arguments of type `mpfr_t'.
+
+   The MPFR floating-point functions have an interface that is similar
+to the GNU MP functions.  The function prefix for floating-point
+operations is `mpfr_'.
+
+   The user has to specify the precision of each variable.  A
+computation that assigns a variable will take place with the precision
+of the assigned variable; the cost of that computation should not
+depend on the precision of variables used as input (on average).
+
+   The semantics of a calculation in MPFR is specified as follows:
+Compute the requested operation exactly (with "infinite accuracy"), and
+round the result to the precision of the destination variable, with the
+given rounding mode.  The MPFR floating-point functions are intended to
+be a smooth extension of the IEEE 754 arithmetic. The results obtained
+on a given computer are identical to those obtained on a computer with
+a different word size, or with a different compiler or operating system.
+
+   MPFR _does not keep track_ of the accuracy of a computation. This is
+left to the user or to a higher layer (for example the MPFI library for
+interval arithmetic).  As a consequence, if two variables are used to
+store only a few significant bits, and their product is stored in a
+variable with large precision, then MPFR will still compute the result
+with full precision.
+
+   The value of the standard C macro `errno' may be set to non-zero by
+any MPFR function or macro, whether or not there is an error.

+
+5.1 Initialization Functions
+============================
+
+An `mpfr_t' object must be initialized before storing the first value in
+it.  The functions `mpfr_init' and `mpfr_init2' are used for that
+purpose.
+
+ -- Function: void mpfr_init2 (mpfr_t X, mpfr_prec_t PREC)
+     Initialize X, set its precision to be *exactly* PREC bits and its
+     value to NaN. (Warning: the corresponding MPF function initializes
+     to zero instead.)
+
+     Normally, a variable should be initialized once only or at least
+     be cleared, using `mpfr_clear', between initializations.  To
+     change the precision of a variable which has already been
+     initialized, use `mpfr_set_prec'.  The precision PREC must be an
+     integer between `MPFR_PREC_MIN' and `MPFR_PREC_MAX' (otherwise the
+     behavior is undefined).
+
+ -- Function: void mpfr_inits2 (mpfr_prec_t PREC, mpfr_t X, ...)
+     Initialize all the `mpfr_t' variables of the given variable
+     argument `va_list', set their precision to be *exactly* PREC bits
+     and their value to NaN.  See `mpfr_init2' for more details.  The
+     `va_list' is assumed to be composed only of type `mpfr_t' (or
+     equivalently `mpfr_ptr').  It begins from X, and ends when it
+     encounters a null pointer (whose type must also be `mpfr_ptr').
+
+ -- Function: void mpfr_clear (mpfr_t X)
+     Free the space occupied by the significand of X.  Make sure to
+     call this function for all `mpfr_t' variables when you are done
+     with them.
+
+ -- Function: void mpfr_clears (mpfr_t X, ...)
+     Free the space occupied by all the `mpfr_t' variables of the given
+     `va_list'. See `mpfr_clear' for more details.  The `va_list' is
+     assumed to be composed only of type `mpfr_t' (or equivalently
+     `mpfr_ptr').  It begins from X, and ends when it encounters a null
+     pointer (whose type must also be `mpfr_ptr').
+
+   Here is an example of how to use multiple initialization functions
+(since `NULL' is not necessarily defined in this context, we use
+`(mpfr_ptr) 0' instead, but `(mpfr_ptr) NULL' is also correct).
+
+     {
+       mpfr_t x, y, z, t;
+       mpfr_inits2 (256, x, y, z, t, (mpfr_ptr) 0);
+       ...
+       mpfr_clears (x, y, z, t, (mpfr_ptr) 0);
+     }
+
+ -- Function: void mpfr_init (mpfr_t X)
+     Initialize X, set its precision to the default precision, and set
+     its value to NaN.  The default precision can be changed by a call
+     to `mpfr_set_default_prec'.
+
+     Warning! In a given program, some other libraries might change the
+     default precision and not restore it. Thus it is safer to use
+     `mpfr_init2'.
+
+ -- Function: void mpfr_inits (mpfr_t X, ...)
+     Initialize all the `mpfr_t' variables of the given `va_list', set
+     their precision to the default precision and their value to NaN.
+     See `mpfr_init' for more details.  The `va_list' is assumed to be
+     composed only of type `mpfr_t' (or equivalently `mpfr_ptr').  It
+     begins from X, and ends when it encounters a null pointer (whose
+     type must also be `mpfr_ptr').
+
+     Warning! In a given program, some other libraries might change the
+     default precision and not restore it. Thus it is safer to use
+     `mpfr_inits2'.
+
+ -- Macro: MPFR_DECL_INIT (NAME, PREC)
+     This macro declares NAME as an automatic variable of type `mpfr_t',
+     initializes it and sets its precision to be *exactly* PREC bits
+     and its value to NaN. NAME must be a valid identifier.  You must
+     use this macro in the declaration section.  This macro is much
+     faster than using `mpfr_init2' but has some drawbacks:
+
+        * You *must not* call `mpfr_clear' with variables created with
+          this macro (the storage is allocated at the point of
+          declaration and deallocated when the brace-level is exited).
+
+        * You *cannot* change their precision.
+
+        * You *should not* create variables with huge precision with
+          this macro.
+
+        * Your compiler must support `Non-Constant Initializers'
+          (standard in C++ and ISO C99) and `Token Pasting' (standard
+          in ISO C89). If PREC is not a constant expression, your
+          compiler must support `variable-length automatic arrays'
+          (standard in ISO C99). GCC 2.95.3 and above supports all
+          these features.  If you compile your program with GCC in C89
+          mode and with `-pedantic', you may want to define the
+          `MPFR_USE_EXTENSION' macro to avoid warnings due to the
+          `MPFR_DECL_INIT' implementation.
+
+ -- Function: void mpfr_set_default_prec (mpfr_prec_t PREC)
+     Set the default precision to be *exactly* PREC bits, where PREC
+     can be any integer between `MPFR_PREC_MIN' and `MPFR_PREC_MAX'.
+     The precision of a variable means the number of bits used to store
+     its significand.  All subsequent calls to `mpfr_init' or
+     `mpfr_inits' will use this precision, but previously initialized
+     variables are unaffected.  The default precision is set to 53 bits
+     initially.
+
+     Note: when MPFR is built with the `--enable-thread-safe' configure
+     option, the default precision is local to each thread. *Note
+     Memory Handling::, for more information.
+
+ -- Function: mpfr_prec_t mpfr_get_default_prec (void)
+     Return the current default MPFR precision in bits.  See the
+     documentation of `mpfr_set_default_prec'.
+
+   Here is an example on how to initialize floating-point variables:
+
+     {
+       mpfr_t x, y;
+       mpfr_init (x);                /* use default precision */
+       mpfr_init2 (y, 256);          /* precision _exactly_ 256 bits */
+       ...
+       /* When the program is about to exit, do ... */
+       mpfr_clear (x);
+       mpfr_clear (y);
+       mpfr_free_cache ();           /* free the cache for constants like pi */
+     }
+
+   The following functions are useful for changing the precision during
+a calculation.  A typical use would be for adjusting the precision
+gradually in iterative algorithms like Newton-Raphson, making the
+computation precision closely match the actual accurate part of the
+numbers.
+
+ -- Function: void mpfr_set_prec (mpfr_t X, mpfr_prec_t PREC)
+     Reset the precision of X to be *exactly* PREC bits, and set its
+     value to NaN.  The previous value stored in X is lost. It is
+     equivalent to a call to `mpfr_clear(x)' followed by a call to
+     `mpfr_init2(x, prec)', but more efficient as no allocation is done
+     in case the current allocated space for the significand of X is
+     enough.  The precision PREC can be any integer between
+     `MPFR_PREC_MIN' and `MPFR_PREC_MAX'.  In case you want to keep the
+     previous value stored in X, use `mpfr_prec_round' instead.
+
+ -- Function: mpfr_prec_t mpfr_get_prec (mpfr_t X)
+     Return the precision of X, i.e., the number of bits used to store
+     its significand.

+5.2 Assignment Functions
+========================
+
+These functions assign new values to already initialized floats (*note
+Initialization Functions::).
+
+ -- Function: int mpfr_set (mpfr_t ROP, mpfr_t OP, mpfr_rnd_t RND)
+ -- Function: int mpfr_set_ui (mpfr_t ROP, unsigned long int OP,
+          mpfr_rnd_t RND)
+ -- Function: int mpfr_set_si (mpfr_t ROP, long int OP, mpfr_rnd_t RND)
+ -- Function: int mpfr_set_uj (mpfr_t ROP, uintmax_t OP, mpfr_rnd_t RND)
+ -- Function: int mpfr_set_sj (mpfr_t ROP, intmax_t OP, mpfr_rnd_t RND)
+ -- Function: int mpfr_set_flt (mpfr_t ROP, float OP, mpfr_rnd_t RND)
+ -- Function: int mpfr_set_d (mpfr_t ROP, double OP, mpfr_rnd_t RND)
+ -- Function: int mpfr_set_ld (mpfr_t ROP, long double OP, mpfr_rnd_t
+          RND)
+ -- Function: int mpfr_set_decimal64 (mpfr_t ROP, _Decimal64 OP,
+          mpfr_rnd_t RND)
+ -- Function: int mpfr_set_z (mpfr_t ROP, mpz_t OP, mpfr_rnd_t RND)
+ -- Function: int mpfr_set_q (mpfr_t ROP, mpq_t OP, mpfr_rnd_t RND)
+ -- Function: int mpfr_set_f (mpfr_t ROP, mpf_t OP, mpfr_rnd_t RND)
+     Set the value of ROP from OP, rounded toward the given direction
+     RND.  Note that the input 0 is converted to +0 by `mpfr_set_ui',
+     `mpfr_set_si', `mpfr_set_uj', `mpfr_set_sj', `mpfr_set_z',
+     `mpfr_set_q' and `mpfr_set_f', regardless of the rounding mode.
+     If the system does not support the IEEE 754 standard,
+     `mpfr_set_flt', `mpfr_set_d', `mpfr_set_ld' and
+     `mpfr_set_decimal64' might not preserve the signed zeros.  The
+     `mpfr_set_decimal64' function is built only with the configure
+     option `--enable-decimal-float', which also requires
+     `--with-gmp-build', and when the compiler or system provides the
+     `_Decimal64' data type (recent versions of GCC support this data
+     type); to use `mpfr_set_decimal64', one should define the macro
+     `MPFR_WANT_DECIMAL_FLOATS' before including `mpfr.h'.
+     `mpfr_set_q' might fail if the numerator (or the denominator) can
+     not be represented as a `mpfr_t'.
+
+     Note: If you want to store a floating-point constant to a `mpfr_t',
+     you should use `mpfr_set_str' (or one of the MPFR constant
+     functions, such as `mpfr_const_pi' for Pi) instead of
+     `mpfr_set_flt', `mpfr_set_d', `mpfr_set_ld' or
+     `mpfr_set_decimal64'.  Otherwise the floating-point constant will
+     be first converted into a reduced-precision (e.g., 53-bit) binary
+     (or decimal, for `mpfr_set_decimal64') number before MPFR can work
+     with it.
+
+ -- Function: int mpfr_set_ui_2exp (mpfr_t ROP, unsigned long int OP,
+          mpfr_exp_t E, mpfr_rnd_t RND)
+ -- Function: int mpfr_set_si_2exp (mpfr_t ROP, long int OP, mpfr_exp_t
+          E, mpfr_rnd_t RND)
+ -- Function: int mpfr_set_uj_2exp (mpfr_t ROP, uintmax_t OP, intmax_t
+          E, mpfr_rnd_t RND)
+ -- Function: int mpfr_set_sj_2exp (mpfr_t ROP, intmax_t OP, intmax_t
+          E, mpfr_rnd_t RND)
+ -- Function: int mpfr_set_z_2exp (mpfr_t ROP, mpz_t OP, mpfr_exp_t E,
+          mpfr_rnd_t RND)
+     Set the value of ROP from OP multiplied by two to the power E,
+     rounded toward the given direction RND.  Note that the input 0 is
+     converted to +0.
+
+ -- Function: int mpfr_set_str (mpfr_t ROP, const char *S, int BASE,
+          mpfr_rnd_t RND)
+     Set ROP to the value of the string S in base BASE, rounded in the
+     direction RND.  See the documentation of `mpfr_strtofr' for a
+     detailed description of the valid string formats.  Contrary to
+     `mpfr_strtofr', `mpfr_set_str' requires the _whole_ string to
+     represent a valid floating-point number.
+
+     The meaning of the return value differs from other MPFR functions:
+     it is 0 if the entire string up to the final null character is a
+     valid number in base BASE; otherwise it is -1, and ROP may have
+     changed (users interested in the *note ternary value:: should use
+     `mpfr_strtofr' instead).
+
+     Note: it is preferable to use `mpfr_set_str' if one wants to
+     distinguish between an infinite ROP value coming from an infinite
+     S or from an overflow.
+
+ -- Function: int mpfr_strtofr (mpfr_t ROP, const char *NPTR, char
+          **ENDPTR, int BASE, mpfr_rnd_t RND)
+     Read a floating-point number from a string NPTR in base BASE,
+     rounded in the direction RND; BASE must be either 0 (to detect the
+     base, as described below) or a number from 2 to 62 (otherwise the
+     behavior is undefined). If NPTR starts with valid data, the result
+     is stored in ROP and `*ENDPTR' points to the character just after
+     the valid data (if ENDPTR is not a null pointer); otherwise ROP is
+     set to zero (for consistency with `strtod') and the value of NPTR
+     is stored in the location referenced by ENDPTR (if ENDPTR is not a
+     null pointer). The usual ternary value is returned.
+
+     Parsing follows the standard C `strtod' function with some
+     extensions.  After optional leading whitespace, one has a subject
+     sequence consisting of an optional sign (`+' or `-'), and either
+     numeric data or special data. The subject sequence is defined as
+     the longest initial subsequence of the input string, starting with
+     the first non-whitespace character, that is of the expected form.
+
+     The form of numeric data is a non-empty sequence of significand
+     digits with an optional decimal point, and an optional exponent
+     consisting of an exponent prefix followed by an optional sign and
+     a non-empty sequence of decimal digits. A significand digit is
+     either a decimal digit or a Latin letter (62 possible characters),
+     with `A' = 10, `B' = 11, ..., `Z' = 35; case is ignored in bases
+     less or equal to 36, in bases larger than 36, `a' = 36, `b' = 37,
+     ..., `z' = 61.  The value of a significand digit must be strictly
+     less than the base.  The decimal point can be either the one
+     defined by the current locale or the period (the first one is
+     accepted for consistency with the C standard and the practice, the
+     second one is accepted to allow the programmer to provide MPFR
+     numbers from strings in a way that does not depend on the current
+     locale).  The exponent prefix can be `e' or `E' for bases up to
+     10, or `@' in any base; it indicates a multiplication by a power
+     of the base. In bases 2 and 16, the exponent prefix can also be
+     `p' or `P', in which case the exponent, called _binary exponent_,
+     indicates a multiplication by a power of 2 instead of the base
+     (there is a difference only for base 16); in base 16 for example
+     `1p2' represents 4 whereas `1@2' represents 256. The value of an
+     exponent is always written in base 10.
+
+     If the argument BASE is 0, then the base is automatically detected
+     as follows. If the significand starts with `0b' or `0B', base 2 is
+     assumed. If the significand starts with `0x' or `0X', base 16 is
+     assumed. Otherwise base 10 is assumed.
+
+     Note: The exponent (if present) must contain at least a digit.
+     Otherwise the possible exponent prefix and sign are not part of
+     the number (which ends with the significand). Similarly, if `0b',
+     `0B', `0x' or `0X' is not followed by a binary/hexadecimal digit,
+     then the subject sequence stops at the character `0', thus 0 is
+     read.
+
+     Special data (for infinities and NaN) can be `@inf@' or
+     `@nan@(n-char-sequence-opt)', and if BASE <= 16, it can also be
+     `infinity', `inf', `nan' or `nan(n-char-sequence-opt)', all case
+     insensitive.  A `n-char-sequence-opt' is a possibly empty string
+     containing only digits, Latin letters and the underscore (0, 1, 2,
+     ..., 9, a, b, ..., z, A, B, ..., Z, _). Note: one has an optional
+     sign for all data, even NaN.  For example,
+     `-@nAn@(This_Is_Not_17)' is a valid representation for NaN in base
+     17.
+
+
+ -- Function: void mpfr_set_nan (mpfr_t X)
+ -- Function: void mpfr_set_inf (mpfr_t X, int SIGN)
+ -- Function: void mpfr_set_zero (mpfr_t X, int SIGN)
+     Set the variable X to NaN (Not-a-Number), infinity or zero
+     respectively.  In `mpfr_set_inf' or `mpfr_set_zero', X is set to
+     plus infinity or plus zero iff SIGN is nonnegative; in
+     `mpfr_set_nan', the sign bit of the result is unspecified.
+
+ -- Function: void mpfr_swap (mpfr_t X, mpfr_t Y)
+     Swap the values X and Y efficiently. Warning: the precisions are
+     exchanged too; in case the precisions are different, `mpfr_swap'
+     is thus not equivalent to three `mpfr_set' calls using a third
+     auxiliary variable.

+========================
+
+ -- Function: float mpfr_get_flt (mpfr_t OP, mpfr_rnd_t RND)
+ -- Function: double mpfr_get_d (mpfr_t OP, mpfr_rnd_t RND)
+ -- Function: long double mpfr_get_ld (mpfr_t OP, mpfr_rnd_t RND)
+ -- Function: _Decimal64 mpfr_get_decimal64 (mpfr_t OP, mpfr_rnd_t RND)
+     Convert OP to a `float' (respectively `double', `long double' or
+     `_Decimal64'), using the rounding mode RND.  If OP is NaN, some
+     fixed NaN (either quiet or signaling) or the result of 0.0/0.0 is
+     returned. If OP is ±Inf, an infinity of the same sign or the
+     result of ±1.0/0.0 is returned. If OP is zero, these functions
+     return a zero, trying to preserve its sign, if possible.  The
+     `mpfr_get_decimal64' function is built only under some conditions:
+     see the documentation of `mpfr_set_decimal64'.
+
+ -- Function: long mpfr_get_si (mpfr_t OP, mpfr_rnd_t RND)
+ -- Function: unsigned long mpfr_get_ui (mpfr_t OP, mpfr_rnd_t RND)
+ -- Function: intmax_t mpfr_get_sj (mpfr_t OP, mpfr_rnd_t RND)
+ -- Function: uintmax_t mpfr_get_uj (mpfr_t OP, mpfr_rnd_t RND)
+     Convert OP to a `long', an `unsigned long', an `intmax_t' or an
+     `uintmax_t' (respectively) after rounding it with respect to RND.
+     If OP is NaN, 0 is returned and the _erange_ flag is set.  If OP
+     is too big for the return type, the function returns the maximum
+     or the minimum of the corresponding C type, depending on the
+     direction of the overflow; the _erange_ flag is set too.  See also
+     `mpfr_fits_slong_p', `mpfr_fits_ulong_p', `mpfr_fits_intmax_p' and
+     `mpfr_fits_uintmax_p'.
+
+ -- Function: double mpfr_get_d_2exp (long *EXP, mpfr_t OP, mpfr_rnd_t
+          RND)
+ -- Function: long double mpfr_get_ld_2exp (long *EXP, mpfr_t OP,
+          mpfr_rnd_t RND)
+     Return D and set EXP (formally, the value pointed to by EXP) such
+     that 0.5<=abs(D)<1 and D times 2 raised to EXP equals OP rounded
+     to double (resp. long double) precision, using the given rounding
+     mode.  If OP is zero, then a zero of the same sign (or an unsigned
+     zero, if the implementation does not have signed zeros) is
+     returned, and EXP is set to 0.  If OP is NaN or an infinity, then
+     the corresponding double precision (resp. long-double precision)
+     value is returned, and EXP is undefined.
+
+ -- Function: int mpfr_frexp (mpfr_exp_t *EXP, mpfr_t Y, mpfr_t X,
+          mpfr_rnd_t RND)
+     Set EXP (formally, the value pointed to by EXP) and Y such that
+     0.5<=abs(Y)<1 and Y times 2 raised to EXP equals X rounded to the
+     precision of Y, using the given rounding mode.  If X is zero, then
+     Y is set to a zero of the same sign and EXP is set to 0.  If X is
+     NaN or an infinity, then Y is set to the same value and EXP is
+     undefined.
+
+ -- Function: mpfr_exp_t mpfr_get_z_2exp (mpz_t ROP, mpfr_t OP)
+     Put the scaled significand of OP (regarded as an integer, with the
+     precision of OP) into ROP, and return the exponent EXP (which may
+     be outside the current exponent range) such that OP exactly equals
+     ROP times 2 raised to the power EXP.  If OP is zero, the minimal
+     exponent `emin' is returned.  If OP is NaN or an infinity, the
+     _erange_ flag is set, ROP is set to 0, and the the minimal
+     exponent `emin' is returned.  The returned exponent may be less
+     than the minimal exponent `emin' of MPFR numbers in the current
+     exponent range; in case the exponent is not representable in the
+     `mpfr_exp_t' type, the _erange_ flag is set and the minimal value
+     of the `mpfr_exp_t' type is returned.
+
+ -- Function: int mpfr_get_z (mpz_t ROP, mpfr_t OP, mpfr_rnd_t RND)
+     Convert OP to a `mpz_t', after rounding it with respect to RND. If
+     OP is NaN or an infinity, the _erange_ flag is set, ROP is set to
+     0, and 0 is returned.
+
+ -- Function: int mpfr_get_f (mpf_t ROP, mpfr_t OP, mpfr_rnd_t RND)
+     Convert OP to a `mpf_t', after rounding it with respect to RND.
+     The _erange_ flag is set if OP is NaN or an infinity, which do not
+     exist in MPF.  If OP is NaN, then ROP is undefined.  If OP is an
+     +Inf (resp. -Inf), then ROP is set to the maximum (resp. minimum)
+     value in the precision of the MPF number; if a future MPF version
+     supports infinities, this behavior will be considered incorrect
+     and will change (portable programs should assume that ROP is set
+     either to this finite number or to an infinite number).  Note that
+     since MPFR currently has the same exponent type as MPF (but not
+     with the same radix), the range of values is much larger in MPF
+     than in MPFR, so that an overflow or underflow is not possible.
+
+ -- Function: char * mpfr_get_str (char *STR, mpfr_exp_t *EXPPTR, int
+          B, size_t N, mpfr_t OP, mpfr_rnd_t RND)
+     Convert OP to a string of digits in base B, with rounding in the
+     direction RND, where N is either zero (see below) or the number of
+     significant digits output in the string; in the latter case, N
+     must be greater or equal to 2. The base may vary from 2 to 62.  If
+     the input number is an ordinary number, the exponent is written
+     through the pointer EXPPTR (for input 0, the current minimal
+     exponent is written).
+
+     The generated string is a fraction, with an implicit radix point
+     immediately to the left of the first digit.  For example, the
+     number -3.1416 would be returned as "-31416" in the string and 1
+     written at EXPPTR.  If RND is to nearest, and OP is exactly in the
+     middle of two consecutive possible outputs, the one with an even
+     significand is chosen, where both significands are considered with
+     the exponent of OP.  Note that for an odd base, this may not
+     correspond to an even last digit: for example with 2 digits in
+     base 7, (14) and a half is rounded to (15) which is 12 in decimal,
+     (16) and a half is rounded to (20) which is 14 in decimal, and
+     (26) and a half is rounded to (26) which is 20 in decimal.
+
+     If N is zero, the number of digits of the significand is chosen
+     large enough so that re-reading the printed value with the same
+     precision, assuming both output and input use rounding to nearest,
+     will recover the original value of OP.  More precisely, in most
+     cases, the chosen precision of STR is the minimal precision m
+     depending only on P = PREC(OP) and B that satisfies the above
+     property, i.e., m = 1 + ceil(P*log(2)/log(B)), with P replaced by
+     P-1 if B is a power of 2, but in some very rare cases, it might be
+     m+1 (the smallest case for bases up to 62 is when P equals
+     186564318007 for bases 7 and 49).
+
+     If STR is a null pointer, space for the significand is allocated
+     using the current allocation function, and a pointer to the string
+     is returned.  To free the returned string, you must use
+     `mpfr_free_str'.
+
+     If STR is not a null pointer, it should point to a block of storage
+     large enough for the significand, i.e., at least `max(N + 2, 7)'.
+     The extra two bytes are for a possible minus sign, and for the
+     terminating null character, and the value 7 accounts for `-@Inf@'
+     plus the terminating null character.
+
+     A pointer to the string is returned, unless there is an error, in
+     which case a null pointer is returned.
+
+ -- Function: void mpfr_free_str (char *STR)
+     Free a string allocated by `mpfr_get_str' using the current
+     unallocation function.  The block is assumed to be `strlen(STR)+1'
+     bytes.  For more information about how it is done: *note Custom
+     Allocation: (gmp.info)Custom Allocation.

+     `unsigned short', `short', `uintmax_t', `intmax_t', when rounded
+     to an integer in the direction RND.

+          mpfr_rnd_t RND)

+ -- Function: int mpfr_cmp_f (mpfr_t OP1, mpf_t OP2)
+     Compare OP1 and OP2.  Return a positive value if OP1 > OP2, zero
+     if OP1 = OP2, and a negative value if OP1 < OP2.  Both OP1 and OP2
+     are considered to their full own precision, which may differ.  If

+     Note: These functions may be useful to distinguish the three

+     recommended to use the predicate functions (e.g., `mpfr_equal_p'

+
+ -- Function: int mpfr_cmpabs (mpfr_t OP1, mpfr_t OP2)

+
+ -- Macro: int mpfr_sgn (mpfr_t OP)
+     Return a positive value if OP > 0, zero if OP = 0, and a negative

+ -- Function: int mpfr_lessgreater_p (mpfr_t OP1, mpfr_t OP2)
+     Return non-zero if OP1 < OP2 or OP1 > OP2 (i.e., neither OP1, nor

+5.7 Special Functions
+=====================
+
+All those functions, except explicitly stated (for example
+`mpfr_sin_cos'), return a *note ternary value::, i.e., zero for an
+exact return value, a positive value for a return value larger than the
+exact result, and a negative value otherwise.
+
+   Important note: in some domains, computing special functions (either
+with correct or incorrect rounding) is expensive, even for small
+precision, for example the trigonometric and Bessel functions for large
+argument.
+
+ -- Function: int mpfr_log (mpfr_t ROP, mpfr_t OP, mpfr_rnd_t RND)
+ -- Function: int mpfr_log2 (mpfr_t ROP, mpfr_t OP, mpfr_rnd_t RND)
+ -- Function: int mpfr_log10 (mpfr_t ROP, mpfr_t OP, mpfr_rnd_t RND)
+     Set ROP to the natural logarithm of OP, log2(OP) or log10(OP),
+     respectively, rounded in the direction RND.  Set ROP to -Inf if OP
+     is -0 (i.e., the sign of the zero has no influence on the result).
+
+ -- Function: int mpfr_exp (mpfr_t ROP, mpfr_t OP, mpfr_rnd_t RND)
+ -- Function: int mpfr_exp2 (mpfr_t ROP, mpfr_t OP, mpfr_rnd_t RND)
+ -- Function: int mpfr_exp10 (mpfr_t ROP, mpfr_t OP, mpfr_rnd_t RND)
+     Set ROP to the exponential of OP,  to 2 power of OP or to 10 power
+     of OP, respectively, rounded in the direction RND.
+
+ -- Function: int mpfr_cos (mpfr_t ROP, mpfr_t OP, mpfr_rnd_t RND)
+ -- Function: int mpfr_sin (mpfr_t ROP, mpfr_t OP, mpfr_rnd_t RND)
+ -- Function: int mpfr_tan (mpfr_t ROP, mpfr_t OP, mpfr_rnd_t RND)
+     Set ROP to the cosine of OP, sine of OP, tangent of OP, rounded in
+     the direction RND.
+
+ -- Function: int mpfr_sin_cos (mpfr_t SOP, mpfr_t COP, mpfr_t OP,
+          mpfr_rnd_t RND)
+     Set simultaneously SOP to the sine of OP and COP to the cosine of
+     OP, rounded in the direction RND with the corresponding precisions
+     of SOP and COP, which must be different variables.  Return 0 iff
+     both results are exact, more precisely it returns s+4c where s=0
+     if SOP is exact, s=1 if SOP is larger than the sine of OP, s=2 if
+     SOP is smaller than the sine of OP, and similarly for c and the
+     cosine of OP.
+
+ -- Function: int mpfr_sec (mpfr_t ROP, mpfr_t OP, mpfr_rnd_t RND)
+ -- Function: int mpfr_csc (mpfr_t ROP, mpfr_t OP, mpfr_rnd_t RND)
+ -- Function: int mpfr_cot (mpfr_t ROP, mpfr_t OP, mpfr_rnd_t RND)
+     Set ROP to the secant of OP, cosecant of OP, cotangent of OP,
+     rounded in the direction RND.
+
+ -- Function: int mpfr_acos (mpfr_t ROP, mpfr_t OP, mpfr_rnd_t RND)
+ -- Function: int mpfr_asin (mpfr_t ROP, mpfr_t OP, mpfr_rnd_t RND)
+ -- Function: int mpfr_atan (mpfr_t ROP, mpfr_t OP, mpfr_rnd_t RND)
+     Set ROP to the arc-cosine, arc-sine or arc-tangent of OP, rounded
+     in the direction RND.  Note that since `acos(-1)' returns the
+     floating-point number closest to Pi according to the given
+     rounding mode, this number might not be in the output range 0 <=
+     ROP < \pi of the arc-cosine function; still, the result lies in
+     the image of the output range by the rounding function.  The same
+     holds for `asin(-1)', `asin(1)', `atan(-Inf)', `atan(+Inf)' or for
+     `atan(op)' with large OP and small precision of ROP.
+
+ -- Function: int mpfr_atan2 (mpfr_t ROP, mpfr_t Y, mpfr_t X,
+          mpfr_rnd_t RND)
+     Set ROP to the arc-tangent2 of Y and X, rounded in the direction
+     RND: if `x > 0', `atan2(y, x) = atan (y/x)'; if `x < 0', `atan2(y,
+     x) = sign(y)*(Pi - atan (abs(y/x)))', thus a number from -Pi to Pi.
+     As for `atan', in case the exact mathematical result is +Pi or -Pi,
+     its rounded result might be outside the function output range.
+
+     `atan2(y, 0)' does not raise any floating-point exception.
+     Special values are handled as described in the ISO C99 and IEEE
+     754-2008 standards for the `atan2' function:
+        * `atan2(+0, -0)' returns +Pi.
+
+        * `atan2(-0, -0)' returns -Pi.
+
+        * `atan2(+0, +0)' returns +0.
+
+        * `atan2(-0, +0)' returns -0.
+
+        * `atan2(+0, x)' returns +Pi for x < 0.
+
+        * `atan2(-0, x)' returns -Pi for x < 0.
+
+        * `atan2(+0, x)' returns +0 for x > 0.
+
+        * `atan2(-0, x)' returns -0 for x > 0.
+
+        * `atan2(y, 0)' returns -Pi/2 for y < 0.
+
+        * `atan2(y, 0)' returns +Pi/2 for y > 0.
+
+        * `atan2(+Inf, -Inf)' returns +3*Pi/4.
+
+        * `atan2(-Inf, -Inf)' returns -3*Pi/4.
+
+        * `atan2(+Inf, +Inf)' returns +Pi/4.
+
+        * `atan2(-Inf, +Inf)' returns -Pi/4.
+
+        * `atan2(+Inf, x)' returns +Pi/2 for finite x.
+
+        * `atan2(-Inf, x)' returns -Pi/2 for finite x.
+
+        * `atan2(y, -Inf)' returns +Pi for finite y > 0.
+
+        * `atan2(y, -Inf)' returns -Pi for finite y < 0.
+
+        * `atan2(y, +Inf)' returns +0 for finite y > 0.
+
+        * `atan2(y, +Inf)' returns -0 for finite y < 0.

+     hyperbolic cosine of OP, rounded in the direction RND with the
+     corresponding precision of SOP and COP, which must be different

+ -- Function: int mpfr_eint (mpfr_t ROP, mpfr_t OP, mpfr_rnd_t RND)
+     Set ROP to the exponential integral of OP, rounded in the

+     sum of Euler's constant, of the logarithm of OP, and of the sum
+     for k from 1 to infinity of OP to the power k, divided by k and
+     factorial(k).  For negative OP, ROP is set to NaN (this definition
+     for negative argument follows formula 5.1.2 from the Handbook of
+     Mathematical Functions from Abramowitz and Stegun, a future
+     version might use another definition).
+

+     Set ROP to real part of the dilogarithm of OP, rounded in the

+     Special values are handled as described in Section F.9.4.3 of the

+     Set ROP to the value of the Airy function Ai  on X, rounded in the

+     +Inf or -Inf, ROP is +0.  The current implementation is not
+     intended to be used with large arguments.  It works with abs(X)
+     typically smaller than 500. For larger arguments, other methods

+     constant 0.577..., of Catalan's constant 0.915..., respectively,
+     rounded in the direction RND. These functions cache the computed
+     values to avoid other calculations if a lower or equal precision
+     is requested. To free these caches, use `mpfr_free_cache'.
+
+ -- Function: void mpfr_free_cache (void)
+     Free various caches used by MPFR internally, in particular the
+     caches used by the functions computing constants
+     (`mpfr_const_log2', `mpfr_const_pi', `mpfr_const_euler' and
+     `mpfr_const_catalan').  You should call this function before
+     terminating a thread, even if you did not call these functions
+     directly (they could have been called internally).
+
+ -- Function: int mpfr_sum (mpfr_t ROP, mpfr_ptr const TAB[], unsigned
+          long int N, mpfr_rnd_t RND)
+     Set ROP to the sum of all elements of TAB, whose size is N,
+     rounded in the direction RND. Warning: for efficiency reasons, TAB
+     is an array of pointers to `mpfr_t', not an array of `mpfr_t'.  If
+     the returned `int' value is zero, ROP is guaranteed to be the
+     exact sum; otherwise ROP might be smaller than, equal to, or
+     larger than the exact sum (in accordance to the rounding mode).
+     However, `mpfr_sum' does guarantee the result is correctly rounded.

+
+5.8 Input and Output Functions
+==============================
+
+This section describes functions that perform input from an input/output
+stream, and functions that output to an input/output stream.  Passing a
+null pointer for a `stream' to any of these functions will make them
+read from `stdin' and write to `stdout', respectively.
+
+   When using any of these functions, you must include the `<stdio.h>'
+standard header before `mpfr.h', to allow `mpfr.h' to define prototypes
+for these functions.
+
+ -- Function: size_t mpfr_out_str (FILE *STREAM, int BASE, size_t N,
+          mpfr_t OP, mpfr_rnd_t RND)
+     Output OP on stream STREAM, as a string of digits in base BASE,
+     rounded in the direction RND.  The base may vary from 2 to 62.
+     Print N significant digits exactly, or if N is 0, enough digits so
+     that OP can be read back exactly (see `mpfr_get_str').
+
+     In addition to the significant digits, a decimal point (defined by
+     the current locale) at the right of the first digit and a trailing
+     exponent in base 10, in the form `eNNN', are printed. If BASE is
+     greater than 10, `@' will be used instead of `e' as exponent
+     delimiter.
+
+     Return the number of characters written, or if an error occurred,
+     return 0.
+
+ -- Function: size_t mpfr_inp_str (mpfr_t ROP, FILE *STREAM, int BASE,
+          mpfr_rnd_t RND)
+     Input a string in base BASE from stream STREAM, rounded in the
+     direction RND, and put the read float in ROP.
+
+     This function reads a word (defined as a sequence of characters
+     between whitespace) and parses it using `mpfr_set_str'.  See the
+     documentation of `mpfr_strtofr' for a detailed description of the
+     valid string formats.
+
+     Return the number of bytes read, or if an error occurred, return 0.

+5.9 Formatted Output Functions
+==============================
+
+5.9.1 Requirements
+------------------
+
+The class of `mpfr_printf' functions provides formatted output in a
+similar manner as the standard C `printf'. These functions are defined
+only if your system supports ISO C variadic functions and the
+corresponding argument access macros.
+
+   When using any of these functions, you must include the `<stdio.h>'
+standard header before `mpfr.h', to allow `mpfr.h' to define prototypes
+for these functions.
+
+5.9.2 Format String
+-------------------

+The format specification accepted by `mpfr_printf' is an extension of
+the `printf' one. The conversion specification is of the form:
+     % [flags] [width] [.[precision]] [type] [rounding] conv
+   `flags', `width', and `precision' have the same meaning as for the
+standard `printf' (in particular, notice that the `precision' is
+related to the number of digits displayed in the base chosen by `conv'
+and not related to the internal precision of the `mpfr_t' variable).
+`mpfr_printf' accepts the same `type' specifiers as GMP (except the
+non-standard and deprecated `q', use `ll' instead), namely the length
+modifiers defined in the C standard:
+
+     `h'       `short'
+     `hh'      `char'
+     `j'       `intmax_t' or `uintmax_t'
+     `l'       `long' or `wchar_t'
+     `ll'      `long long'
+     `L'       `long double'
+     `t'       `ptrdiff_t'
+     `z'       `size_t'
+
+   and the `type' specifiers defined in GMP plus `R' and `P' specific
+to MPFR (the second column in the table below shows the type of the
+argument read in the argument list and the kind of `conv' specifier to
+use after the `type' specifier):
+
+     `F'       `mpf_t', float conversions
+     `Q'       `mpq_t', integer conversions
+     `M'       `mp_limb_t', integer conversions
+     `N'       `mp_limb_t' array, integer conversions
+     `Z'       `mpz_t', integer conversions
+     `P'       `mpfr_prec_t', integer conversions
+     `R'       `mpfr_t', float conversions
+
+   The `type' specifiers have the same restrictions as those mentioned
+in the GMP documentation: *note Formatted Output Strings:
+(gmp.info)Formatted Output Strings.  In particular, the `type'
+specifiers (except `R' and `P') are supported only if they are
+supported by `gmp_printf' in your GMP build; this implies that the
+standard specifiers, such as `t', must _also_ be supported by your C
+library if you want to use them.
+
+   The `rounding' field is specific to `mpfr_t' arguments and should
+not be used with other types.
+
+   With conversion specification not involving `P' and `R' types,
+`mpfr_printf' behaves exactly as `gmp_printf'.
+
+   The `P' type specifies that a following `o', `u', `x', or `X'
+conversion specifier applies to a `mpfr_prec_t' argument.  It is needed
+because the `mpfr_prec_t' type does not necessarily correspond to an
+`unsigned int' or any fixed standard type.  The `precision' field
+specifies the minimum number of digits to appear. The default
+`precision' is 1.  For example:
+     mpfr_t x;
+     mpfr_prec_t p;
+     mpfr_init (x);
+     ...
+     p = mpfr_get_prec (x);
+     mpfr_printf ("variable x with %Pu bits", p);
+
+   The `R' type specifies that a following `a', `A', `b', `e', `E',
+`f', `F', `g', `G', or `n' conversion specifier applies to a `mpfr_t'
+argument.  The `R' type can be followed by a `rounding' specifier
+denoted by one of the following characters:
+
+     `U'       round toward plus infinity
+     `D'       round toward minus infinity
+     `Y'       round away from zero
+     `Z'       round toward zero
+     `N'       round to nearest (with ties to even)
+     `*'       rounding mode indicated by the
+               `mpfr_rnd_t' argument just before the
+               corresponding `mpfr_t' variable.
+
+   The default rounding mode is rounding to nearest.  The following
+three examples are equivalent:
+     mpfr_t x;
+     mpfr_init (x);
+     ...
+     mpfr_printf ("%.128Rf", x);
+     mpfr_printf ("%.128RNf", x);
+     mpfr_printf ("%.128R*f", MPFR_RNDN, x);
+
+   Note that the rounding away from zero mode is specified with `Y'
+because ISO C reserves the `A' specifier for hexadecimal output (see
+below).
+
+   The output `conv' specifiers allowed with `mpfr_t' parameter are:
+
+     `a' `A'   hex float, C99 style
+     `b'       binary output
+     `e' `E'   scientific format float
+     `f' `F'   fixed point float
+     `g' `G'   fixed or scientific float
+
+   The conversion specifier `b' which displays the argument in binary is
+specific to `mpfr_t' arguments and should not be used with other types.
+Other conversion specifiers have the same meaning as for a `double'
+argument.
+
+   In case of non-decimal output, only the significand is written in the
+specified base, the exponent is always displayed in decimal.  Special
+values are always displayed as `nan', `-inf', and `inf' for `a', `b',
+`e', `f', and `g' specifiers and `NAN', `-INF', and `INF' for `A', `E',
+`F', and `G' specifiers.
+
+   If the `precision' field is not empty, the `mpfr_t' number is
+rounded to the given precision in the direction specified by the
+rounding mode.  If the precision is zero with rounding to nearest mode
+and one of the following `conv' specifiers: `a', `A', `b', `e', `E',
+tie case is rounded to even when it lies between two consecutive values
+at the wanted precision which have the same exponent, otherwise, it is
+rounded away from zero.  For instance, 85 is displayed as "8e+1" and 95
+is displayed as "1e+2" with the format specification `"%.0RNe"'.  This
+also applies when the `g' (resp. `G') conversion specifier uses the `e'
+(resp. `E') style.  If the precision is set to a value greater than the
+maximum value for an `int', it will be silently reduced down to
+`INT_MAX'.
+
+   If the `precision' field is empty (as in `%Re' or `%.RE') with
+`conv' specifier `e' and `E', the number is displayed with enough
+digits so that it can be read back exactly, assuming that the input and
+output variables have the same precision and that the input and output
+rounding modes are both rounding to nearest (as for `mpfr_get_str').
+The default precision for an empty `precision' field with `conv'
+specifiers `f', `F', `g', and `G' is 6.

+5.9.3 Functions
+---------------
+
+For all the following functions, if the number of characters which
+ought to be written appears to exceed the maximum limit for an `int',
+nothing is written in the stream (resp. to `stdout', to BUF, to STR),
+the function returns -1, sets the _erange_ flag, and (in POSIX system
+only) `errno' is set to `EOVERFLOW'.
+
+ -- Function: int mpfr_fprintf (FILE *STREAM, const char *TEMPLATE, ...)
+ -- Function: int mpfr_vfprintf (FILE *STREAM, const char *TEMPLATE,
+          va_list AP)
+     Print to the stream STREAM the optional arguments under the
+     control of the template string TEMPLATE.  Return the number of
+     characters written or a negative value if an error occurred.
+
+ -- Function: int mpfr_printf (const char *TEMPLATE, ...)
+ -- Function: int mpfr_vprintf (const char *TEMPLATE, va_list AP)
+     Print to `stdout' the optional arguments under the control of the

+
+ -- Function: int mpfr_sprintf (char *BUF, const char *TEMPLATE, ...)
+ -- Function: int mpfr_vsprintf (char *BUF, const char *TEMPLATE,
+          va_list AP)
+     Form a null-terminated string corresponding to the optional
+     arguments under the control of the template string TEMPLATE, and
+     print it in BUF. No overlap is permitted between BUF and the other
+     arguments.  Return the number of characters written in the array
+     BUF _not counting_ the terminating null character or a negative
+     value if an error occurred.
+
+ -- Function: int mpfr_snprintf (char *BUF, size_t N, const char
+          *TEMPLATE, ...)
+ -- Function: int mpfr_vsnprintf (char *BUF, size_t N, const char
+          *TEMPLATE, va_list AP)
+     Form a null-terminated string corresponding to the optional
+     arguments under the control of the template string TEMPLATE, and
+     print it in BUF. If N is zero, nothing is written and BUF may be a
+     null pointer, otherwise, the N-1 first characters are written in
+     BUF and the N-th is a null character.  Return the number of
+     characters that would have been written had N be sufficiently
+     large, _not counting_ the terminating null character, or a
+     negative value if an error occurred.
+
+ -- Function: int mpfr_asprintf (char **STR, const char *TEMPLATE, ...)
+ -- Function: int mpfr_vasprintf (char **STR, const char *TEMPLATE,
+          va_list AP)
+     Write their output as a null terminated string in a block of
+     memory allocated using the current allocation function. A pointer
+     to the block is stored in STR. The block of memory must be freed
+     using `mpfr_free_str'.  The return value is the number of
+     characters written in the string, excluding the null-terminator,
+     or a negative value if an error occurred.

+5.10 Integer and Remainder Related Functions
+============================================
+
+ -- Function: int mpfr_rint (mpfr_t ROP, mpfr_t OP, mpfr_rnd_t RND)
+ -- Function: int mpfr_ceil (mpfr_t ROP, mpfr_t OP)
+ -- Function: int mpfr_floor (mpfr_t ROP, mpfr_t OP)
+ -- Function: int mpfr_round (mpfr_t ROP, mpfr_t OP)
+ -- Function: int mpfr_trunc (mpfr_t ROP, mpfr_t OP)
+     Set ROP to OP rounded to an integer.  `mpfr_rint' rounds to the
+     nearest representable integer in the given direction RND,
+     `mpfr_ceil' rounds to the next higher or equal representable
+     integer, `mpfr_floor' to the next lower or equal representable
+     integer, `mpfr_round' to the nearest representable integer,
+     rounding halfway cases away from zero (as in the roundTiesToAway
+     mode of IEEE 754-2008), and `mpfr_trunc' to the next representable
+     integer toward zero.
+
+     The returned value is zero when the result is exact, positive when
+     it is greater than the original value of OP, and negative when it
+     is smaller.  More precisely, the returned value is 0 when OP is an
+     integer representable in ROP, 1 or -1 when OP is an integer that
+     is not representable in ROP, 2 or -2 when OP is not an integer.
+
+     Note that `mpfr_round' is different from `mpfr_rint' called with
+     the rounding to nearest mode (where halfway cases are rounded to
+     an even integer or significand). Note also that no double rounding
+     is performed; for instance, 10.5 (1010.1 in binary) is rounded by
+     `mpfr_rint' with rounding to nearest to 12 (1100 in binary) in
+     2-bit precision, because the two enclosing numbers representable
+     on two bits are 8 and 12, and the closest is 12.  (If one first
+     rounded to an integer, one would round 10.5 to 10 with even
+     rounding, and then 10 would be rounded to 8 again with even
+     rounding.)
+
+ -- Function: int mpfr_rint_ceil (mpfr_t ROP, mpfr_t OP, mpfr_rnd_t RND)
+ -- Function: int mpfr_rint_floor (mpfr_t ROP, mpfr_t OP, mpfr_rnd_t
+          RND)
+ -- Function: int mpfr_rint_round (mpfr_t ROP, mpfr_t OP, mpfr_rnd_t
+          RND)
+ -- Function: int mpfr_rint_trunc (mpfr_t ROP, mpfr_t OP, mpfr_rnd_t
+          RND)
+     Set ROP to OP rounded to an integer.  `mpfr_rint_ceil' rounds to
+     the next higher or equal integer, `mpfr_rint_floor' to the next
+     lower or equal integer, `mpfr_rint_round' to the nearest integer,
+     rounding halfway cases away from zero, and `mpfr_rint_trunc' to
+     the next integer toward zero.  If the result is not representable,
+     it is rounded in the direction RND.  The returned value is the
+     ternary value associated with the considered round-to-integer
+     function (regarded in the same way as any other mathematical
+     function).  Contrary to `mpfr_rint', those functions do perform a
+     double rounding: first OP is rounded to the nearest integer in the
+     direction given by the function name, then this nearest integer
+     (if not representable) is rounded in the given direction RND.  For
+     example, `mpfr_rint_round' with rounding to nearest and a precision
+     of two bits rounds 6.5 to 7 (halfway cases away from zero), then 7
+     is rounded to 8 by the round-even rule, despite the fact that 6 is
+     also representable on two bits, and is closer to 6.5 than 8.
+
+ -- Function: int mpfr_frac (mpfr_t ROP, mpfr_t OP, mpfr_rnd_t RND)
+     Set ROP to the fractional part of OP, having the same sign as OP,
+     rounded in the direction RND (unlike in `mpfr_rint', RND affects
+     only how the exact fractional part is rounded, not how the
+     fractional part is generated).
+
+ -- Function: int mpfr_modf (mpfr_t IOP, mpfr_t FOP, mpfr_t OP,
+          mpfr_rnd_t RND)
+     Set simultaneously IOP to the integral part of OP and FOP to the
+     fractional part of OP, rounded in the direction RND with the
+     corresponding precision of IOP and FOP (equivalent to
+     `mpfr_trunc(IOP, OP, RND)' and `mpfr_frac(FOP, OP, RND)'). The
+     variables IOP and FOP must be different. Return 0 iff both results
+     are exact (see `mpfr_sin_cos' for a more detailed description of
+     the return value).
+
+ -- Function: int mpfr_fmod (mpfr_t R, mpfr_t X, mpfr_t Y, mpfr_rnd_t
+          RND)
+ -- Function: int mpfr_remainder (mpfr_t R, mpfr_t X, mpfr_t Y,
+          mpfr_rnd_t RND)
+ -- Function: int mpfr_remquo (mpfr_t R, long* Q, mpfr_t X, mpfr_t Y,
+          mpfr_rnd_t RND)
+     Set R to the value of X - NY, rounded according to the direction
+     RND, where N is the integer quotient of X divided by Y, defined as
+     follows: N is rounded toward zero for `mpfr_fmod', and to the
+     nearest integer (ties rounded to even) for `mpfr_remainder' and
+     `mpfr_remquo'.
+
+     Special values are handled as described in Section F.9.7.1 of the
+     ISO C99 standard: If X is infinite or Y is zero, R is NaN.  If Y
+     is infinite and X is finite, R is X rounded to the precision of R.
+     If R is zero, it has the sign of X.  The return value is the
+     ternary value corresponding to R.
+
+     Additionally, `mpfr_remquo' stores the low significant bits from
+     the quotient N in *Q (more precisely the number of bits in a
+     `long' minus one), with the sign of X divided by Y (except if
+     those low bits are all zero, in which case zero is returned).
+     Note that X may be so large in magnitude relative to Y that an
+     exact representation of the quotient is not practical.  The
+     `mpfr_remainder' and `mpfr_remquo' functions are useful for
+     additive argument reduction.

+5.11 Rounding Related Functions
+===============================
+
+ -- Function: void mpfr_set_default_rounding_mode (mpfr_rnd_t RND)
+     Set the default rounding mode to RND.  The default rounding mode
+     is to nearest initially.
+
+ -- Function: mpfr_rnd_t mpfr_get_default_rounding_mode (void)
+     Get the default rounding mode.
+
+ -- Function: int mpfr_prec_round (mpfr_t X, mpfr_prec_t PREC,
+          mpfr_rnd_t RND)
+     Round X according to RND with precision PREC, which must be an
+     integer between `MPFR_PREC_MIN' and `MPFR_PREC_MAX' (otherwise the
+     behavior is undefined).  If PREC is greater or equal to the
+     precision of X, then new space is allocated for the significand,
+     and it is filled with zeros.  Otherwise, the significand is
+     rounded to precision PREC with the given direction. In both cases,
+     the precision of X is changed to PREC.
+
+     Here is an example of how to use `mpfr_prec_round' to implement
+     Newton's algorithm to compute the inverse of A, assuming X is
+     already an approximation to N bits:
+            mpfr_set_prec (t, 2 * n);
+            mpfr_set (t, a, MPFR_RNDN);         /* round a to 2n bits */
+            mpfr_mul (t, t, x, MPFR_RNDN);      /* t is correct to 2n bits */
+            mpfr_ui_sub (t, 1, t, MPFR_RNDN);   /* high n bits cancel with 1 */
+            mpfr_prec_round (t, n, MPFR_RNDN);  /* t is correct to n bits */
+            mpfr_mul (t, t, x, MPFR_RNDN);      /* t is correct to n bits */
+            mpfr_prec_round (x, 2 * n, MPFR_RNDN); /* exact */
+            mpfr_add (x, x, t, MPFR_RNDN);      /* x is correct to 2n bits */
+
+ -- Function: int mpfr_can_round (mpfr_t B, mpfr_exp_t ERR, mpfr_rnd_t
+          RND1, mpfr_rnd_t RND2, mpfr_prec_t PREC)
+     Assuming B is an approximation of an unknown number X in the
+     direction RND1 with error at most two to the power E(b)-ERR where
+     E(b) is the exponent of B, return a non-zero value if one is able
+     to round correctly X to precision PREC with the direction RND2,
+     and 0 otherwise (including for NaN and Inf).  This function *does
+     not modify* its arguments.
+
+     If RND1 is `MPFR_RNDN', then the sign of the error is unknown, but
+     its absolute value is the same, so that the possible range is
+     twice as large as with a directed rounding for RND1.
+
+     Note: if one wants to also determine the correct *note ternary
+     value:: when rounding B to precision PREC with rounding mode RND,
+     a useful trick is the following: if (mpfr_can_round (b, err, MPFR_RNDN, MPFR_RNDZ, prec + (rnd == MPFR_RNDN)))
+        ...
+      Indeed, if RND is `MPFR_RNDN', this will check if one can round
+     to PREC+1 bits with a directed rounding: if so, one can surely
+     round to nearest to PREC bits, and in addition one can determine
+     the correct ternary value, which would not be the case when B is
+     near from a value exactly representable on PREC bits.
+
+ -- Function: mpfr_prec_t mpfr_min_prec (mpfr_t X)

+     the returned value can be less than `MPFR_PREC_MIN'.)
+
+     The function name is subject to change.
+
+ -- Function: const char * mpfr_print_rnd_mode (mpfr_rnd_t RND)

+ -- Function: int mpfr_max (mpfr_t ROP, mpfr_t OP1, mpfr_t OP2,
+          mpfr_rnd_t RND)
+     Set ROP to the minimum (resp. maximum) of OP1 and OP2. If OP1 and
+     OP2 are both NaN, then ROP is set to NaN. If OP1 or OP2 is NaN,
+     then ROP is set to the numeric value. If OP1 and OP2 are zeros of

+
+ -- Function: int mpfr_urandomb (mpfr_t ROP, gmp_randstate_t STATE)
+     Generate a uniformly distributed random float in the interval 0 <=
+     ROP < 1. More precisely, the number can be seen as a float with a
+     random non-normalized significand and exponent 0, which is then
+     normalized (thus if E denotes the exponent after normalization,
+     then the least -E significant bits of the significand are always
+     0).
+
+     Return 0, unless the exponent is not in the current exponent
+     range, in which case ROP is set to NaN and a non-zero value is
+     returned (this should never happen in practice, except in very
+     specific cases). The second argument is a `gmp_randstate_t'
+     structure which should be created using the GMP `gmp_randinit'
+     function (see the GMP manual).
+
+     Note: for a given version of MPFR, the returned value of ROP and
+     the new value of STATE (which controls further random values) do

+
+ -- Function: int mpfr_urandom (mpfr_t ROP, gmp_randstate_t STATE,
+          mpfr_rnd_t RND)
+     Generate a uniformly distributed random float.  The floating-point
+     number ROP can be seen as if a random real number is generated
+     according to the continuous uniform distribution on the interval
+     [0, 1] and then rounded in the direction RND.
+
+     The second argument is a `gmp_randstate_t' structure which should
+     be created using the GMP `gmp_randinit' function (see the GMP
+     manual).
+
+     Note: the note for `mpfr_urandomb' holds too. In addition, the

+
+ -- Function: int mpfr_grandom (mpfr_t ROP1, mpfr_t ROP2,
+          gmp_randstate_t STATE, mpfr_rnd_t RND)
+     Generate two random floats according to a standard normal gaussian
+     distribution. If ROP2 is a null pointer, then only one value is
+     generated and stored in ROP1.
+
+     The floating-point number ROP1 (and ROP2) can be seen as if a
+     random real number were generated according to the standard normal
+     gaussian distribution and then rounded in the direction RND.
+
+     The third argument is a `gmp_randstate_t' structure, which should
+     be created using the GMP `gmp_randinit' function (see the GMP
+     manual).
+
+     The combination of the ternary values is returned like with
+     `mpfr_sin_cos'. If ROP2 is a null pointer, the second ternary
+     value is assumed to be 0 (note that the encoding of the only
+     ternary value is not the same as the usual encoding for functions
+     that return only one result). Otherwise the ternary value of a
+     random number is always non-zero.
+
+     Note: the note for `mpfr_urandomb' holds too. In addition, the
+     exponent range and the rounding mode might have a side effect on
+     the next random state.
+
+ -- Function: mpfr_exp_t mpfr_get_exp (mpfr_t X)
+     Return the exponent of X, assuming that X is a non-zero ordinary
+     number and the significand is considered in [1/2,1). The behavior
+     for NaN, infinity or zero is undefined.
+
+ -- Function: int mpfr_set_exp (mpfr_t X, mpfr_exp_t E)
+     Set the exponent of X if E is in the current exponent range, and
+     return 0 (even if X is not a non-zero ordinary number); otherwise,
+     return a non-zero value.  The significand is assumed to be in
+     [1/2,1).
+
+ -- Function: int mpfr_signbit (mpfr_t OP)
+     Return a non-zero value iff OP has its sign bit set (i.e., if it is
+     negative, -0, or a NaN whose representation has its sign bit set).
+
+ -- Function: int mpfr_setsign (mpfr_t ROP, mpfr_t OP, int S,
+          mpfr_rnd_t RND)
+     Set the value of ROP from OP, rounded toward the given direction
+     RND, then set (resp. clear) its sign bit if S is non-zero (resp.
+     zero), even when OP is a NaN.
+
+ -- Function: int mpfr_copysign (mpfr_t ROP, mpfr_t OP1, mpfr_t OP2,
+          mpfr_rnd_t RND)
+     Set the value of ROP from OP1, rounded toward the given direction
+     RND, then set its sign bit to that of OP2 (even when OP1 or OP2 is
+     a NaN). This function is equivalent to `mpfr_setsign (ROP, OP1,
+     mpfr_signbit (OP2), RND)'.
+
+ -- Function: const char * mpfr_get_version (void)
+     Return the MPFR version, as a null-terminated string.
+
+ -- Macro: MPFR_VERSION
+ -- Macro: MPFR_VERSION_MAJOR
+ -- Macro: MPFR_VERSION_MINOR
+ -- Macro: MPFR_VERSION_PATCHLEVEL
+ -- Macro: MPFR_VERSION_STRING
+     `MPFR_VERSION' is the version of MPFR as a preprocessing constant.
+     `MPFR_VERSION_MAJOR', `MPFR_VERSION_MINOR' and
+     `MPFR_VERSION_PATCHLEVEL' are respectively the major, minor and
+     patch level of MPFR version, as preprocessing constants.
+     `MPFR_VERSION_STRING' is the version (with an optional suffix, used
+     in development and pre-release versions) as a string constant,
+     which can be compared to the result of `mpfr_get_version' to check
+     at run time the header file and library used match:
+          if (strcmp (mpfr_get_version (), MPFR_VERSION_STRING))
+            fprintf (stderr, "Warning: header and library do not match\n");
+     Note: Obtaining different strings is not necessarily an error, as
+     in general, a program compiled with some old MPFR version can be
+     dynamically linked with a newer MPFR library version (if allowed
+     by the library versioning system).
+
+ -- Macro: long MPFR_VERSION_NUM (MAJOR, MINOR, PATCHLEVEL)
+     Create an integer in the same format as used by `MPFR_VERSION'
+     from the given MAJOR, MINOR and PATCHLEVEL.  Here is an example of
+     how to check the MPFR version at compile time:
+          #if (!defined(MPFR_VERSION) || (MPFR_VERSION<MPFR_VERSION_NUM(3,0,0)))
+          # error "Wrong MPFR version."
+          #endif
+
+ -- Function: const char * mpfr_get_patches (void)
+     Return a null-terminated string containing the ids of the patches
+     applied to the MPFR library (contents of the `PATCHES' file),
+     separated by spaces.  Note: If the program has been compiled with
+     an older MPFR version and is dynamically linked with a new MPFR
+     library version, the identifiers of the patches applied to the old
+     (compile-time) MPFR version are not available (however this
+     information should not have much interest in general).
+
+ -- Function: int mpfr_buildopt_tls_p (void)
+     Return a non-zero value if MPFR was compiled as thread safe using
+     compiler-level Thread Local Storage (that is, MPFR was built with
+     the `--enable-thread-safe' configure option, see `INSTALL' file),
+     return zero otherwise.
+
+ -- Function: int mpfr_buildopt_decimal_p (void)
+     Return a non-zero value if MPFR was compiled with decimal float
+     support (that is, MPFR was built with the `--enable-decimal-float'
+     configure option), return zero otherwise.
+
+ -- Function: int mpfr_buildopt_gmpinternals_p (void)
+     Return a non-zero value if MPFR was compiled with GMP internals
+     (that is, MPFR was built with either `--with-gmp-build' or
+     `--enable-gmp-internals' configure option), return zero otherwise.
+
+ -- Function: const char * mpfr_buildopt_tune_case (void)
+     Return a string saying which thresholds file has been used at
+     compile time.  This file is normally selected from the processor
+     type.

+5.13 Exception Related Functions
+================================
+
+ -- Function: mpfr_exp_t mpfr_get_emin (void)
+ -- Function: mpfr_exp_t mpfr_get_emax (void)
+     Return the (current) smallest and largest exponents allowed for a
+     floating-point variable. The smallest positive value of a
+     floating-point variable is one half times 2 raised to the smallest
+     exponent and the largest value has the form (1 - epsilon) times 2
+     raised to the largest exponent, where epsilon depends on the
+     precision of the considered variable.
+
+ -- Function: int mpfr_set_emin (mpfr_exp_t EXP)
+ -- Function: int mpfr_set_emax (mpfr_exp_t EXP)
+     Set the smallest and largest exponents allowed for a
+     floating-point variable.  Return a non-zero value when EXP is not
+     in the range accepted by the implementation (in that case the
+     smallest or largest exponent is not changed), and zero otherwise.
+     If the user changes the exponent range, it is her/his
+     responsibility to check that all current floating-point variables
+     are in the new allowed range (for example using
+     `mpfr_check_range'), otherwise the subsequent behavior will be
+     undefined, in the sense of the ISO C standard.
+
+ -- Function: mpfr_exp_t mpfr_get_emin_min (void)
+ -- Function: mpfr_exp_t mpfr_get_emin_max (void)
+ -- Function: mpfr_exp_t mpfr_get_emax_min (void)
+ -- Function: mpfr_exp_t mpfr_get_emax_max (void)
+     Return the minimum and maximum of the exponents allowed for
+     `mpfr_set_emin' and `mpfr_set_emax' respectively.  These values
+     are implementation dependent, thus a program using
+     `mpfr_set_emax(mpfr_get_emax_max())' or
+     `mpfr_set_emin(mpfr_get_emin_min())' may not be portable.
+
+ -- Function: int mpfr_check_range (mpfr_t X, int T, mpfr_rnd_t RND)
+     This function assumes that X is the correctly-rounded value of some
+     real value Y in the direction RND and some extended exponent
+     range, and that T is the corresponding *note ternary value::.  For
+     example, one performed `t = mpfr_log (x, u, rnd)', and Y is the
+     exact logarithm of U.  Thus T is negative if X is smaller than Y,
+     positive if X is larger than Y, and zero if X equals Y.  This
+     function modifies X if needed to be in the current range of
+     acceptable values: It generates an underflow or an overflow if the
+     exponent of X is outside the current allowed range; the value of T
+     may be used to avoid a double rounding. This function returns zero
+     if the new value of X equals the exact one Y, a positive value if
+     that new value is larger than Y, and a negative value if it is
+     smaller than Y.  Note that unlike most functions, the new result X
+     is compared to the (unknown) exact one Y, not the input value X,
+     i.e., the ternary value is propagated.
+
+     Note: If X is an infinity and T is different from zero (i.e., if
+     the rounded result is an inexact infinity), then the overflow flag
+     is set. This is useful because `mpfr_check_range' is typically
+     called (at least in MPFR functions) after restoring the flags that
+     could have been set due to internal computations.
+
+ -- Function: int mpfr_subnormalize (mpfr_t X, int T, mpfr_rnd_t RND)
+     This function rounds X emulating subnormal number arithmetic: if X
+     is outside the subnormal exponent range, it just propagates the
+     *note ternary value:: T; otherwise, it rounds X to precision
+     `EXP(x)-emin+1' according to rounding mode RND and previous
+     ternary value T, avoiding double rounding problems.  More
+     precisely in the subnormal domain, denoting by E the value of
+     `emin', X is rounded in fixed-point arithmetic to an integer
+     multiple of two to the power E-1; as a consequence, 1.5 multiplied
+     by two to the power E-1 when T is zero is rounded to two to the
+     power E with rounding to nearest.
+
+     `PREC(x)' is not modified by this function.  RND and T must be the
+     rounding mode and the returned ternary value used when computing X
+     (as in `mpfr_check_range').  The subnormal exponent range is from
+     `emin' to `emin+PREC(x)-1'.  If the result cannot be represented
+     in the current exponent range (due to a too small `emax'), the
+     behavior is undefined.  Note that unlike most functions, the
+     result is compared to the exact one, not the input value X, i.e.,
+     the ternary value is propagated.
+
+     As usual, if the returned ternary value is non zero, the inexact
+     flag is set.  Moreover, if a second rounding occurred (because the
+     input X was in the subnormal range), the underflow flag is set.
+
+   This is an example of how to emulate binary double IEEE 754
+arithmetic (binary64 in IEEE 754-2008) using MPFR:
+
+     {
+       mpfr_t xa, xb; int i; volatile double a, b;
+
+       mpfr_set_default_prec (53);
+       mpfr_set_emin (-1073); mpfr_set_emax (1024);
+
+       mpfr_init (xa); mpfr_init (xb);
+
+       b = 34.3; mpfr_set_d (xb, b, MPFR_RNDN);
+       a = 0x1.1235P-1021; mpfr_set_d (xa, a, MPFR_RNDN);
+
+       a /= b;
+       i = mpfr_div (xa, xa, xb, MPFR_RNDN);
+       i = mpfr_subnormalize (xa, i, MPFR_RNDN); /* new ternary value */
+
+       mpfr_clear (xa); mpfr_clear (xb);
+     }
+
+   Warning: this emulates a double IEEE 754 arithmetic with correct
+rounding in the subnormal range, which may not be the case for your
+hardware.

+
+5.14 Compatibility With MPF
+===========================
+
+A header file `mpf2mpfr.h' is included in the distribution of MPFR for
+compatibility with the GNU MP class MPF.  By inserting the following
+two lines after the `#include <gmp.h>' line,
+#include <mpfr.h>
+#include <mpf2mpfr.h>
+ any program written for MPF can be compiled directly with MPFR without
+any changes (except the `gmp_printf' functions will not work for
+arguments of type `mpfr_t').  All operations are then performed with
+the default MPFR rounding mode, which can be reset with
+`mpfr_set_default_rounding_mode'.
+
+   Warning: the `mpf_init' and `mpf_init2' functions initialize to
+zero, whereas the corresponding MPFR functions initialize to NaN: this
+is useful to detect uninitialized values, but is slightly incompatible
+with MPF.
+
+ -- Function: void mpfr_set_prec_raw (mpfr_t X, mpfr_prec_t PREC)
+     Reset the precision of X to be *exactly* PREC bits.  The only
+     difference with `mpfr_set_prec' is that PREC is assumed to be
+     small enough so that the significand fits into the current
+     allocated memory space for X. Otherwise the behavior is undefined.
+
+ -- Function: int mpfr_eq (mpfr_t OP1, mpfr_t OP2, unsigned long int
+          OP3)
+     Return non-zero if OP1 and OP2 are both non-zero ordinary numbers
+     with the same exponent and the same first OP3 bits, both zero, or
+     both infinities of the same sign. Return zero otherwise.  This
+     function is defined for compatibility with MPF, we do not recommend
+     to use it otherwise.  Do not use it either if you want to know
+     whether two numbers are close to each other; for instance,
+     1.011111 and 1.100000 are regarded as different for any value of
+     OP3 larger than 1.
+
+ -- Function: void mpfr_reldiff (mpfr_t ROP, mpfr_t OP1, mpfr_t OP2,
+          mpfr_rnd_t RND)
+     Compute the relative difference between OP1 and OP2 and store the
+     result in ROP.  This function does not guarantee the correct
+     rounding on the relative difference; it just computes
+     |OP1-OP2|/OP1, using the precision of ROP and the rounding mode
+     RND for all operations.
+
+ -- Function: int mpfr_mul_2exp (mpfr_t ROP, mpfr_t OP1, unsigned long
+          int OP2, mpfr_rnd_t RND)
+ -- Function: int mpfr_div_2exp (mpfr_t ROP, mpfr_t OP1, unsigned long
+          int OP2, mpfr_rnd_t RND)
+     These functions are identical to `mpfr_mul_2ui' and `mpfr_div_2ui'
+     respectively.  These functions are only kept for compatibility
+     with MPF, one should prefer `mpfr_mul_2ui' and `mpfr_div_2ui'
+     otherwise.

+File: mpfr.info,  Node: Custom Interface,  Next: Internals,  Prev: Compatibility with MPF,  Up: MPFR Interface
+
+5.15 Custom Interface
+=====================
+
+Some applications use a stack to handle the memory and their objects.
+However, the MPFR memory design is not well suited for such a thing. So
+that such applications are able to use MPFR, an auxiliary memory
+interface has been created: the Custom Interface.
+
+   The following interface allows one to use MPFR in two ways:
+   * Either directly store a floating-point number as a `mpfr_t' on the
+     stack.
+
+   * Either store its own representation on the stack and construct a
+     new temporary `mpfr_t' each time it is needed.
+   Nothing has to be done to destroy the floating-point numbers except
+garbaging the used memory: all the memory management (allocating,
+destroying, garbaging) is left to the application.
+
+   Each function in this interface is also implemented as a macro for
+efficiency reasons: for example `mpfr_custom_init (s, p)' uses the
+macro, while `(mpfr_custom_init) (s, p)' uses the function.
+
+   Note 1: MPFR functions may still initialize temporary floating-point
+numbers using `mpfr_init' and similar functions. See Custom Allocation
+(GNU MP).
+
+   Note 2: MPFR functions may use the cached functions (`mpfr_const_pi'
+for example), even if they are not explicitly called. You have to call
+`mpfr_free_cache' each time you garbage the memory iff `mpfr_init',
+through GMP Custom Allocation, allocates its memory on the application
+stack.
+
+ -- Function: size_t mpfr_custom_get_size (mpfr_prec_t PREC)
+     Return the needed size in bytes to store the significand of a
+     floating-point number of precision PREC.
+
+ -- Function: void mpfr_custom_init (void *SIGNIFICAND, mpfr_prec_t
+          PREC)
+     Initialize a significand of precision PREC, where SIGNIFICAND must
+     be an area of `mpfr_custom_get_size (prec)' bytes at least and be
+     suitably aligned for an array of `mp_limb_t' (GMP type, *note
+     Internals::).
+
+ -- Function: void mpfr_custom_init_set (mpfr_t X, int KIND, mpfr_exp_t
+          EXP, mpfr_prec_t PREC, void *SIGNIFICAND)
+     Perform a dummy initialization of a `mpfr_t' and set it to:
+        * if `ABS(kind) == MPFR_NAN_KIND', X is set to NaN;
+
+        * if `ABS(kind) == MPFR_INF_KIND', X is set to the infinity of
+          sign `sign(kind)';
+
+        * if `ABS(kind) == MPFR_ZERO_KIND', X is set to the zero of
+          sign `sign(kind)';
+
+        * if `ABS(kind) == MPFR_REGULAR_KIND', X is set to a regular
+          number: `x = sign(kind)*significand*2^exp'.
+     In all cases, it uses SIGNIFICAND directly for further computing
+     involving X. It will not allocate anything.  A floating-point
+     number initialized with this function cannot be resized using
+     `mpfr_set_prec' or `mpfr_prec_round', or cleared using
+     `mpfr_clear'!  The SIGNIFICAND must have been initialized with
+     `mpfr_custom_init' using the same precision PREC.
+
+ -- Function: int mpfr_custom_get_kind (mpfr_t X)
+     Return the current kind of a `mpfr_t' as created by
+     `mpfr_custom_init_set'.  The behavior of this function for any
+     `mpfr_t' not initialized with `mpfr_custom_init_set' is undefined.
+
+ -- Function: void * mpfr_custom_get_significand (mpfr_t X)
+     Return a pointer to the significand used by a `mpfr_t' initialized
+     with `mpfr_custom_init_set'.  The behavior of this function for
+     any `mpfr_t' not initialized with `mpfr_custom_init_set' is
+     undefined.
+
+ -- Function: mpfr_exp_t mpfr_custom_get_exp (mpfr_t X)
+     Return the exponent of X, assuming that X is a non-zero ordinary
+     number. The return value for NaN, Infinity or zero is unspecified
+     but does not produce any trap.  The behavior of this function for
+     any `mpfr_t' not initialized with `mpfr_custom_init_set' is
+     undefined.
+
+ -- Function: void mpfr_custom_move (mpfr_t X, void *NEW_POSITION)
+     Inform MPFR that the significand of X has moved due to a garbage
+     collect and update its new position to `new_position'.  However
+     the application has to move the significand and the `mpfr_t'
+     itself.  The behavior of this function for any `mpfr_t' not
+     initialized with `mpfr_custom_init_set' is undefined.

+5.16 Internals
+==============
+
+A "limb" means the part of a multi-precision number that fits in a
+single word. Usually a limb contains 32 or 64 bits.  The C data type
+for a limb is `mp_limb_t'.
+
+   The `mpfr_t' type is internally defined as a one-element array of a
+structure, and `mpfr_ptr' is the C data type representing a pointer to
+this structure.  The `mpfr_t' type consists of four fields:
+
+   * The `_mpfr_prec' field is used to store the precision of the
+     variable (in bits); this is not less than `MPFR_PREC_MIN'.
+
+   * The `_mpfr_sign' field is used to store the sign of the variable.
+
+   * The `_mpfr_exp' field stores the exponent.  An exponent of 0 means
+     a radix point just above the most significant limb.  Non-zero
+     values n are a multiplier 2^n relative to that point.  A NaN, an
+     infinity and a zero are indicated by special values of the exponent
+     field.
+
+   * Finally, the `_mpfr_d' field is a pointer to the limbs, least
+     significant limbs stored first.  The number of limbs in use is
+     controlled by `_mpfr_prec', namely
+     ceil(`_mpfr_prec'/`mp_bits_per_limb').  Non-singular (i.e.,
+     different from NaN, Infinity or zero) values always have the most
+     significant bit of the most significant limb set to 1.  When the
+     precision does not correspond to a whole number of limbs, the
+     excess bits at the low end of the data are zeros.

+6 API Compatibility
+*******************
+
+The goal of this section is to describe some API changes that occurred
+from one version of MPFR to another, and how to write code that can be
+compiled and run with older MPFR versions.  The minimum MPFR version
+that is considered here is 2.2.0 (released on 20 September 2005).
+
+   API changes can only occur between major or minor versions.  Thus the
+patchlevel (the third number in the MPFR version) will be ignored in
+the following.  If a program does not use MPFR internals, changes in
+the behavior between two versions differing only by the patchlevel
+should only result from what was regarded as a bug or unspecified
+behavior.
+
+   As a general rule, a program written for some MPFR version should
+work with later versions, possibly except at a new major version, where
+some features (described as obsolete for some time) can be removed.  In
+such a case, a failure should occur during compilation or linking.  If
+a result becomes incorrect because of such a change, please look at the
+various changes below (they are minimal, and most software should be
+unaffected), at the FAQ and at the MPFR web page for your version (a
+bug could have been introduced and be already fixed); and if the
+problem is not mentioned, please send us a bug report (*note Reporting
+Bugs::).
+
+   However, a program written for the current MPFR version (as
+documented by this manual) may not necessarily work with previous
+versions of MPFR.  This section should help developers to write
+portable code.
+
+   Note: Information given here may be incomplete.  API changes are
+also described in the NEWS file (for each version, instead of being
+classified like here), together with other changes.

+6.1 Type and Macro Changes
+==========================
+
+The official type for exponent values changed from `mp_exp_t' to
+`mpfr_exp_t' in MPFR 3.0.  The type `mp_exp_t' will remain available as
+it comes from GMP (with a different meaning).  These types are
+currently the same (`mpfr_exp_t' is defined as `mp_exp_t' with
+`typedef'), so that programs can still use `mp_exp_t'; but this may
+change in the future.  Alternatively, using the following code after
+including `mpfr.h' will work with official MPFR versions, as
+`mpfr_exp_t' was never defined in MPFR 2.x:
+     #if MPFR_VERSION_MAJOR < 3
+     typedef mp_exp_t mpfr_exp_t;
+     #endif
+
+   The official types for precision values and for rounding modes
+respectively changed from `mp_prec_t' and `mp_rnd_t' to `mpfr_prec_t'
+and `mpfr_rnd_t' in MPFR 3.0.  This change was actually done a long
+time ago in MPFR, at least since MPFR 2.2.0, with the following code in
+`mpfr.h':
+     #ifndef mp_rnd_t
+     # define mp_rnd_t  mpfr_rnd_t
+     #endif
+     #ifndef mp_prec_t
+     # define mp_prec_t mpfr_prec_t
+     #endif
+   This means that it is safe to use the new official types
+`mpfr_prec_t' and `mpfr_rnd_t' in your programs.  The types `mp_prec_t'
+and `mp_rnd_t' (defined in MPFR only) may be removed in the future, as
+the prefix `mp_' is reserved by GMP.
+
+   The precision type `mpfr_prec_t' (`mp_prec_t') was unsigned before
+MPFR 3.0; it is now signed.  `MPFR_PREC_MAX' has not changed, though.
+Indeed the MPFR code requires that `MPFR_PREC_MAX' be representable in
+the exponent type, which may have the same size as `mpfr_prec_t' but
+has always been signed.  The consequence is that valid code that does
+not assume anything about the signedness of `mpfr_prec_t' should work
+with past and new MPFR versions.  This change was useful as the use of
+unsigned types tends to convert signed values to unsigned ones in
+expressions due to the usual arithmetic conversions, which can yield
+incorrect results if a negative value is converted in such a way.
+Warning!  A program assuming (intentionally or not) that `mpfr_prec_t'
+is signed may be affected by this problem when it is built and run
+against MPFR 2.x.
+
+   The rounding modes `GMP_RNDx' were renamed to `MPFR_RNDx' in MPFR
+3.0. However the old names `GMP_RNDx' have been kept for compatibility
+(this might change in future versions), using:
+     #define GMP_RNDN MPFR_RNDN
+     #define GMP_RNDZ MPFR_RNDZ
+     #define GMP_RNDU MPFR_RNDU
+     #define GMP_RNDD MPFR_RNDD
+   The rounding mode "round away from zero" (`MPFR_RNDA') was added in
+MPFR 3.0 (however no rounding mode `GMP_RNDA' exists).

+
+6.2 Added Functions
+===================
+
+We give here in alphabetical order the functions that were added after
+MPFR 2.2, and in which MPFR version.
+
+   * `mpfr_add_d' in MPFR 2.4.
+
+   * `mpfr_ai' in MPFR 3.0 (incomplete, experimental).
+
+   * `mpfr_asprintf' in MPFR 2.4.
+
+   * `mpfr_buildopt_decimal_p' and `mpfr_buildopt_tls_p' in MPFR 3.0.
+
+   * `mpfr_buildopt_gmpinternals_p' and `mpfr_buildopt_tune_case' in
+     MPFR 3.1.
+
+   * `mpfr_clear_divby0' in MPFR 3.1 (new divide-by-zero exception).
+
+   * `mpfr_copysign' in MPFR 2.3.  Note: MPFR 2.2 had a `mpfr_copysign'
+     function that was available, but not documented, and with a slight
+     difference in the semantics (when the second input operand is a
+     NaN).
+
+   * `mpfr_custom_get_significand' in MPFR 3.0.  This function was
+     named `mpfr_custom_get_mantissa' in previous versions;
+     `mpfr_custom_get_mantissa' is still available via a macro in
+     `mpfr.h':
+          #define mpfr_custom_get_mantissa mpfr_custom_get_significand
+     Thus code that needs to work with both MPFR 2.x and MPFR 3.x should
+     use `mpfr_custom_get_mantissa'.
+
+   * `mpfr_d_div' and `mpfr_d_sub' in MPFR 2.4.
+
+   * `mpfr_digamma' in MPFR 3.0.
+
+   * `mpfr_divby0_p' in MPFR 3.1 (new divide-by-zero exception).
+
+   * `mpfr_div_d' in MPFR 2.4.
+
+   * `mpfr_fmod' in MPFR 2.4.
+
+   * `mpfr_fms' in MPFR 2.3.
+
+   * `mpfr_fprintf' in MPFR 2.4.
+
+   * `mpfr_frexp' in MPFR 3.1.
+
+   * `mpfr_get_flt' in MPFR 3.0.
+
+   * `mpfr_get_patches' in MPFR 2.3.
+
+   * `mpfr_get_z_2exp' in MPFR 3.0.  This function was named
+     `mpfr_get_z_exp' in previous versions; `mpfr_get_z_exp' is still
+     available via a macro in `mpfr.h':
+          #define mpfr_get_z_exp mpfr_get_z_2exp
+     Thus code that needs to work with both MPFR 2.x and MPFR 3.x should
+     use `mpfr_get_z_exp'.
+
+   * `mpfr_grandom' in MPFR 3.1.
+
+   * `mpfr_j0', `mpfr_j1' and `mpfr_jn' in MPFR 2.3.
+
+   * `mpfr_lgamma' in MPFR 2.3.
+
+   * `mpfr_li2' in MPFR 2.4.
+
+   * `mpfr_min_prec' in MPFR 3.0.
+
+   * `mpfr_modf' in MPFR 2.4.
+
+   * `mpfr_mul_d' in MPFR 2.4.
+
+   * `mpfr_printf' in MPFR 2.4.
+
+   * `mpfr_rec_sqrt' in MPFR 2.4.
+
+   * `mpfr_regular_p' in MPFR 3.0.
+
+   * `mpfr_remainder' and `mpfr_remquo' in MPFR 2.3.
+
+   * `mpfr_set_divby0' in MPFR 3.1 (new divide-by-zero exception).
+
+   * `mpfr_set_flt' in MPFR 3.0.
+
+   * `mpfr_set_z_2exp' in MPFR 3.0.
+
+   * `mpfr_set_zero' in MPFR 3.0.
+
+   * `mpfr_setsign' in MPFR 2.3.
+
+   * `mpfr_signbit' in MPFR 2.3.
+
+   * `mpfr_sinh_cosh' in MPFR 2.4.
+
+   * `mpfr_snprintf' and `mpfr_sprintf' in MPFR 2.4.
+
+   * `mpfr_sub_d' in MPFR 2.4.
+
+   * `mpfr_urandom' in MPFR 3.0.
+
+   * `mpfr_vasprintf', `mpfr_vfprintf', `mpfr_vprintf',
+     `mpfr_vsprintf' and `mpfr_vsnprintf' in MPFR 2.4.
+
+   * `mpfr_y0', `mpfr_y1' and `mpfr_yn' in MPFR 2.3.

+
+6.3 Changed Functions
+=====================
+
+The following functions have changed after MPFR 2.2. Changes can affect
+the behavior of code written for some MPFR version when built and run
+against another MPFR version (older or newer), as described below.
+
+   * `mpfr_check_range' changed in MPFR 2.3.2 and MPFR 2.4.  If the
+     value is an inexact infinity, the overflow flag is now set (in
+     case it was lost), while it was previously left unchanged.  This
+     is really what is expected in practice (and what the MPFR code was
+     expecting), so that the previous behavior was regarded as a bug.
+     Hence the change in MPFR 2.3.2.
+
+   * `mpfr_get_f' changed in MPFR 3.0.  This function was returning
+     zero, except for NaN and Inf, which do not exist in MPF. The
+     _erange_ flag is now set in these cases, and `mpfr_get_f' now
+     returns the usual ternary value.
+
+   * `mpfr_get_si', `mpfr_get_sj', `mpfr_get_ui' and `mpfr_get_uj'
+     changed in MPFR 3.0.  In previous MPFR versions, the cases where
+     the _erange_ flag is set were unspecified.
+
+   * `mpfr_get_z' changed in MPFR 3.0.  The return type was `void'; it
+     is now `int', and the usual ternary value is returned.  Thus
+     programs that need to work with both MPFR 2.x and 3.x must not use
+     the return value.  Even in this case, C code using `mpfr_get_z' as
+     the second or third term of a conditional operator may also be
+     affected. For instance, the following is correct with MPFR 3.0,
+     but not with MPFR 2.x:
+            bool ? mpfr_get_z(...) : mpfr_add(...);
+     On the other hand, the following is correct with MPFR 2.x, but not
+     with MPFR 3.0:
+            bool ? mpfr_get_z(...) : (void) mpfr_add(...);
+     Portable code should cast `mpfr_get_z(...)' to `void' to use the
+     type `void' for both terms of the conditional operator, as in:
+            bool ? (void) mpfr_get_z(...) : (void) mpfr_add(...);
+     Alternatively, `if ... else' can be used instead of the
+     conditional operator.
+
+     Moreover the cases where the _erange_ flag is set were unspecified
+     in MPFR 2.x.
+
+   * `mpfr_get_z_exp' changed in MPFR 3.0.  In previous MPFR versions,
+     the cases where the _erange_ flag is set were unspecified.  Note:
+     this function has been renamed to `mpfr_get_z_2exp' in MPFR 3.0,
+     but `mpfr_get_z_exp' is still available for compatibility reasons.
+
+   * `mpfr_strtofr' changed in MPFR 2.3.1 and MPFR 2.4.  This was
+     actually a bug fix since the code and the documentation did not
+     match.  But both were changed in order to have a more consistent
+     and useful behavior.  The main changes in the code are as follows.
+     The binary exponent is now accepted even without the `0b' or `0x'
+     prefix.  Data corresponding to NaN can now have an optional sign
+     (such data were previously invalid).
+
+   * `mpfr_strtofr' changed in MPFR 3.0.  This function now accepts
+     bases from 37 to 62 (no changes for the other bases).  Note: if an
+     unsupported base is provided to this function, the behavior is
+     undefined; more precisely, in MPFR 2.3.1 and later, providing an
+     unsupported base yields an assertion failure (this behavior may
+     change in the future).
+
+   * `mpfr_subnormalize' changed in MPFR 3.1.  This was actually
+     regarded as a bug fix. The `mpfr_subnormalize' implementation up
+     to MPFR 3.0.0 did not change the flags. In particular, it did not
+     follow the generic rule concerning the inexact flag (and no
+     special behavior was specified). The case of the underflow flag
+     was more a lack of specification.
+
+   * `mpfr_urandom' and `mpfr_urandomb' changed in MPFR 3.1.  Their
+     behavior no longer depends on the platform (assuming this is also
+     true for GMP's random generator, which is not the case between GMP
+     4.1 and 4.2 if `gmp_randinit_default' is used).  As a consequence,
+     the returned values can be different between MPFR 3.1 and previous
+     MPFR versions.  Note: as the reproducibility of these functions
+     was not specified before MPFR 3.1, the MPFR 3.1 behavior is _not_
+     regarded as backward incompatible with previous versions.

+
+6.4 Removed Functions
+=====================
+
+Functions `mpfr_random' and `mpfr_random2' have been removed in MPFR
+3.0 (this only affects old code built against MPFR 3.0 or later).  (The
+function `mpfr_random' had been deprecated since at least MPFR 2.2.0,
+and `mpfr_random2' since MPFR 2.4.0.)
+
+
+File: mpfr.info,  Node: Other Changes,  Prev: Removed Functions,  Up: API Compatibility
+
+6.5 Other Changes
+=================
+
+For users of a C++ compiler, the way how the availability of `intmax_t'
+is detected has changed in MPFR 3.0.  In MPFR 2.x, if a macro
+`INTMAX_C' or `UINTMAX_C' was defined (e.g. when the
+`__STDC_CONSTANT_MACROS' macro had been defined before `<stdint.h>' or
+`<inttypes.h>' has been included), `intmax_t' was assumed to be defined.
+However this was not always the case (more precisely, `intmax_t' can be
+defined only in the namespace `std', as with Boost), so that
+compilations could fail.  Thus the check for `INTMAX_C' or `UINTMAX_C'
+is now disabled for C++ compilers, with the following consequences:
+
+   * Programs written for MPFR 2.x that need `intmax_t' may no longer
+     be compiled against MPFR 3.0: a `#define MPFR_USE_INTMAX_T' may be
+     necessary before `mpfr.h' is included.
+
+   * The compilation of programs that work with MPFR 3.0 may fail with
+     MPFR 2.x due to the problem described above.  Workarounds are
+     possible, such as defining `intmax_t' and `uintmax_t' in the global
+     namespace, though this is not clean.
+
+
+   The divide-by-zero exception is new in MPFR 3.1. However it should
+not introduce incompatible changes for programs that strictly follow
+the MPFR API since the exception can only be seen via new functions.
+
+   As of MPFR 3.1, the `mpfr.h' header can be included several times,
+while still supporting optional functions (*note Headers and
+Libraries::).

+Contributors
+************
+
+The main developers of MPFR are Guillaume Hanrot, Vincent Lefèvre,
+Patrick Pélissier, Philippe Théveny and Paul Zimmermann.
+
+   Sylvie Boldo from ENS-Lyon, France, contributed the functions
+`mpfr_agm' and `mpfr_log'.  Sylvain Chevillard contributed the
+`mpfr_ai' function.  David Daney contributed the hyperbolic and inverse
+hyperbolic functions, the base-2 exponential, and the factorial
+function.  Alain Delplanque contributed the new version of the
+`mpfr_get_str' function.  Mathieu Dutour contributed the functions
+`mpfr_acos', `mpfr_asin' and `mpfr_atan', and a previous version of
+`mpfr_gamma'.  Laurent Fousse contributed the `mpfr_sum' function.
+Emmanuel Jeandel, from ENS-Lyon too, contributed the generic
+hypergeometric code, as well as the internal function `mpfr_exp3', a
+first implementation of the sine and cosine, and improved versions of
+`mpfr_const_log2' and `mpfr_const_pi'.  Ludovic Meunier helped in the
+design of the `mpfr_erf' code.  Jean-Luc Rémy contributed the
+`mpfr_zeta' code.  Fabrice Rouillier contributed the `mpfr_xxx_z' and
+`mpfr_xxx_q' functions, and helped to the Microsoft Windows porting.
+Damien Stehlé contributed the `mpfr_get_ld_2exp' function.
+
+   We would like to thank Jean-Michel Muller and Joris van der Hoeven
+for very fruitful discussions at the beginning of that project,
+Torbjörn Granlund and Kevin Ryde for their help about design issues,
+and Nathalie Revol for her careful reading of a previous version of
+this documentation. In particular Kevin Ryde did a tremendous job for
+the portability of MPFR in 2002-2004.
+
+   The development of the MPFR library would not have been possible
+without the continuous support of INRIA, and of the LORIA (Nancy,
+France) and LIP (Lyon, France) laboratories. In particular the main
+authors were or are members of the PolKA, Spaces, Cacao and Caramel
+project-teams at LORIA and of the Arénaire and AriC project-teams at
+LIP.  This project was started during the Fiable (reliable in French)
+action supported by INRIA, and continued during the AOC action.  The
+development of MPFR was also supported by a grant (202F0659 00 MPN 121)
+from the Conseil Régional de Lorraine in 2002, from INRIA by an
+"associate engineer" grant (2003-2005), an "opération de développement
+logiciel" grant (2007-2009), and the post-doctoral grant of Sylvain
+Chevillard in 2009-2010.  The MPFR-MPC workshop in June 2012 was partly
+supported by the ERC grant ANTICS of Andreas Enge.

+
+  0. PREAMBLE
+
+     The purpose of this License is to make a manual, textbook, or other
+     functional and useful document "free" in the sense of freedom: to
+     assure everyone the effective freedom to copy and redistribute it,
+     with or without modifying it, either commercially or
+     noncommercially.  Secondarily, this License preserves for the
+     author and publisher a way to get credit for their work, while not
+     being considered responsible for modifications made by others.
+
+     This License is a kind of "copyleft", which means that derivative
+     works of the document must themselves be free in the same sense.
+     It complements the GNU General Public License, which is a copyleft
+     license designed for free software.
+
+     We have designed this License in order to use it for manuals for
+     free software, because free software needs free documentation: a
+     free program should come with manuals providing the same freedoms
+     that the software does.  But this License is not limited to
+     software manuals; it can be used for any textual work, regardless
+     of subject matter or whether it is published as a printed book.
+     We recommend this License principally for works whose purpose is
+     instruction or reference.
+
+  1. APPLICABILITY AND DEFINITIONS
+
+     This License applies to any manual or other work, in any medium,
+     that contains a notice placed by the copyright holder saying it
+     can be distributed under the terms of this License.  Such a notice
+     grants a world-wide, royalty-free license, unlimited in duration,
+     to use that work under the conditions stated herein.  The
+     "Document", below, refers to any such manual or work.  Any member
+     of the public is a licensee, and is addressed as "you".  You
+     accept the license if you copy, modify or distribute the work in a
+     way requiring permission under copyright law.
+
+     A "Modified Version" of the Document means any work containing the
+     Document or a portion of it, either copied verbatim, or with
+     modifications and/or translated into another language.
+
+     A "Secondary Section" is a named appendix or a front-matter section
+     of the Document that deals exclusively with the relationship of the
+     publishers or authors of the Document to the Document's overall
+     subject (or to related matters) and contains nothing that could
+     fall directly within that overall subject.  (Thus, if the Document
+     is in part a textbook of mathematics, a Secondary Section may not
+     explain any mathematics.)  The relationship could be a matter of
+     historical connection with the subject or with related matters, or
+     of legal, commercial, philosophical, ethical or political position
+     regarding them.
+
+     The "Invariant Sections" are certain Secondary Sections whose
+     titles are designated, as being those of Invariant Sections, in
+     the notice that says that the Document is released under this
+     License.  If a section does not fit the above definition of
+     Secondary then it is not allowed to be designated as Invariant.
+     The Document may contain zero Invariant Sections.  If the Document
+     does not identify any Invariant Sections then there are none.
+
+     The "Cover Texts" are certain short passages of text that are
+     listed, as Front-Cover Texts or Back-Cover Texts, in the notice
+     that says that the Document is released under this License.  A
+     Front-Cover Text may be at most 5 words, and a Back-Cover Text may
+     be at most 25 words.
+
+     A "Transparent" copy of the Document means a machine-readable copy,
+     represented in a format whose specification is available to the
+     general public, that is suitable for revising the document
+     straightforwardly with generic text editors or (for images
+     composed of pixels) generic paint programs or (for drawings) some
+     widely available drawing editor, and that is suitable for input to
+     text formatters or for automatic translation to a variety of
+     formats suitable for input to text formatters.  A copy made in an
+     otherwise Transparent file format whose markup, or absence of
+     markup, has been arranged to thwart or discourage subsequent
+     modification by readers is not Transparent.  An image format is
+     not Transparent if used for any substantial amount of text.  A
+     copy that is not "Transparent" is called "Opaque".
+
+     Examples of suitable formats for Transparent copies include plain
+     ASCII without markup, Texinfo input format, LaTeX input format,
+     SGML or XML using a publicly available DTD, and
+     standard-conforming simple HTML, PostScript or PDF designed for
+     human modification.  Examples of transparent image formats include
+     PNG, XCF and JPG.  Opaque formats include proprietary formats that
+     can be read and edited only by proprietary word processors, SGML or
+     XML for which the DTD and/or processing tools are not generally
+     available, and the machine-generated HTML, PostScript or PDF
+     produced by some word processors for output purposes only.
+
+     The "Title Page" means, for a printed book, the title page itself,
+     plus such following pages as are needed to hold, legibly, the
+     material this License requires to appear in the title page.  For
+     works in formats which do not have any title page as such, "Title
+     Page" means the text near the most prominent appearance of the
+     work's title, preceding the beginning of the body of the text.
+
+     A section "Entitled XYZ" means a named subunit of the Document
+     whose title either is precisely XYZ or contains XYZ in parentheses
+     following text that translates XYZ in another language.  (Here XYZ
+     stands for a specific section name mentioned below, such as
+     "Acknowledgements", "Dedications", "Endorsements", or "History".)
+     To "Preserve the Title" of such a section when you modify the
+     Document means that it remains a section "Entitled XYZ" according
+     to this definition.
+
+     The Document may include Warranty Disclaimers next to the notice
+     which states that this License applies to the Document.  These
+     Warranty Disclaimers are considered to be included by reference in
+     this License, but only as regards disclaiming warranties: any other
+     implication that these Warranty Disclaimers may have is void and
+     has no effect on the meaning of this License.
+
+  2. VERBATIM COPYING
+
+     You may copy and distribute the Document in any medium, either
+     commercially or noncommercially, provided that this License, the
+     copyright notices, and the license notice saying this License
+     applies to the Document are reproduced in all copies, and that you
+     add no other conditions whatsoever to those of this License.  You
+     may not use technical measures to obstruct or control the reading
+     or further copying of the copies you make or distribute.  However,
+     you may accept compensation in exchange for copies.  If you
+     distribute a large enough number of copies you must also follow
+     the conditions in section 3.
+
+     You may also lend copies, under the same conditions stated above,
+     and you may publicly display copies.
+
+  3. COPYING IN QUANTITY
+
+     If you publish printed copies (or copies in media that commonly
+     have printed covers) of the Document, numbering more than 100, and
+     the Document's license notice requires Cover Texts, you must
+     enclose the copies in covers that carry, clearly and legibly, all
+     these Cover Texts: Front-Cover Texts on the front cover, and
+     Back-Cover Texts on the back cover.  Both covers must also clearly
+     and legibly identify you as the publisher of these copies.  The
+     front cover must present the full title with all words of the
+     title equally prominent and visible.  You may add other material
+     on the covers in addition.  Copying with changes limited to the
+     covers, as long as they preserve the title of the Document and
+     satisfy these conditions, can be treated as verbatim copying in
+     other respects.
+
+     If the required texts for either cover are too voluminous to fit
+     legibly, you should put the first ones listed (as many as fit
+     reasonably) on the actual cover, and continue the rest onto
+     adjacent pages.
+
+     If you publish or distribute Opaque copies of the Document
+     numbering more than 100, you must either include a
+     machine-readable Transparent copy along with each Opaque copy, or
+     state in or with each Opaque copy a computer-network location from
+     which the general network-using public has access to download
+     using public-standard network protocols a complete Transparent
+     copy of the Document, free of added material.  If you use the
+     latter option, you must take reasonably prudent steps, when you
+     begin distribution of Opaque copies in quantity, to ensure that
+     this Transparent copy will remain thus accessible at the stated
+     location until at least one year after the last time you
+     distribute an Opaque copy (directly or through your agents or
+     retailers) of that edition to the public.
+
+     It is requested, but not required, that you contact the authors of
+     the Document well before redistributing any large number of
+     copies, to give them a chance to provide you with an updated
+     version of the Document.
+
+  4. MODIFICATIONS
+
+     You may copy and distribute a Modified Version of the Document
+     under the conditions of sections 2 and 3 above, provided that you
+     release the Modified Version under precisely this License, with
+     the Modified Version filling the role of the Document, thus
+     licensing distribution and modification of the Modified Version to
+     whoever possesses a copy of it.  In addition, you must do these
+     things in the Modified Version:
+
+       A. Use in the Title Page (and on the covers, if any) a title
+          distinct from that of the Document, and from those of
+          previous versions (which should, if there were any, be listed
+          in the History section of the Document).  You may use the
+          same title as a previous version if the original publisher of
+          that version gives permission.
+
+       B. List on the Title Page, as authors, one or more persons or
+          entities responsible for authorship of the modifications in
+          the Modified Version, together with at least five of the
+          principal authors of the Document (all of its principal
+          authors, if it has fewer than five), unless they release you
+          from this requirement.
+
+       C. State on the Title page the name of the publisher of the
+          Modified Version, as the publisher.
+
+       D. Preserve all the copyright notices of the Document.
+
+       E. Add an appropriate copyright notice for your modifications
+          adjacent to the other copyright notices.
+
+       F. Include, immediately after the copyright notices, a license
+          notice giving the public permission to use the Modified
+          Version under the terms of this License, in the form shown in
+          the Addendum below.
+
+       G. Preserve in that license notice the full lists of Invariant
+          Sections and required Cover Texts given in the Document's
+          license notice.
+
+       H. Include an unaltered copy of this License.
+
+       I. Preserve the section Entitled "History", Preserve its Title,
+          and add to it an item stating at least the title, year, new
+          authors, and publisher of the Modified Version as given on
+          the Title Page.  If there is no section Entitled "History" in
+          the Document, create one stating the title, year, authors,
+          and publisher of the Document as given on its Title Page,
+          then add an item describing the Modified Version as stated in
+          the previous sentence.
+
+       J. Preserve the network location, if any, given in the Document
+          for public access to a Transparent copy of the Document, and
+          likewise the network locations given in the Document for
+          previous versions it was based on.  These may be placed in
+          the "History" section.  You may omit a network location for a
+          work that was published at least four years before the
+          Document itself, or if the original publisher of the version
+          it refers to gives permission.
+
+       K. For any section Entitled "Acknowledgements" or "Dedications",
+          Preserve the Title of the section, and preserve in the
+          section all the substance and tone of each of the contributor
+          acknowledgements and/or dedications given therein.
+
+       L. Preserve all the Invariant Sections of the Document,
+          unaltered in their text and in their titles.  Section numbers
+          or the equivalent are not considered part of the section
+          titles.
+
+       M. Delete any section Entitled "Endorsements".  Such a section
+          may not be included in the Modified Version.
+
+       N. Do not retitle any existing section to be Entitled
+          "Endorsements" or to conflict in title with any Invariant
+          Section.
+
+       O. Preserve any Warranty Disclaimers.
+
+     If the Modified Version includes new front-matter sections or
+     appendices that qualify as Secondary Sections and contain no
+     material copied from the Document, you may at your option
+     designate some or all of these sections as invariant.  To do this,
+     add their titles to the list of Invariant Sections in the Modified
+     Version's license notice.  These titles must be distinct from any
+     other section titles.
+
+     You may add a section Entitled "Endorsements", provided it contains
+     nothing but endorsements of your Modified Version by various
+     parties--for example, statements of peer review or that the text
+     has been approved by an organization as the authoritative
+     definition of a standard.
+
+     You may add a passage of up to five words as a Front-Cover Text,
+     and a passage of up to 25 words as a Back-Cover Text, to the end
+     of the list of Cover Texts in the Modified Version.  Only one
+     passage of Front-Cover Text and one of Back-Cover Text may be
+     added by (or through arrangements made by) any one entity.  If the
+     Document already includes a cover text for the same cover,
+     previously added by you or by arrangement made by the same entity
+     you are acting on behalf of, you may not add another; but you may
+     replace the old one, on explicit permission from the previous
+     publisher that added the old one.
+
+     The author(s) and publisher(s) of the Document do not by this
+     License give permission to use their names for publicity for or to
+     assert or imply endorsement of any Modified Version.
+
+  5. COMBINING DOCUMENTS
+
+     You may combine the Document with other documents released under
+     this License, under the terms defined in section 4 above for
+     modified versions, provided that you include in the combination
+     all of the Invariant Sections of all of the original documents,
+     unmodified, and list them all as Invariant Sections of your
+     combined work in its license notice, and that you preserve all
+     their Warranty Disclaimers.
+
+     The combined work need only contain one copy of this License, and
+     multiple identical Invariant Sections may be replaced with a single
+     copy.  If there are multiple Invariant Sections with the same name
+     but different contents, make the title of each such section unique
+     by adding at the end of it, in parentheses, the name of the
+     original author or publisher of that section if known, or else a
+     unique number.  Make the same adjustment to the section titles in
+     the list of Invariant Sections in the license notice of the
+     combined work.
+
+     In the combination, you must combine any sections Entitled
+     "History" in the various original documents, forming one section
+     Entitled "History"; likewise combine any sections Entitled
+     "Acknowledgements", and any sections Entitled "Dedications".  You
+     must delete all sections Entitled "Endorsements."
+
+  6. COLLECTIONS OF DOCUMENTS
+
+     You may make a collection consisting of the Document and other
+     documents released under this License, and replace the individual
+     copies of this License in the various documents with a single copy
+     that is included in the collection, provided that you follow the
+     rules of this License for verbatim copying of each of the
+     documents in all other respects.
+
+     You may extract a single document from such a collection, and
+     distribute it individually under this License, provided you insert
+     a copy of this License into the extracted document, and follow
+     this License in all other respects regarding verbatim copying of
+     that document.
+
+  7. AGGREGATION WITH INDEPENDENT WORKS
+
+     A compilation of the Document or its derivatives with other
+     separate and independent documents or works, in or on a volume of
+     a storage or distribution medium, is called an "aggregate" if the
+     copyright resulting from the compilation is not used to limit the
+     legal rights of the compilation's users beyond what the individual
+     works permit.  When the Document is included in an aggregate, this
+     License does not apply to the other works in the aggregate which
+     are not themselves derivative works of the Document.
+
+     If the Cover Text requirement of section 3 is applicable to these
+     copies of the Document, then if the Document is less than one half
+     of the entire aggregate, the Document's Cover Texts may be placed
+     on covers that bracket the Document within the aggregate, or the
+     electronic equivalent of covers if the Document is in electronic
+     form.  Otherwise they must appear on printed covers that bracket
+     the whole aggregate.
+
+  8. TRANSLATION
+
+     Translation is considered a kind of modification, so you may
+     distribute translations of the Document under the terms of section
+     4.  Replacing Invariant Sections with translations requires special
+     permission from their copyright holders, but you may include
+     translations of some or all Invariant Sections in addition to the
+     original versions of these Invariant Sections.  You may include a
+     translation of this License, and all the license notices in the
+     Document, and any Warranty Disclaimers, provided that you also
+     include the original English version of this License and the
+     original versions of those notices and disclaimers.  In case of a
+     disagreement between the translation and the original version of
+     this License or a notice or disclaimer, the original version will
+     prevail.
+
+     If a section in the Document is Entitled "Acknowledgements",
+     "Dedications", or "History", the requirement (section 4) to
+     Preserve its Title (section 1) will typically require changing the
+     actual title.
+
+  9. TERMINATION
+
+     You may not copy, modify, sublicense, or distribute the Document
+     except as expressly provided for under this License.  Any other
+     attempt to copy, modify, sublicense or distribute the Document is
+     void, and will automatically terminate your rights under this
+     License.  However, parties who have received copies, or rights,
+     from you under this License will not have their licenses
+     terminated so long as such parties remain in full compliance.
+
+ 10. FUTURE REVISIONS OF THIS LICENSE
+
+     The Free Software Foundation may publish new, revised versions of
+     the GNU Free Documentation License from time to time.  Such new
+     versions will be similar in spirit to the present version, but may
+     differ in detail to address new problems or concerns.  See
+     `http://www.gnu.org/copyleft/'.
+
+     Each version of the License is given a distinguishing version
+     number.  If the Document specifies that a particular numbered
+     version of this License "or any later version" applies to it, you
+     have the option of following the terms and conditions either of
+     that specified version or of any later version that has been
+     published (not as a draft) by the Free Software Foundation.  If
+     the Document does not specify a version number of this License,
+     you may choose any version ever published (not as a draft) by the
+     Free Software Foundation.
+
+A.1 ADDENDUM: How to Use This License For Your Documents
+========================================================
+
+To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and license
+notices just after the title page:
+
+       Copyright (C)  YEAR  YOUR NAME.
+       Permission is granted to copy, distribute and/or modify this document
+       under the terms of the GNU Free Documentation License, Version 1.2
+       or any later version published by the Free Software Foundation;
+       with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
+       Texts.  A copy of the license is included in the section entitled ``GNU
+       Free Documentation License''.
+
+   If you have Invariant Sections, Front-Cover Texts and Back-Cover
+Texts, replace the "with...Texts." line with this:
+
+         with the Invariant Sections being LIST THEIR TITLES, with
+         the Front-Cover Texts being LIST, and with the Back-Cover Texts
+         being LIST.
+
+   If you have Invariant Sections without Cover Texts, or some other
+combination of the three, merge those two alternatives to suit the
+situation.
+
+   If your document contains nontrivial examples of program code, we
+recommend releasing these examples in parallel under your choice of
+free software license, such as the GNU General Public License, to
+permit their use in free software.

+@chapter Introduction to MPFR
+
+
+MPFR is a portable library written in C for arbitrary precision arithmetic
+on floating-point numbers. It is based on the GNU MP library.
+It aims to provide a class of floating-point numbers with
+precise semantics. The main characteristics of MPFR, which make it differ
+from most arbitrary precision floating-point software tools, are:
+
+@itemize @bullet
+@item the MPFR code is portable, i.e., the result of any operation
+does not depend on the machine word size
+@code{mp_bits_per_limb} (64 on most current processors);
+@item the precision in bits can be set @emph{exactly} to any valid value
+for each variable (including very small precision);
+@item MPFR provides the four rounding modes from the IEEE 754-1985
+standard, plus away-from-zero, as well as for basic operations as for other
+mathematical functions.
+@end itemize
+
+In particular, with a precision of 53 bits, MPFR is able to
+exactly reproduce all computations with double-precision machine
+floating-point numbers (e.g., @code{double} type in C, with a C
+implementation that rigorously follows Annex F of the ISO C99 standard
+and @code{FP_CONTRACT} pragma set to @code{OFF}) on the four arithmetic
+operations and the square root, except the default exponent range is much
+wider and subnormal numbers are not implemented (but can be emulated).
+
+This version of MPFR is released under the GNU Lesser General Public
+License, version 3 or any later version.
+It is permitted to link MPFR to most non-free programs, as long as when
+distributing them the MPFR source code and a means to re-link with a
+modified MPFR library is provided.
+
+@section How to Use This Manual
+
+Everyone should read @ref{MPFR Basics}.  If you need to install the library
+yourself, you need to read @ref{Installing MPFR}, too.
+To use the library you will need to refer to @ref{MPFR Interface}.
+
+The rest of the manual can be used for later reference, although it is
+probably a good idea to glance through it.

+@chapter Installing MPFR
+@cindex Installation
+
+The MPFR library is already installed on some GNU/Linux distributions,
+but the development files necessary to the compilation such as
+@file{mpfr.h} are not always present. To check that MPFR is fully
+installed on your computer, you can check the presence of the file
+@file{mpfr.h} in @file{/usr/include}, or try to compile a small program
+having @code{#include <mpfr.h>} (since @file{mpfr.h} may be installed
+somewhere else). For instance, you can try to compile:
+
+@example
+#include <stdio.h>
+#include <mpfr.h>
+int main (void)
+@{
+  printf ("MPFR library: %-12s\nMPFR header:  %s (based on %d.%d.%d)\n",
+          mpfr_get_version (), MPFR_VERSION_STRING, MPFR_VERSION_MAJOR,
+          MPFR_VERSION_MINOR, MPFR_VERSION_PATCHLEVEL);
+  return 0;
+@}
+@end example
+
+@noindent
+with
+
+@example
+cc -o version version.c -lmpfr -lgmp
+@end example
+
+@noindent
+and if you get errors whose first line looks like
+
+@example
+version.c:2:19: error: mpfr.h: No such file or directory
+@end example
+
+@noindent
+then MPFR is probably not installed. Running this program will give you
+the MPFR version.
+
+If MPFR is not installed on your computer, or if you want to install a
+different version, please follow the steps below.
+
+@section How to Install
+
+Here are the steps needed to install the library on Unix systems
+(more details are provided in the @file{INSTALL} file):
+
+@enumerate
+@item
+To build MPFR, you first have to install GNU MP
+(version 4.1 or higher) on your computer.
+You need a C compiler, preferably GCC, but any reasonable compiler should
+work.  And you need the standard Unix @samp{make} command, plus some other
+standard Unix utility commands.
+
+Then, in the MPFR build directory, type the following commands.
+
+@item
+@samp{./configure}
+
+This will prepare the build and setup the options according to your system.
+You can give options to specify the install directories (instead of
+the default @file{/usr/local}), threading support, and so on. See
+the @file{INSTALL} file and/or the output of @samp{./configure --help}
+for more information, in particular if you get error messages.
+
+@item
+@samp{make}
+
+This will compile MPFR, and create a library archive file @file{libmpfr.a}.
+On most platforms, a dynamic library will be produced too.
+@item
+@samp{make check}
+
+This will make sure MPFR was built correctly.
+If you get error messages, please report this to the MPFR mailing-list
+@samp{mpfr@@inria.fr}.  (@xref{Reporting Bugs}, for
+information on what to include in useful bug reports.)
+
+@item
+@samp{make install}
+
+This will copy the files @file{mpfr.h} and @file{mpf2mpfr.h} to the directory
+@file{/usr/local/include}, the library files (@file{libmpfr.a} and possibly
+others) to the directory @file{/usr/local/lib}, the file @file{mpfr.info}
+to the directory @file{/usr/local/share/info}, and some other documentation
+files to the directory @file{/usr/local/share/doc/mpfr} (or if you passed the
+@samp{--prefix} option to @file{configure}, using the prefix directory given
+as argument to @samp{--prefix} instead of @file{/usr/local}).
+@end enumerate
+
+@section Other `make' Targets
+
+There are some other useful make targets:
+
+@itemize @bullet
+@item
+@samp{mpfr.info} or @samp{info}
+
+Create or update an info version of the manual, in @file{mpfr.info}.
+
+This file is already provided in the MPFR archives.
+
+@item
+@samp{mpfr.pdf} or @samp{pdf}
+
+Create a PDF version of the manual, in @file{mpfr.pdf}.
+
+@item
+@samp{mpfr.dvi} or @samp{dvi}
+
+Create a DVI version of the manual, in @file{mpfr.dvi}.
+
+@item
+@samp{mpfr.ps} or @samp{ps}
+
+Create a Postscript version of the manual, in @file{mpfr.ps}.
+
+@item
+@samp{mpfr.html} or @samp{html}
+
+Create a HTML version of the manual, in several pages in the directory
+@file{doc/mpfr.html}; if you want only one output HTML file, then type
+@samp{makeinfo --html --no-split mpfr.texi} from the @samp{doc} directory
+instead.
+
+@item
+@samp{clean}
+
+Delete all object files and archive files, but not the configuration files.
+
+@item
+@samp{distclean}
+
+Delete all generated files not included in the distribution.
+
+@item
+@samp{uninstall}
+
+Delete all files copied by @samp{make install}.
+@end itemize
+
+
+@section Build Problems
+
+In case of problem, please read the @file{INSTALL} file carefully
+before reporting a bug, in particular section ``In case of problem''.
+Some problems are due to bad configuration on the user side (not
+specific to MPFR). Problems are also mentioned in the FAQ
+@url{http://www.mpfr.org/faq.html}.
+
+@comment Warning! Do not split "MPFR ... @url{...}" across several lines
+@comment as this needs to be updated with update-version.
+Please report problems to the MPFR mailing-list @samp{mpfr@@inria.fr}.
+@xref{Reporting Bugs}.
+Some bug fixes are available on the
+MPFR 3.1.2 web page @url{http://www.mpfr.org/mpfr-3.1.2/}.
+
+@section Getting the Latest Version of MPFR
+
+The latest version of MPFR is available from

+
+@comment Warning! Do not split "MPFR ... @url{...}" across several lines
+@comment as this needs to be updated with update-version.
+If you think you have found a bug in the MPFR library, first have a look
+on the MPFR 3.1.2 web page @url{http://www.mpfr.org/mpfr-3.1.2/} and the
+FAQ @url{http://www.mpfr.org/faq.html}:
+perhaps this bug is already known, in which case you may find there
+a workaround for it.
+You might also look in the archives of the MPFR mailing-list:
+@url{https://sympa.inria.fr/sympa/arc/mpfr}.
+Otherwise, please investigate and report it.
+We have made this library available to you, and it is not to ask too
+much from you, to ask you to report the bugs that you find.
+
+There are a few things you should think about when you put your bug report
+together.
+
+You have to send us a test case that makes it possible for us to reproduce the
+bug, i.e., a small self-content program, using no other library than MPFR.
+Include instructions on how to run the test case.
+
+You also have to explain what is wrong; if you get a crash, or if the results
+you get are incorrect and in that case, in what way.
+
+Please include compiler version information in your bug report. This can
+be extracted using @samp{cc -V} on some machines, or, if you're using GCC,
+@samp{gcc -v}. Also, include the output from @samp{uname -a} and the MPFR
+version (the GMP version may be useful too).
+If you get a failure while running @samp{make} or @samp{make check}, please
+include the @samp{config.log} file in your bug report.
+
+If your bug report is good, we will do our best to help you to get a corrected
+version of the library; if the bug report is poor, we will not do anything
+about it (aside of chiding you to send better bug reports).
+
+Send your bug report to the MPFR mailing-list @samp{mpfr@@inria.fr}.
+
+If you think something in this manual is unclear, or downright incorrect, or if
+the language needs to be improved, please send a note to the same address.

+
+@cindex @file{mpfr.h}
+All declarations needed to use MPFR are collected in the include file
+@file{mpfr.h}.  It is designed to work with both C and C++ compilers.
+You should include that file in any program using the MPFR library:
+
+@example
+#include <mpfr.h>
+@end example
+
+@cindex @code{stdio.h}
+Note however that prototypes for MPFR functions with @code{FILE *} parameters
+are provided only if @code{<stdio.h>} is included too (before @file{mpfr.h}):
+
+@example
+#include <stdio.h>
+#include <mpfr.h>
+@end example
+
+@cindex @code{stdarg.h}
+Likewise @code{<stdarg.h>} (or @code{<varargs.h>}) is required for prototypes
+with @code{va_list} parameters, such as @code{mpfr_vprintf}.
+
+@cindex @code{stdint.h}
+@cindex @code{inttypes.h}
+@cindex @code{intmax_t}
+@cindex @code{uintmax_t}
+And for any functions using @code{intmax_t}, you must include
+@code{<stdint.h>} or @code{<inttypes.h>} before @file{mpfr.h}, to
+allow @file{mpfr.h} to define prototypes for these functions. Moreover,
+users of C++ compilers under some platforms may need to define
+@code{MPFR_USE_INTMAX_T} (and should do it for portability) before
+@file{mpfr.h} has been included; of course, it is possible to do that
+on the command line, e.g., with @code{-DMPFR_USE_INTMAX_T}.
+
+Note: If @file{mpfr.h} and/or @file{gmp.h} (used by @file{mpfr.h})
+are included several times (possibly from another header file),
+@code{<stdio.h>} and/or @code{<stdarg.h>} (or @code{<varargs.h>})
+should be included @strong{before the first inclusion} of
+@file{mpfr.h} or @file{gmp.h}.  Alternatively, you can define
+@code{MPFR_USE_FILE} (for MPFR I/O functions) and/or
+@code{MPFR_USE_VA_LIST} (for MPFR functions with @code{va_list}
+parameters) anywhere before the last inclusion of @file{mpfr.h}.
+As a consequence, if your file is a public header that includes
+@file{mpfr.h}, you need to use the latter method.
+
+When calling a MPFR macro, it is not allowed to have previously defined
+a macro with the same name as some keywords (currently @code{do},
+@code{while} and @code{sizeof}).
+
+You can avoid the use of MPFR macros encapsulating functions by defining
+the @code{MPFR_USE_NO_MACRO} macro before @file{mpfr.h} is included.  In
+general this should not be necessary, but this can be useful when debugging
+user code: with some macros, the compiler may emit spurious warnings with
+some warning options, and macros can prevent some prototype checking.
+
+@cindex Libraries
+@cindex Linking
+@cindex @code{libmpfr}
+All programs using MPFR must link against both @file{libmpfr} and
+@file{libgmp} libraries.  On a typical Unix-like system this can be
+done with @samp{-lmpfr -lgmp} (in that order), for example:
+
+@example
+gcc myprogram.c -lmpfr -lgmp
+@end example
+
+@cindex Libtool
+MPFR is built using Libtool and an application can use that to link if
+desired, @MPFRpxreftop{libtool.info, GNU Libtool}
+@c Note: the .info extension has been added to avoid the following bug:
+@c   http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=484740
+@c which occurs when reading the info file from the build directory:
+@c   info ./mpfr    or    info -f ./mpfr.info
+@c Due to a poor design, the "info" utility will not find the correct
+@c libtool info file if the .info extension is not provided, because of
+@c the "libtool" script in MPFR's directory!
+
+If MPFR has been installed to a non-standard location, then it may be
+necessary to set up environment variables such as @samp{C_INCLUDE_PATH}
+and @samp{LIBRARY_PATH}, or use @samp{-I} and @samp{-L} compiler options,
+in order to point to the right directories. For a shared library, it may
+also be necessary to set up some sort of run-time library path (e.g.,
+@samp{LD_LIBRARY_PATH}) on some systems. Please read the @file{INSTALL}
+file for additional information.

+@section Nomenclature and Types
+
+@cindex Floating-point number
+@tindex @code{mpfr_t}
+@noindent
+A @dfn{floating-point number}, or @dfn{float} for short, is an arbitrary
+precision significand (also called mantissa) with a limited precision
+exponent. The C data type
+for such objects is @code{mpfr_t} (internally defined as a one-element
+array of a structure, and @code{mpfr_ptr} is the C data type representing
+a pointer to this structure). A floating-point number can have
+three special values: Not-a-Number (NaN) or plus or minus Infinity. NaN
+represents an uninitialized object, the result of an invalid operation
+(like 0 divided by 0), or a value that cannot be determined (like
++Infinity minus +Infinity). Moreover, like in the IEEE 754 standard,
+zero is signed, i.e., there are both +0 and @minus{}0; the behavior
+is the same as in the IEEE 754 standard and it is generalized to
+the other functions supported by MPFR. Unless documented otherwise,
+the sign bit of a NaN is unspecified.
+@c VL: re-added how mpfr_t is defined, due to some questions from users
+@c in the past (the fact that the result was returned in an argument
+@c seemed strange); also, mpfr_ptr needs to be defined here, as it is
+@c used in the API.
+
+@cindex Precision
+@tindex @code{mpfr_prec_t}
+@noindent
+The @dfn{precision} is the number of bits used to represent the significand
+of a floating-point number;
+the corresponding C data type is @code{mpfr_prec_t}.
+The precision can be any integer between @code{MPFR_PREC_MIN} and
+@code{MPFR_PREC_MAX}. In the current implementation, @code{MPFR_PREC_MIN}
+is equal to 2.
+
+Warning! MPFR needs to increase the precision internally, in order to
+provide accurate results (and in particular, correct rounding). Do not
+attempt to set the precision to any value near @code{MPFR_PREC_MAX},
+otherwise MPFR will abort due to an assertion failure. Moreover, you
+may reach some memory limit on your platform, in which case the program
+may abort, crash or have undefined behavior (depending on your C
+implementation).
+
+@cindex Rounding Modes
+@tindex @code{mpfr_rnd_t}
+@noindent
+The @dfn{rounding mode} specifies the way to round the result of a
+floating-point operation, in case the exact result can not be represented
+exactly in the destination significand;
+the corresponding C data type is @code{mpfr_rnd_t}.
+
+@node MPFR Variable Conventions, Rounding Modes, Nomenclature and Types, MPFR Basics
+@comment  node-name,  next,  previous,  up
+@section MPFR Variable Conventions
+
+Before you can assign to an MPFR variable, you need to initialize it by calling
+one of the special initialization functions.  When you're done with a
+variable, you need to clear it out, using one of the functions for that
+purpose.
+A variable should only be initialized once, or at least cleared out between
+each initialization.  After a variable has been initialized, it may be
+assigned to any number of times.
+For efficiency reasons, avoid to initialize and clear out a variable in loops.
+Instead, initialize it before entering the loop, and clear it out after the
+loop has exited.
+You do not need to be concerned about allocating additional space for MPFR
+variables, since any variable has a significand of fixed size.
+Hence unless you change its precision, or clear and reinitialize it,
+a floating-point variable will have the same allocated space during all its
+life.
+
+As a general rule, all MPFR functions expect output arguments before input
+arguments.  This notation is based on an analogy with the assignment operator.
+MPFR allows you to use the same variable for both input and output in the same
+expression.  For example, the main function for floating-point multiplication,
+@code{mpfr_mul}, can be used like this: @code{mpfr_mul (x, x, x, rnd)}.
+This
+computes the square of @var{x} with rounding mode @code{rnd}
+and puts the result back in @var{x}.
+
+@node Rounding Modes, Floating-Point Values on Special Numbers, MPFR Variable Conventions, MPFR Basics
+@comment  node-name,  next,  previous,  up
+@section Rounding Modes
+
+The following five rounding modes are supported:
+
+@itemize @bullet
+@item @code{MPFR_RNDN}: round to nearest (roundTiesToEven in IEEE 754-2008),
+@item @code{MPFR_RNDZ}: round toward zero (roundTowardZero in IEEE 754-2008),
+@item @code{MPFR_RNDU}: round toward plus infinity (roundTowardPositive in IEEE 754-2008),
+@item @code{MPFR_RNDD}: round toward minus infinity (roundTowardNegative in IEEE 754-2008),
+@item @code{MPFR_RNDA}: round away from zero.
+@end itemize
+
+The @samp{round to nearest} mode works as in the IEEE 754 standard: in
+case the number to be rounded lies exactly in the middle of two representable
+numbers, it is rounded to the one with the least significant bit set to zero.
+For example, the number 2.5, which is represented by (10.1) in binary, is
+rounded to (10.0)=2 with a precision of two bits, and not to (11.0)=3.
+This rule avoids the @dfn{drift} phenomenon mentioned by Knuth in volume 2
+of The Art of Computer Programming (Section 4.2.2).
+
+@anchor{ternary value}@cindex Ternary value
+Most MPFR functions take as first argument the destination variable, as
+second and following arguments the input variables, as last argument a
+rounding mode, and have a return value of type @code{int}, called the
+@dfn{ternary value}. The value stored in the destination variable is
+correctly rounded, i.e., MPFR behaves as if it computed the result with
+an infinite precision, then rounded it to the precision of this variable.
+The input variables are regarded as exact (in particular, their precision
+does not affect the result).
+
+As a consequence, in case of a non-zero real rounded result, the error
+on the result is less or equal to 1/2 ulp (unit in the last place) of
+that result in the rounding to nearest mode, and less than 1 ulp of that
+result in the directed rounding modes (a ulp is the weight of the least
+significant represented bit of the result after rounding).
+@c Since subnormals are not supported, we must take into account the ulp of
+@c the rounded result, not the one of the exact result, for full generality.
+
+Unless documented otherwise, functions returning an @code{int} return
+a ternary value.
+If the ternary value is zero, it means that the value stored in the
+destination variable is the exact result of the corresponding mathematical
+function. If the ternary value is positive (resp.@: negative), it means
+the value stored in the destination variable is greater (resp.@: lower)
+than the exact result. For example with the @code{MPFR_RNDU} rounding mode,
+the ternary value is usually positive, except when the result is exact, in
+which case it is zero. In the case of an infinite result, it is considered
+as inexact when it was obtained by overflow, and exact otherwise. A NaN
+result (Not-a-Number) always corresponds to an exact return value.
+The opposite of a returned ternary value is guaranteed to be representable
+in an @code{int}.
+
+Unless documented otherwise, functions returning as result the value @code{1}
+(or any other value specified in this manual)
+for special cases (like @code{acos(0)}) yield an overflow or

+@section Floating-Point Values on Special Numbers
+
+This section specifies the floating-point values (of type @code{mpfr_t})
+returned by MPFR functions (where by ``returned'' we mean here the modified
+value of the destination object, which should not be mixed with the ternary
+return value of type @code{int} of those functions).
+For functions returning several values (like
+@code{mpfr_sin_cos}), the rules apply to each result separately.
+
+Functions can have one or several input arguments. An input point is
+a mapping from these input arguments to the set of the MPFR numbers.
+When none of its components are NaN, an input point can also be seen
+as a tuple in the extended real numbers (the set of the real numbers
+with both infinities).
+
+When the input point is in the domain of the mathematical function, the
+result is rounded as described in Section ``Rounding Modes'' (but see
+below for the specification of the sign of an exact zero). Otherwise
+the general rules from this section apply unless stated otherwise in
+the description of the MPFR function (@ref{MPFR Interface}).
+
+When the input point is not in the domain of the mathematical function
+but is in its closure in the extended real numbers and the function can
+be extended by continuity, the result is the obtained limit.
+Examples: @code{mpfr_hypot} on (+Inf,0) gives +Inf. But @code{mpfr_pow}
+cannot be defined on (1,+Inf) using this rule, as one can find
+sequences (@m{x_n,@var{x}_@var{n}},@m{y_n,@var{y}_@var{n}}) such that
+@m{x_n,@var{x}_@var{n}} goes to 1, @m{y_n,@var{y}_@var{n}} goes to +Inf
+and @m{(x_n)^{y_n},@var{x}_@var{n} to the @var{y}_@var{n}} goes to any
+positive value when @var{n} goes to the infinity.
+
+When the input point is in the closure of the domain of the mathematical
+function and an input argument is +0 (resp.@: @minus{}0), one considers
+the limit when the corresponding argument approaches 0 from above
+(resp.@: below). If the limit is not defined (e.g., @code{mpfr_log} on
+@minus{}0), the behavior is specified in the description of the MPFR function.
+
+When the result is equal to 0, its sign is determined by considering the
+limit as if the input point were not in the domain: If one approaches 0
+from above (resp.@: below), the result is +0 (resp.@: @minus{}0);
+for example, @code{mpfr_sin} on +0 gives +0.
+In the other cases, the sign is specified in the description of the MPFR
+function; for example @code{mpfr_max} on @minus{}0 and +0 gives +0.
+
+When the input point is not in the closure of the domain of the function,
+the result is NaN. Example: @code{mpfr_sqrt} on @minus{}17 gives NaN.
+
+When an input argument is NaN, the result is NaN, possibly except when
+a partial function is constant on the finite floating-point numbers;
+such a case is always explicitly specified in @ref{MPFR Interface}.
+@c Said otherwise, if such a case is not specified, this is a bug, thus
+@c we may change the returned value after documenting it without having
+@c to change the libtool interface number (this would have more drawbacks
+@c that advantages in practice), like for any bug fix.
+Example: @code{mpfr_hypot} on (NaN,0) gives NaN, but @code{mpfr_hypot}
+on (NaN,+Inf) gives +Inf (as specified in @ref{Special Functions}),
+since for any finite input @var{x}, @code{mpfr_hypot} on (@var{x},+Inf)
+gives +Inf.

+@comment  node-name,  next,  previous,  up
+@section Exceptions
+
+MPFR supports 6 exception types:
+
+@itemize @bullet
+
+@item Underflow:
+An underflow occurs when the exact result of a function is a non-zero
+real number and the result obtained after the rounding, assuming an
+unbounded exponent range (for the rounding), has an exponent smaller
+than the minimum value of the current exponent range. (In the round-to-nearest
+mode, the halfway case is rounded toward zero.)
+
+Note: This is not the single possible definition of the underflow. MPFR chooses
+to consider the underflow @emph{after} rounding. The underflow before rounding
+can also be defined. For instance, consider a function that has the
+exact result @m{7 \times 2^{e-4}, 7 multiplied by two to the power
+@var{e}@minus{}4}, where @var{e} is the smallest exponent (for a
+significand between 1/2 and 1),
+with a 2-bit target precision and rounding toward plus infinity.
+The exact result has the exponent @var{e}@minus{}1. With the underflow
+before rounding, such a function call would yield an underflow, as
+@var{e}@minus{}1 is outside the current exponent range. However, MPFR
+first considers the rounded result assuming an unbounded exponent range.
+The exact result cannot be represented exactly in precision 2, and here,
+it is rounded to @m{0.5 @times 2^e, 0.5 times 2 to @var{e}}, which is
+representable in the current exponent range. As a consequence, this will
+not yield an underflow in MPFR.
+
+@item Overflow:
+An overflow occurs when the exact result of a function is a non-zero
+real number and the result obtained after the rounding, assuming an
+unbounded exponent range (for the rounding), has an exponent larger
+than the maximum value of the current exponent range. In the round-to-nearest
+mode, the result is infinite.
+Note: unlike the underflow case, there is only one possible definition of
+overflow here.
+
+@item Divide-by-zero:
+An exact infinite result is obtained from finite inputs.
+
+@item NaN:
+A NaN exception occurs when the result of a function is NaN.
+@c NaN is defined above. So, we don't say anything more.
+
+@item Inexact:
+An inexact exception occurs when the result of a function cannot be
+represented exactly and must be rounded.
+
+@item Range error:
+A range exception occurs when a function that does not return a MPFR
+number (such as comparisons and conversions to an integer) has an
+invalid result (e.g., an argument is NaN in @code{mpfr_cmp}, or a
+conversion to an integer cannot be represented in the target type).
+
+@end itemize
+
+MPFR has a global flag for each exception, which can be cleared, set
+or tested by functions described in @ref{Exception Related Functions}.
+
+Differences with the ISO C99 standard:
+
+@itemize @bullet
+
+@item In C, only quiet NaNs are specified, and a NaN propagation does not
+raise an invalid exception. Unless explicitly stated otherwise, MPFR sets
+the NaN flag whenever a NaN is generated, even when a NaN is propagated
+(e.g., in NaN + NaN), as if all NaNs were signaling.
+
+@item An invalid exception in C corresponds to either a NaN exception or
+a range error in MPFR.
+
+@end itemize
+
+@node Memory Handling, , Exceptions, MPFR Basics
+@comment  node-name,  next,  previous,  up
+@section Memory Handling
+
+MPFR functions may create caches, e.g., when computing constants such
+as @m{\pi,Pi}, either because the user has called a function like
+@code{mpfr_const_pi} directly or because such a function was called
+internally by the MPFR library itself to compute some other function.
+
+At any time, the user can free the various caches with
+@code{mpfr_free_cache}. It is strongly advised to do that before
+terminating a thread, or before exiting when using tools like
+@samp{valgrind} (to avoid memory leaks being reported).
+
+MPFR internal data such as flags, the exponent range, the default
+precision and rounding mode, and caches (i.e., data that are not
+accessed via parameters) are either global (if MPFR has not been
+compiled as thread safe) or per-thread (thread local storage, TLS).
+The initial values of TLS data after a thread is created entirely
+depend on the compiler and thread implementation (MPFR simply does
+a conventional variable initialization, the variables being declared
+with an implementation-defined TLS specifier).
+@c References to TLS specification or documentation can be given here.
+@c Concerning some thread implementations under Unix, POSIX specifies
+@c the thread interface only; TLS variables (with the __thread specifier)
+@c is just a GCC extension. There is currently no clear documentation
+@c about TLS variable initialization.

+@chapter MPFR Interface
+@cindex Floating-point functions
+@cindex Float functions
+
+The floating-point functions expect arguments of type @code{mpfr_t}.
+
+The MPFR floating-point functions have an interface that is similar to the
+GNU MP
+functions.  The function prefix for floating-point operations is @code{mpfr_}.
+
+The user has
+to specify the precision of each variable.  A computation that assigns a
+variable will take place with the precision of the assigned variable; the
+cost of that computation should not depend on the
+precision of variables used as input (on average).
+
+@cindex Precision
+The semantics of a calculation in MPFR is specified as follows: Compute the
+requested operation exactly (with ``infinite accuracy''), and round the result
+to the precision of the destination variable, with the given rounding mode.
+The MPFR floating-point functions are intended to be a smooth extension
+of the IEEE 754 arithmetic. The results obtained on a given computer are
+identical to those obtained on a computer with a different word size,
+or with a different compiler or operating system.
+
+@cindex Accuracy
+MPFR @emph{does not keep track} of the accuracy of a computation. This is left
+to the user or to a higher layer (for example the MPFI library for interval
+arithmetic).
+As a consequence, if two variables are used to store
+only a few significant bits, and their product is stored in a variable with large
+precision, then MPFR will still compute the result with full precision.
+
+The value of the standard C macro @code{errno} may be set to non-zero by
+any MPFR function or macro, whether or not there is an error.

+@cindex Initialization functions
+@section Initialization Functions
+
+An @code{mpfr_t} object must be initialized before storing the first value in
+it.  The functions @code{mpfr_init} and @code{mpfr_init2} are used for that
+purpose.
+
+@deftypefun void mpfr_init2 (mpfr_t @var{x}, mpfr_prec_t @var{prec})
+Initialize @var{x}, set its precision to be @strong{exactly}
+@var{prec} bits and its value to NaN. (Warning: the corresponding
+MPF function initializes to zero instead.)
+
+Normally, a variable should be initialized once only or at
+least be cleared, using @code{mpfr_clear}, between initializations.
+To change the precision of a variable which has already been initialized,
+use @code{mpfr_set_prec}.
+The precision @var{prec} must be an integer between @code{MPFR_PREC_MIN} and
+@code{MPFR_PREC_MAX} (otherwise the behavior is undefined).
+@end deftypefun
+
+@deftypefun void mpfr_inits2 (mpfr_prec_t @var{prec}, mpfr_t @var{x}, ...)
+Initialize all the @code{mpfr_t} variables of the given variable
+argument @code{va_list}, set their precision to be @strong{exactly}
+@var{prec} bits and their value to NaN.
+See @code{mpfr_init2} for more details.
+The @code{va_list} is assumed to be composed only of type @code{mpfr_t}
+(or equivalently @code{mpfr_ptr}).
+It begins from @var{x}, and ends when it encounters a null pointer (whose
+type must also be @code{mpfr_ptr}).
+@end deftypefun
+
+@deftypefun void mpfr_clear (mpfr_t @var{x})
+Free the space occupied by the significand of
+@var{x}.  Make sure to call this function for all
+@code{mpfr_t} variables when you are done with them.
+@end deftypefun
+
+@deftypefun void mpfr_clears (mpfr_t @var{x}, ...)
+Free the space occupied by all the @code{mpfr_t} variables of the given
+@code{va_list}. See @code{mpfr_clear} for more details.
+The @code{va_list} is assumed to be composed only of type @code{mpfr_t}
+(or equivalently @code{mpfr_ptr}).
+It begins from @var{x}, and ends when it encounters a null pointer (whose
+type must also be @code{mpfr_ptr}).
+@end deftypefun
+
+Here is an example of how to use multiple initialization functions
+(since @code{NULL} is not necessarily defined in this context, we use
+@code{(mpfr_ptr) 0} instead, but @code{(mpfr_ptr) NULL} is also correct).
+
+@example
+@{
+  mpfr_t x, y, z, t;
+  mpfr_inits2 (256, x, y, z, t, (mpfr_ptr) 0);
+  @dots{}
+  mpfr_clears (x, y, z, t, (mpfr_ptr) 0);
+@}
+@end example
+
+@deftypefun void mpfr_init (mpfr_t @var{x})
+Initialize @var{x}, set its precision to the default precision,
+and set its value to NaN.
+The default precision can be changed by a call to @code{mpfr_set_default_prec}.
+
+Warning! In a given program, some other libraries might change the default
+precision and not restore it. Thus it is safer to use @code{mpfr_init2}.
+@end deftypefun
+
+@deftypefun void mpfr_inits (mpfr_t @var{x}, ...)
+Initialize all the @code{mpfr_t} variables of the given @code{va_list},
+set their precision to the default precision and their value to NaN.
+See @code{mpfr_init} for more details.
+The @code{va_list} is assumed to be composed only of type @code{mpfr_t}
+(or equivalently @code{mpfr_ptr}).
+It begins from @var{x}, and ends when it encounters a null pointer (whose
+type must also be @code{mpfr_ptr}).

+@end deftypefun
+
+@defmac MPFR_DECL_INIT (@var{name}, @var{prec})
+This macro declares @var{name} as an automatic variable of type @code{mpfr_t},
+initializes it and sets its precision to be @strong{exactly} @var{prec} bits
+and its value to NaN. @var{name} must be a valid identifier.
+You must use this macro in the declaration section.
+This macro is much faster than using @code{mpfr_init2} but has some
+drawbacks:
+
+@itemize @bullet
+@item You @strong{must not} call @code{mpfr_clear} with variables
+created with this macro (the storage is allocated at the point of declaration
+and deallocated when the brace-level is exited).
+@item You @strong{cannot} change their precision.
+@item You @strong{should not} create variables with huge precision with this
+macro.
+@item Your compiler must support @samp{Non-Constant Initializers} (standard
+in C++ and ISO C99) and @samp{Token Pasting}
+(standard in ISO C89). If @var{prec} is not a constant expression, your
+compiler must support @samp{variable-length automatic arrays} (standard
+in ISO C99). GCC 2.95.3 and above supports all these features.
+If you compile your program with GCC in C89 mode and with @samp{-pedantic},
+you may want to define the @code{MPFR_USE_EXTENSION} macro to avoid warnings
+due to the @code{MPFR_DECL_INIT} implementation.
+@end itemize
+@end defmac
+
+@deftypefun void mpfr_set_default_prec (mpfr_prec_t @var{prec})
+Set the default precision to be @strong{exactly} @var{prec} bits, where
+@var{prec} can be any integer between @code{MPFR_PREC_MIN} and
+@code{MPFR_PREC_MAX}.
+The
+precision of a variable means the number of bits used to store its significand.
+All
+subsequent calls to @code{mpfr_init} or @code{mpfr_inits}
+will use this precision, but previously
+initialized variables are unaffected.
+The default precision is set to 53 bits initially.
+
+Note: when MPFR is built with the @code{--enable-thread-safe} configure option,
+the default precision is local to each thread. @xref{Memory Handling}, for
+more information.
+@end deftypefun
+
+@deftypefun mpfr_prec_t mpfr_get_default_prec (void)
+Return the current default MPFR precision in bits.
+See the documentation of @code{mpfr_set_default_prec}.
+@end deftypefun
+
+@need 2000
+Here is an example on how to initialize floating-point variables:
+
+@example
+@{
+  mpfr_t x, y;
+  mpfr_init (x);                /* use default precision */
+  mpfr_init2 (y, 256);          /* precision @emph{exactly} 256 bits */
+  @dots{}
+  /* When the program is about to exit, do ... */
+  mpfr_clear (x);
+  mpfr_clear (y);
+  mpfr_free_cache ();           /* free the cache for constants like pi */
+@}
+@end example
+
+The following functions are useful for changing the precision during a
+calculation.  A typical use would be for adjusting the precision gradually in
+iterative algorithms like Newton-Raphson, making the computation precision
+closely match the actual accurate part of the numbers.
+
+@deftypefun void mpfr_set_prec (mpfr_t @var{x}, mpfr_prec_t @var{prec})
+Reset the precision of @var{x} to be @strong{exactly} @var{prec} bits,
+and set its value to NaN.
+The previous value stored in @var{x} is lost. It is equivalent to
+a call to @code{mpfr_clear(x)} followed by a call to
+@code{mpfr_init2(x, prec)}, but more efficient as no allocation is done in
+case the current allocated space for the significand of @var{x} is enough.
+The precision @var{prec} can be any integer between @code{MPFR_PREC_MIN} and
+@code{MPFR_PREC_MAX}.
+In case you want to keep the previous value stored in @var{x},
+use @code{mpfr_prec_round} instead.
+@end deftypefun
+
+@deftypefun mpfr_prec_t mpfr_get_prec (mpfr_t @var{x})

+character just after the valid data (if @var{endptr} is not a null pointer);
+otherwise @var{rop} is set to zero (for consistency with @code{strtod})
+and the value of @var{nptr} is stored
+in the location referenced by @var{endptr} (if @var{endptr} is not a null
+pointer). The usual ternary value is returned.
+
+Parsing follows the standard C @code{strtod} function with some extensions.
+After optional leading whitespace, one has a subject sequence consisting of an
+optional sign (@code{+} or @code{-}), and either numeric data or special
+data. The subject sequence is defined as the longest initial subsequence of
+the input string, starting with the first non-whitespace character, that is of
+the expected form.
+
+The form of numeric data is a non-empty sequence of significand digits with an
+optional decimal point, and an optional exponent consisting of an exponent
+prefix followed by an optional sign and a non-empty sequence of decimal
+digits. A significand digit is either a decimal digit or a Latin letter (62
+possible characters), with @code{A} = 10, @code{B} = 11, @dots{}, @code{Z} =
+35; case is ignored in bases less or equal to 36, in bases larger than 36,
+@code{a} = 36, @code{b} = 37, @dots{}, @code{z} = 61.
+The value of a
+significand digit must be strictly less than the base.  The decimal point can
+be either the one defined by the current locale or the period (the first one
+is accepted for consistency with the C standard and the practice, the second
+one is accepted to allow the programmer to provide MPFR numbers from strings
+in a way that does not depend on the current locale).
+The exponent prefix can be @code{e} or @code{E} for bases up to 10, or
+@code{@@} in any base; it indicates a multiplication by a power of the
+base. In bases 2 and 16, the exponent prefix can also be @code{p} or @code{P},
+in which case the exponent, called @emph{binary exponent}, indicates a
+multiplication by a power of 2 instead of the base (there is a difference
+only for base 16); in base 16 for example @code{1p2} represents 4 whereas
+@code{1@@2} represents 256. The value of an exponent is always written in
+base 10.
+
+If the argument @var{base} is 0, then the base is automatically detected
+as follows. If the significand starts with @code{0b} or @code{0B}, base 2
+is assumed. If the significand starts with @code{0x} or @code{0X}, base 16
+is assumed. Otherwise base 10 is assumed.
+
+Note: The exponent (if present)
+must contain at least a digit. Otherwise the possible
+exponent prefix and sign are not part of the number (which ends with the
+significand). Similarly, if @code{0b}, @code{0B}, @code{0x} or @code{0X}
+is not followed by a binary/hexadecimal digit, then the subject sequence
+stops at the character @code{0}, thus 0 is read.
+
+Special data (for infinities and NaN) can be @code{@@inf@@} or
+@code{@@nan@@(n-char-sequence-opt)}, and if @math{@var{base} @le{} 16},
+it can also be @code{infinity}, @code{inf}, @code{nan} or
+@code{nan(n-char-sequence-opt)}, all case insensitive.
+A @code{n-char-sequence-opt} is a possibly empty string containing only digits,
+Latin letters and the underscore (0, 1, 2, @dots{}, 9, a, b, @dots{}, z,
+A, B, @dots{}, Z, _). Note: one has an optional sign for all data, even
+NaN.
+For example, @code{-@@nAn@@(This_Is_Not_17)} is a valid representation for NaN
+in base 17.

+Convert @var{op} to a string of digits in base @var{b}, with rounding in
+the direction @var{rnd}, where @var{n} is either zero (see below) or the
+number of significant digits output in the string;
+in the latter case, @var{n} must be greater
+or equal to 2. The base may vary from 2 to 62.
+If the input number is an ordinary number, the exponent is written through
+the pointer @var{expptr} (for input 0, the current minimal exponent is
+written).
+
+The generated string is a fraction, with an implicit radix point immediately
+to the left of the first digit.  For example, the number @minus{}3.1416 would
+be returned as "@minus{}31416" in the string and 1 written at @var{expptr}.
+If @var{rnd} is to nearest, and @var{op} is exactly in the middle of two
+consecutive possible outputs, the one with an even significand is chosen,
+where both significands are considered with the exponent of @var{op}.
+Note that for an odd base, this may not correspond to an even last digit:
+for example with 2 digits in base 7, (14) and a half is rounded to (15)
+which is 12 in decimal, (16) and a half is rounded to
+(20) which is 14 in decimal,
+@c The following example duplicates (16) and a half
+@c (36) and a half is rounded to (40) which is 28 in decimal,
+and (26) and a half is rounded to (26) which is 20 in decimal.
+
+If @var{n} is zero, the number of digits of the significand is chosen
+large enough so that re-reading the printed value with the same precision,
+assuming both output and input use rounding to nearest, will recover
+the original value of @var{op}.
+More precisely, in most cases, the chosen precision of @var{str} is the
+minimal precision @math{m} depending only on @var{p} = PREC(@var{op}) and
+@var{b} that satisfies the above property, i.e.,
+@ifnottex
+m = 1 + ceil(@var{p}*log(2)/log(@var{b})),
+@end ifnottex
+@tex
+$m = 1 + \lceil p {\log 2 \over \log b} \rceil$,
+@end tex
+with @var{p} replaced by @var{p}@minus{}1 if @var{b} is a power of 2,
+but in some very rare cases, it might be @math{m+1}
+(the smallest case for bases up to 62 is when @var{p} equals 186564318007
+for bases 7 and 49).
+
+If @var{str} is a null pointer, space for the significand is allocated using
+the current allocation function, and a pointer to the string is returned.
+To free the returned string, you must use @code{mpfr_free_str}.
+
+If @var{str} is not a null pointer, it should point to a block of storage
+large enough for the significand, i.e., at least @code{max(@var{n} + 2, 7)}.
+The extra two bytes are for a possible minus sign, and for the terminating null
+character, and the value 7 accounts for @code{-@@Inf@@}
+plus the terminating null character.

+
+This section describes functions that perform input from an input/output

+Passing a null pointer for a @code{stream} to any of these functions will make
+them read from @code{stdin} and write to @code{stdout}, respectively.
+
+When using any of these functions, you must include the @code{<stdio.h>}

+prototypes for these functions.
+

+Output @var{op} on stream @var{stream}, as a string of digits in
+base @var{base}, rounded in the direction @var{rnd}.
+The base may vary from 2 to 62.  Print @var{n} significant digits exactly,
+or if @var{n} is 0, enough digits so that @var{op} can be read back
+exactly (see @code{mpfr_get_str}).
+
+In addition to the significant digits, a decimal point (defined by the
+current locale) at the right of the
+first digit and a trailing exponent in base 10, in the form @samp{eNNN},
+are printed. If @var{base} is greater than 10, @samp{@@} will be used
+instead of @samp{e} as exponent delimiter.

+@end deftypefun
+
+@deftypefun size_t mpfr_inp_str (mpfr_t @var{rop}, FILE *@var{stream}, int @var{base}, mpfr_rnd_t @var{rnd})

+rounded in the direction @var{rnd}, and put the
+read float in @var{rop}.
+@c The argument @var{base} must be in the range 2 to 62.
+
+@c The string is of the form @samp{M@@N} or, if the
+@c base is 10 or less, alternatively @samp{MeN} or @samp{MEN}, or, if the base
+@c is 16, alternatively @samp{MpB} or @samp{MPB}.
+@c @samp{M} is the significand in the specified base, @samp{N} is the exponent
+@c written in decimal for the specified base, and in base 16, @samp{B} is the
+@c binary exponent written in decimal (i.e., it indicates the power of 2 by
+@c which the significand is to be scaled).
+This function reads a word (defined as a sequence of characters between
+whitespace) and parses it using @code{mpfr_set_str}.
+See the documentation of @code{mpfr_strtofr} for a detailed description
+of the valid string formats.
+@c Special values can be read as follows (the case does not matter):

+@c possibly followed by other characters; if the base is smaller or equal
+@c to 16, the following strings are accepted too: @code{NaN}, @code{Inf},

+@section Formatted Output Functions
+
+@subsection Requirements
+The class of @code{mpfr_printf} functions provides formatted output in a
+similar manner as the standard C @code{printf}. These functions are defined
+only if your system supports ISO C variadic functions and the corresponding
+argument access macros.
+
+When using any of these functions, you must include the @code{<stdio.h>}
+standard header before @file{mpfr.h}, to allow @file{mpfr.h} to define
+prototypes for these functions.
+
+@subsection Format String
+The format specification accepted by @code{mpfr_printf} is an extension of the
+@code{printf} one. The conversion specification is of the form:
+@example
+% [flags] [width] [.[precision]] [type] [rounding] conv
+@end example
+@samp{flags}, @samp{width}, and @samp{precision} have the same meaning as for
+the standard @code{printf} (in particular, notice that the @samp{precision} is
+related to the number of digits displayed in the base chosen by @samp{conv}
+and not related to the internal precision of the @code{mpfr_t} variable).
+@code{mpfr_printf} accepts the same @samp{type} specifiers as GMP (except the
+non-standard and deprecated @samp{q}, use @samp{ll} instead), namely the
+length modifiers defined in the C standard:
+
+@quotation
+@multitable {(space)} {MMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMM}
+@item @samp{h}  @tab @code{short}
+@item @samp{hh} @tab @code{char}
+@item @samp{j}  @tab @code{intmax_t} or @code{uintmax_t}
+@item @samp{l}  @tab @code{long} or @code{wchar_t}
+@item @samp{ll} @tab @code{long long}
+@item @samp{L}  @tab @code{long double}
+@item @samp{t}  @tab @code{ptrdiff_t}
+@item @samp{z}  @tab @code{size_t}
+@end multitable
+@end quotation
+
+and the @samp{type} specifiers defined in GMP plus @samp{R} and @samp{P}
+specific to MPFR (the second column in the table below shows the type of the
+argument read in the argument list and the kind of @samp{conv} specifier to
+use after the @samp{type} specifier):
+
+@quotation
+@multitable {(space)} {MMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMM}
+@item @samp{F}  @tab @code{mpf_t}, float conversions
+@item @samp{Q}  @tab @code{mpq_t}, integer conversions
+@item @samp{M}  @tab @code{mp_limb_t}, integer conversions
+@item @samp{N}  @tab @code{mp_limb_t} array, integer conversions
+@item @samp{Z}  @tab @code{mpz_t}, integer conversions
+
+@item @samp{P}  @tab @code{mpfr_prec_t}, integer conversions
+@item @samp{R}  @tab @code{mpfr_t}, float conversions
+@end multitable
+@end quotation
+
+The @samp{type} specifiers have the same restrictions as those
+mentioned in the GMP documentation:
+@ifinfo
+@pxref{Formatted Output Strings,,, gmp.info,GNU MP}.
+@end ifinfo
+@ifnotinfo
+see Section ``Formatted Output Strings'' in @cite{GNU MP}.
+@end ifnotinfo
+In particular, the @samp{type} specifiers (except @samp{R} and @samp{P}) are
+supported only if they are supported by @code{gmp_printf} in your GMP build;
+this implies that the standard specifiers, such as @samp{t}, must @emph{also}
+be supported by your C library if you want to use them.
+
+The @samp{rounding} field is specific to @code{mpfr_t} arguments and should
+not be used with other types.
+
+With conversion specification not involving @samp{P} and @samp{R} types,
+@code{mpfr_printf} behaves exactly as @code{gmp_printf}.
+
+The @samp{P} type specifies that a following @samp{o}, @samp{u}, @samp{x}, or
+@samp{X} conversion specifier applies to a @code{mpfr_prec_t} argument.
+It is needed because the @code{mpfr_prec_t} type does not necessarily
+correspond to an @code{unsigned int} or any fixed standard type.
+The @samp{precision} field specifies the minimum number of digits to
+appear. The default @samp{precision} is 1.
+For example:
+@example
+mpfr_t x;
+mpfr_prec_t p;
+mpfr_init (x);
+@dots{}
+p = mpfr_get_prec (x);
+mpfr_printf ("variable x with %Pu bits", p);
+@end example
+
+The @samp{R} type specifies that a following @samp{a}, @samp{A}, @samp{b},
+@samp{e}, @samp{E}, @samp{f}, @samp{F}, @samp{g}, @samp{G}, or @samp{n}
+conversion specifier applies to a @code{mpfr_t} argument.
+The @samp{R} type can be followed by a @samp{rounding} specifier denoted by
+one of the following characters:
+
+@quotation
+@multitable {(space)} {MMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMM}
+@item @samp{U}  @tab round toward plus infinity
+@item @samp{D}  @tab round toward minus infinity
+@item @samp{Y}  @tab round away from zero
+@item @samp{Z}  @tab round toward zero
+@item @samp{N}  @tab round to nearest (with ties to even)
+@item @samp{*}  @tab rounding mode indicated by the @code{mpfr_rnd_t} argument
+just before the corresponding @code{mpfr_t} variable.
+@end multitable
+@end quotation
+
+The default rounding mode is rounding to nearest.
+The following three examples are equivalent:
+@example
+mpfr_t x;
+mpfr_init (x);
+@dots{}
+mpfr_printf ("%.128Rf", x);
+mpfr_printf ("%.128RNf", x);
+mpfr_printf ("%.128R*f", MPFR_RNDN, x);
+@end example
+
+Note that the rounding away from zero mode is specified with @samp{Y}
+because ISO C reserves the @samp{A} specifier for hexadecimal output (see
+below).
+
+The output @samp{conv} specifiers allowed with @code{mpfr_t} parameter are:
+
+@quotation
+@multitable {(space)} {MMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMM}
+@item @samp{a} @samp{A} @tab hex float, C99 style
+@item @samp{b}          @tab binary output
+@item @samp{e} @samp{E} @tab scientific format float
+@item @samp{f} @samp{F} @tab fixed point float
+@item @samp{g} @samp{G} @tab fixed or scientific float
+@end multitable
+@end quotation
+
+The conversion specifier @samp{b} which displays the argument in binary is
+specific to @code{mpfr_t} arguments and should not be used with other types.
+Other conversion specifiers have the same meaning as for a @code{double}
+argument.
+
+In case of non-decimal output, only the significand is written in the
+specified base, the exponent is always displayed in decimal.
+Special values are always displayed as @code{nan}, @code{-inf}, and @code{inf}
+for @samp{a}, @samp{b}, @samp{e}, @samp{f}, and @samp{g} specifiers and
+@code{NAN}, @code{-INF}, and @code{INF} for @samp{A}, @samp{E}, @samp{F}, and
+@samp{G} specifiers.
+
+If the @samp{precision} field is not empty, the @code{mpfr_t} number is
+rounded to the given precision in the direction specified by the rounding
+mode.
+If the precision is zero with rounding to nearest mode and one of the
+following @samp{conv} specifiers: @samp{a}, @samp{A}, @samp{b}, @samp{e},
+@samp{E}, tie case is rounded to even when it lies between two consecutive
+values at the
+wanted precision which have the same exponent, otherwise, it is rounded away
+from zero.
+For instance, 85 is displayed as "8e+1" and 95 is displayed as "1e+2" with the
+format specification @code{"%.0RNe"}.
+This also applies when the @samp{g} (resp. @samp{G}) conversion specifier uses
+the @samp{e} (resp. @samp{E}) style.
+If the precision is set to a value greater than the maximum value for an
+@code{int}, it will be silently reduced down to @code{INT_MAX}.
+
+If the @samp{precision} field is empty (as in @code{%Re} or @code{%.RE}) with
+@samp{conv} specifier @samp{e} and @samp{E}, the number is displayed with
+enough digits so that it can be read back exactly, assuming that the input and
+output variables have the same precision and that the input and output
+rounding modes are both rounding to nearest (as for @code{mpfr_get_str}).
+The default precision for an empty @samp{precision} field with @samp{conv}
+specifiers @samp{f}, @samp{F}, @samp{g}, and @samp{G} is 6.
+

+Set @var{rop} to @var{op} rounded to an integer.
+@code{mpfr_rint} rounds to the nearest representable integer in the

+to the next higher or equal representable integer, @code{mpfr_floor} to
+the next lower or equal representable integer, @code{mpfr_round} to the
+nearest representable integer, rounding halfway cases away from zero
+(as in the roundTiesToAway mode of IEEE 754-2008),
+and @code{mpfr_trunc} to the next representable integer toward zero.
+
+The returned value is zero when the result is exact, positive when it is
+greater than the original value of @var{op}, and negative when it is smaller.
+More precisely, the returned value is 0 when @var{op} is an integer
+representable in @var{rop}, 1 or @minus{}1 when @var{op} is an integer
+that is not representable in @var{rop}, 2 or @minus{}2 when @var{op} is
+not an integer.
+
+Note that @code{mpfr_round} is different from @code{mpfr_rint} called with
+the rounding to nearest mode (where halfway cases are rounded to an even
+integer or significand). Note also that no double rounding is performed; for
+instance, 10.5 (1010.1 in binary) is rounded by @code{mpfr_rint} with
+rounding to nearest to 12 (1100
+in binary) in 2-bit precision, because the two enclosing numbers representable
+on two bits are 8 and 12, and the closest is 12.

+The returned value is the ternary value associated with the considered

+For example, @code{mpfr_rint_round} with rounding to nearest and a precision

+(otherwise the behavior is undefined).
+If @var{prec} is greater or equal to the precision of @var{x}, then new

+and 0 otherwise (including for NaN and Inf).
+This function @strong{does not modify} its arguments.
+
+If @var{rnd1} is @code{MPFR_RNDN}, then the sign of the error is
+unknown, but its absolute value is the same, so that the possible range

+
+Note: if one wants to also determine the correct @ref{ternary value} when

+Indeed, if @var{rnd} is @code{MPFR_RNDN}, this will check if one can
+round to @var{prec}+1 bits with a directed rounding:
+if so, one can surely round to nearest to @var{prec} bits,

+allowed for @code{mpfr_set_emin} and @code{mpfr_set_emax} respectively.
+These values are implementation dependent, thus a program using
+@code{mpfr_set_emax(mpfr_get_emax_max())}
+or @code{mpfr_set_emin(mpfr_get_emin_min())} may not be portable.
+@end deftypefun
+
+@deftypefun int mpfr_check_range (mpfr_t @var{x}, int @var{t}, mpfr_rnd_t @var{rnd})
+This function assumes that @var{x} is the correctly-rounded value of some
+real value @var{y} in the direction @var{rnd} and some extended exponent
+range, and that @var{t} is the corresponding @ref{ternary value}.
+For example, one performed @code{t = mpfr_log (x, u, rnd)}, and @var{y} is the
+exact logarithm of @var{u}.
+Thus @var{t} is negative if @var{x} is smaller than @var{y},
+positive if @var{x} is larger than @var{y}, and zero if @var{x} equals @var{y}.
+This function modifies @var{x} if needed
+to be in the current range of acceptable values: It
+generates an underflow or an overflow if the exponent of @var{x} is
+outside the current allowed range; the value of @var{t} may be used
+to avoid a double rounding. This function returns zero if the new value of
+@var{x} equals the exact one @var{y}, a positive value if that new value
+is larger than @var{y}, and a negative value if it is smaller than @var{y}.
+Note that unlike most functions,
+the new result @var{x} is compared to the (unknown) exact one @var{y},
+not the input value @var{x}, i.e., the ternary value is propagated.
+
+Note: If @var{x} is an infinity and @var{t} is different from zero (i.e.,
+if the rounded result is an inexact infinity), then the overflow flag is
+set. This is useful because @code{mpfr_check_range} is typically called
+(at least in MPFR functions) after restoring the flags that could have
+been set due to internal computations.
+@end deftypefun
+
+@deftypefun int mpfr_subnormalize (mpfr_t @var{x}, int @var{t}, mpfr_rnd_t @var{rnd})
+This function rounds @var{x} emulating subnormal number arithmetic:
+if @var{x} is outside the subnormal exponent range, it just propagates the
+@ref{ternary value} @var{t}; otherwise, it rounds @var{x} to precision
+@code{EXP(x)-emin+1} according to rounding mode @var{rnd} and previous
+ternary value @var{t}, avoiding double rounding problems.
+More precisely in the subnormal domain, denoting by @var{e} the value of
+@code{emin}, @var{x} is rounded in fixed-point
+arithmetic to an integer multiple of @m{2^{e-1}, two to the power
+@var{e}@minus{}1}; as a consequence, @m{1.5 \times 2^{e-1},
+1.5 multiplied by two to the power @var{e}@minus{}1} when @var{t} is zero
+is rounded to @m{2^e, two to the power @var{e}} with rounding to nearest.
+
+@code{PREC(x)} is not modified by this function.
+@var{rnd} and @var{t} must be the rounding mode
+and the returned ternary value used when computing @var{x}
+(as in @code{mpfr_check_range}).
+The subnormal exponent range is from @code{emin} to @code{emin+PREC(x)-1}.
+If the result cannot be represented in the current exponent range
+(due to a too small @code{emax}), the behavior is undefined.
+Note that unlike most functions, the result is compared to the exact one,
+not the input value @var{x}, i.e., the ternary value is propagated.
+
+As usual, if the returned ternary value is non zero, the inexact flag is set.
+Moreover, if a second rounding occurred (because the input @var{x} was in the
+subnormal range), the underflow flag is set.

+All operations are then performed with the default MPFR rounding mode,
+which can be reset with @code{mpfr_set_default_rounding_mode}.
+
+Warning: the @code{mpf_init} and @code{mpf_init2} functions initialize

+Reset the precision of @var{x} to be @strong{exactly} @var{prec} bits.
+The only difference with @code{mpfr_set_prec} is that @var{prec} is assumed to

+@section Custom Interface
+
+Some applications use a stack to handle the memory and their objects.
+However, the MPFR memory design is not well suited for such a thing. So that
+such applications are able to use MPFR, an auxiliary memory interface has
+been created: the Custom Interface.
+
+The following interface allows one to use MPFR in two ways:
+@itemize
+@item Either directly store a floating-point number as a @code{mpfr_t}
+on the stack.
+@item Either store its own representation on the
+stack and construct a new temporary @code{mpfr_t} each time it is needed.
+@end itemize
+Nothing has to be done to destroy the floating-point
+numbers except garbaging the used
+memory: all the memory management (allocating, destroying, garbaging) is left
+to the application.
+
+Each function in this interface is also implemented as a macro for
+efficiency reasons: for example @code{mpfr_custom_init (s, p)}
+uses the macro, while @code{(mpfr_custom_init) (s, p)} uses the function.
+
+Note 1: MPFR functions may still initialize temporary floating-point numbers
+using @code{mpfr_init} and similar functions. See Custom Allocation (GNU MP).
+
+Note 2: MPFR functions may use the cached functions (@code{mpfr_const_pi} for
+example), even if they are not explicitly called. You have to call
+@code{mpfr_free_cache} each time you garbage the memory iff @code{mpfr_init},
+through GMP Custom Allocation, allocates its memory on the application stack.
+

+

+@itemize
+@item if @code{ABS(kind) == MPFR_NAN_KIND}, @var{x} is set to NaN;
+@item if @code{ABS(kind) == MPFR_INF_KIND}, @var{x} is set to the infinity

+@item if @code{ABS(kind) == MPFR_REGULAR_KIND}, @var{x} is set to a regular
+number: @code{x = sign(kind)*significand*2^exp}.
+@end itemize
+In all cases, it uses @var{significand} directly for further computing
+involving @var{x}. It will not allocate anything.
+A floating-point number initialized with this function cannot be resized using
+@code{mpfr_set_prec} or @code{mpfr_prec_round},

+@cindex Limb
+@c @tindex @code{mp_limb_t}
+@noindent
+A @dfn{limb} means the part of a multi-precision number that fits in a single
+word. Usually a limb contains
+32 or 64 bits.  The C data type for a limb is @code{mp_limb_t}.
+
+The @code{mpfr_t} type is internally defined as a one-element
+array of a structure, and @code{mpfr_ptr} is the C data type representing
+a pointer to this structure.
+The @code{mpfr_t} type consists of four fields:
+
+@itemize @bullet
+
+@item The @code{_mpfr_prec} field is used to store the precision of
+the variable (in bits); this is not less than @code{MPFR_PREC_MIN}.
+
+@item The @code{_mpfr_sign} field is used to store the sign of the variable.
+
+@item The @code{_mpfr_exp} field stores the exponent.
+An exponent of 0 means a radix point just above the most significant
+limb.  Non-zero values @math{n} are a multiplier @math{2^n} relative to that
+point.
+A NaN, an infinity and a zero are indicated by special values of the exponent
+field.
+
+@item Finally, the @code{_mpfr_d} field is a pointer to the limbs, least
+significant limbs stored first.
+The number of limbs in use is controlled by @code{_mpfr_prec}, namely
+ceil(@code{_mpfr_prec}/@code{mp_bits_per_limb}).
+Non-singular (i.e., different from NaN, Infinity or zero)
+values always have the most significant bit of the most
+significant limb set to 1.  When the precision does not correspond to a
+whole number of limbs, the excess bits at the low end of the data are zeros.

+@chapter API Compatibility
+
+The goal of this section is to describe some API changes that occurred
+from one version of MPFR to another, and how to write code that can be compiled
+and run with older MPFR versions.  The minimum MPFR version that is
+considered here is 2.2.0 (released on 20 September 2005).
+
+API changes can only occur between major or minor versions.  Thus the
+patchlevel (the third number in the MPFR version) will be ignored in
+the following.  If a program does not use MPFR internals, changes in
+the behavior between two versions differing only by the patchlevel
+should only result from what was regarded as a bug or unspecified behavior.
+@comment This includes undefined behavior.
+
+As a general rule, a program written for some MPFR version should work
+with later versions, possibly except at a new major version, where
+some features (described as obsolete for some time) can be removed.
+In such a case, a failure should occur during compilation or linking.
+If a result becomes incorrect because of such a change, please look
+at the various changes below (they are minimal, and most software
+should be unaffected), at the FAQ and at the MPFR web page for your
+version (a bug could have been introduced and be already fixed);
+and if the problem is not mentioned, please send us a bug report
+(@pxref{Reporting Bugs}).
+
+However, a program written for the current MPFR version (as documented
+by this manual) may not necessarily work with previous versions of
+MPFR.  This section should help developers to write portable code.
+
+Note: Information given here may be incomplete.  API changes are
+also described in the NEWS file (for each version, instead of being
+classified like here), together with other changes.

+@comment r6789
+The official type for exponent values changed from @code{mp_exp_t} to
+@code{mpfr_exp_t} in MPFR 3.0.  The type @code{mp_exp_t} will remain
+available as it comes from GMP (with a different meaning).  These types
+are currently the same (@code{mpfr_exp_t} is defined as @code{mp_exp_t}
+with @code{typedef}), so that programs can still use @code{mp_exp_t};
+but this may change in the future.
+Alternatively, using the following code after including @file{mpfr.h}
+will work with official MPFR versions, as @code{mpfr_exp_t} was never
+defined in MPFR 2.x:
+@example
+#if MPFR_VERSION_MAJOR < 3
+typedef mp_exp_t mpfr_exp_t;
+#endif
+@end example
+
+The official types for precision values and for rounding modes
+respectively changed from @code{mp_prec_t} and @code{mp_rnd_t}
+to @code{mpfr_prec_t} and @code{mpfr_rnd_t} in MPFR 3.0.  This
+change was actually done a long time ago in MPFR, at least since
+MPFR 2.2.0, with the following code in @file{mpfr.h}:
+@example
+#ifndef mp_rnd_t
+# define mp_rnd_t  mpfr_rnd_t
+#endif
+#ifndef mp_prec_t
+# define mp_prec_t mpfr_prec_t
+#endif
+@end example
+This means that it is safe to use the new official types
+@code{mpfr_prec_t} and @code{mpfr_rnd_t} in your programs.
+The types @code{mp_prec_t} and @code{mp_rnd_t} (defined
+in MPFR only) may be removed in the future, as the prefix
+@code{mp_} is reserved by GMP.
+
+@comment r6787
+The precision type @code{mpfr_prec_t} (@code{mp_prec_t}) was unsigned
+before MPFR 3.0; it is now signed.  @code{MPFR_PREC_MAX} has not changed,
+though.  Indeed the MPFR code requires that @code{MPFR_PREC_MAX} be
+representable in the exponent type, which may have the same size as
+@code{mpfr_prec_t} but has always been signed.
+The consequence is that valid code that does not assume anything about
+the signedness of @code{mpfr_prec_t} should work with past and new MPFR
+versions.
+This change was useful as the use of unsigned types tends to convert
+signed values to unsigned ones in expressions due to the usual arithmetic
+conversions, which can yield incorrect results if a negative value is
+converted in such a way.
+Warning!  A program assuming (intentionally or not) that
+@code{mpfr_prec_t} is signed may be affected by this problem when
+it is built and run against MPFR 2.x.
+
+The rounding modes @code{GMP_RNDx} were renamed to @code{MPFR_RNDx}
+in MPFR 3.0. However the old names @code{GMP_RNDx} have been kept for
+compatibility (this might change in future versions), using:
+@example
+#define GMP_RNDN MPFR_RNDN
+#define GMP_RNDZ MPFR_RNDZ
+#define GMP_RNDU MPFR_RNDU
+#define GMP_RNDD MPFR_RNDD
+@end example
+The rounding mode ``round away from zero'' (@code{MPFR_RNDA}) was added in
+MPFR 3.0 (however no rounding mode @code{GMP_RNDA} exists).

+@section Changed Functions
+
+The following functions have changed after MPFR 2.2. Changes can affect
+the behavior of code written for some MPFR version when built and run
+against another MPFR version (older or newer), as described below.
+
+@itemize @bullet
+
+@item @code{mpfr_check_range} changed in MPFR 2.3.2 and MPFR 2.4.
+If the value is an inexact infinity, the overflow flag is now set
+(in case it was lost), while it was previously left unchanged.
+This is really what is expected in practice (and what the MPFR code
+was expecting), so that the previous behavior was regarded as a bug.
+Hence the change in MPFR 2.3.2.
+
+@item @code{mpfr_get_f} changed in MPFR 3.0.
+This function was returning zero, except for NaN and Inf, which do not
+exist in MPF. The @emph{erange} flag is now set in these cases,
+and @code{mpfr_get_f} now returns the usual ternary value.
+
+@item @code{mpfr_get_si}, @code{mpfr_get_sj}, @code{mpfr_get_ui}
+and @code{mpfr_get_uj} changed in MPFR 3.0.
+In previous MPFR versions, the cases where the @emph{erange} flag
+is set were unspecified.
+
+@item @code{mpfr_get_z} changed in MPFR 3.0.
+The return type was @code{void}; it is now @code{int}, and the usual
+ternary value is returned.  Thus programs that need to work with both
+MPFR 2.x and 3.x must not use the return value.  Even in this case,
+C code using @code{mpfr_get_z} as the second or third term of
+a conditional operator may also be affected. For instance, the
+following is correct with MPFR 3.0, but not with MPFR 2.x:
+@example
+  bool ? mpfr_get_z(...) : mpfr_add(...);
+@end example
+On the other hand, the following is correct with MPFR 2.x, but not
+with MPFR 3.0:
+@example
+  bool ? mpfr_get_z(...) : (void) mpfr_add(...);
+@end example
+Portable code should cast @code{mpfr_get_z(...)} to @code{void} to
+use the type @code{void} for both terms of the conditional operator,
+as in:
+@example
+  bool ? (void) mpfr_get_z(...) : (void) mpfr_add(...);
+@end example
+Alternatively, @code{if ... else} can be used instead of the
+conditional operator.
+
+Moreover the cases where the @emph{erange} flag is set were unspecified
+in MPFR 2.x.
+
+@item @code{mpfr_get_z_exp} changed in MPFR 3.0.
+In previous MPFR versions, the cases where the @emph{erange} flag
+is set were unspecified.
+Note: this function has been renamed to @code{mpfr_get_z_2exp}
+in MPFR 3.0, but @code{mpfr_get_z_exp} is still available for
+compatibility reasons.
+
+@item @code{mpfr_strtofr} changed in MPFR 2.3.1 and MPFR 2.4.
+This was actually a bug fix since the code and the documentation did
+not match.  But both were changed in order to have a more consistent
+and useful behavior.  The main changes in the code are as follows.
+The binary exponent is now accepted even without the @code{0b} or
+@code{0x} prefix.  Data corresponding to NaN can now have an optional
+sign (such data were previously invalid).
+
+@item @code{mpfr_strtofr} changed in MPFR 3.0.
+This function now accepts bases from 37 to 62 (no changes for the other
+bases).  Note: if an unsupported base is provided to this function,
+the behavior is undefined; more precisely, in MPFR 2.3.1 and later,
+providing an unsupported base yields an assertion failure (this
+behavior may change in the future).
+
+@item @code{mpfr_subnormalize} changed in MPFR 3.1.
+This was actually regarded as a bug fix. The @code{mpfr_subnormalize}
+implementation up to MPFR 3.0.0 did not change the flags. In particular,
+it did not follow the generic rule concerning the inexact flag (and no
+special behavior was specified). The case of the underflow flag was more
+a lack of specification.
+
+@item @code{mpfr_urandom} and @code{mpfr_urandomb} changed in MPFR 3.1.
+Their behavior no longer depends on the platform (assuming this is also true
+for GMP's random generator, which is not the case between GMP 4.1 and 4.2 if
+@code{gmp_randinit_default} is used).  As a consequence, the returned values
+can be different between MPFR 3.1 and previous MPFR versions.
+Note: as the reproducibility of these functions was not specified
+before MPFR 3.1, the MPFR 3.1 behavior is @emph{not} regarded as
+backward incompatible with previous versions.

+@section Removed Functions
+
+Functions @code{mpfr_random} and @code{mpfr_random2} have been
+removed in MPFR 3.0 (this only affects old code built against
+MPFR 3.0 or later).
+(The function @code{mpfr_random} had been deprecated since at least MPFR 2.2.0,
+and @code{mpfr_random2} since MPFR 2.4.0.)

+@section Other Changes
+
+@comment r6699
+For users of a C++ compiler, the way how the availability of @code{intmax_t}
+is detected has changed in MPFR 3.0.
+In MPFR 2.x, if a macro @code{INTMAX_C} or @code{UINTMAX_C} was defined
+(e.g. when the @code{__STDC_CONSTANT_MACROS} macro had been defined
+before @code{<stdint.h>} or @code{<inttypes.h>} has been included),
+@code{intmax_t} was assumed to be defined.
+However this was not always the case (more precisely, @code{intmax_t}
+can be defined only in the namespace @code{std}, as with Boost), so
+that compilations could fail.
+Thus the check for @code{INTMAX_C} or @code{UINTMAX_C} is now disabled for
+C++ compilers, with the following consequences:
+
+@itemize
+
+@item Programs written for MPFR 2.x that need @code{intmax_t} may no longer
+be compiled against MPFR 3.0: a @code{#define MPFR_USE_INTMAX_T} may be
+necessary before @file{mpfr.h} is included.
+
+@item The compilation of programs that work with MPFR 3.0 may fail with
+MPFR 2.x due to the problem described above.  Workarounds are possible,
+such as defining @code{intmax_t} and @code{uintmax_t} in the global
+namespace, though this is not clean.
+
+@end itemize
+
+The divide-by-zero exception is new in MPFR 3.1. However it should
+not introduce incompatible changes for programs that strictly follow
+the MPFR API since the exception can only be seen via new functions.
+
+As of MPFR 3.1, the @file{mpfr.h} header can be included several times,
+while still supporting optional functions (@pxref{Headers and Libraries}).

+@unnumbered Contributors
+
+The main developers of MPFR are Guillaume Hanrot, Vincent Lef@`evre,
+Patrick P@'elissier, Philippe Th@'eveny and Paul Zimmermann.
+
+Sylvie Boldo from ENS-Lyon, France,
+contributed the functions @code{mpfr_agm} and @code{mpfr_log}.
+Sylvain Chevillard contributed the @code{mpfr_ai} function.
+David Daney contributed the hyperbolic and inverse hyperbolic functions,
+the base-2 exponential, and the factorial function.
+Alain Delplanque contributed the new version of the @code{mpfr_get_str}
+function.
+Mathieu Dutour contributed the functions @code{mpfr_acos}, @code{mpfr_asin}
+and @code{mpfr_atan}, and a previous version of @code{mpfr_gamma}.
+Laurent Fousse contributed the @code{mpfr_sum} function.
+Emmanuel Jeandel, from ENS-Lyon too,
+contributed the generic hypergeometric code,
+as well as the internal function @code{mpfr_exp3},
+a first implementation of the sine and cosine,
+and improved versions of
+@code{mpfr_const_log2} and @code{mpfr_const_pi}.
+Ludovic Meunier helped in the design of the @code{mpfr_erf} code.
+Jean-Luc R@'emy contributed the @code{mpfr_zeta} code.
+Fabrice Rouillier contributed the @code{mpfr_xxx_z} and @code{mpfr_xxx_q}
+functions, and helped to the Microsoft Windows porting.
+Damien Stehl@'e contributed the @code{mpfr_get_ld_2exp} function.
+
+We would like to thank Jean-Michel Muller and Joris van der Hoeven for very
+fruitful discussions at the beginning of that project, Torbj@"orn Granlund
+and Kevin Ryde for their help about design issues,
+and Nathalie Revol for her careful reading of a previous version of
+this documentation. In particular
+Kevin Ryde did a tremendous job for the portability of MPFR in 2002-2004.
+
+The development of the MPFR library would not have been possible without
+the continuous support of INRIA, and of the LORIA (Nancy, France) and LIP
+(Lyon, France) laboratories. In particular the main authors were or are
+members of the PolKA, Spaces, Cacao and Caramel
+project-teams at LORIA and of the
+Ar@'enaire and AriC project-teams at LIP.
+This project was started during the Fiable (reliable in French) action
+supported by INRIA, and continued during the AOC action.
+The development of MPFR was also supported by a grant
+(202F0659 00 MPN 121) from the Conseil R@'egional de Lorraine in 2002,
+from INRIA by an "associate engineer" grant (2003-2005),
+an "op@'eration de d@'eveloppement logiciel" grant (2007-2009),
+and the post-doctoral grant of Sylvain Chevillard in 2009-2010.
+The MPFR-MPC workshop in June 2012 was partly supported by the ERC
+grant ANTICS of Andreas Enge.

+% Output a mark which sets \thischapter, \thissection and \thiscolor.

+% @multitable macros
+% Amy Hendrickson, 8/18/94, 3/6/96
+%
+% @multitable ... @end multitable will make as many columns as desired.
+% Contents of each column will wrap at width given in preamble.  Width
+% can be specified either with sample text given in a template line,
+% or in percent of \hsize, the current width of text on page.
+
+% Table can continue over pages but will only break between lines.
+
+% To make preamble:
+%
+% Either define widths of columns in terms of percent of \hsize:
+%   @multitable @columnfractions .25 .3 .45
+%   @item ...
+%
+%   Numbers following @columnfractions are the percent of the total
+%   current hsize to be used for each column. You may use as many
+%   columns as desired.
+
+
+% Or use a template:
+%   @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+%   @item ...
+%   using the widest term desired in each column.
+
+% Each new table line starts with @item, each subsequent new column
+% starts with @tab. Empty columns may be produced by supplying @tab's
+% with nothing between them for as many times as empty columns are needed,
+% ie, @tab@tab@tab will produce two empty columns.
+
+% @item, @tab do not need to be on their own lines, but it will not hurt
+% if they are.
+
+% Sample multitable:
+
+%   @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+%   @item first col stuff @tab second col stuff @tab third col
+%   @item
+%   first col stuff
+%   @tab
+%   second col stuff
+%   @tab
+%   third col
+%   @item first col stuff @tab second col stuff
+%   @tab Many paragraphs of text may be used in any column.
+%
+%         They will wrap at the width determined by the template.
+%   @item@tab@tab This will be in third column.
+%   @end multitable
+
+% Default dimensions may be reset by user.
+% @multitableparskip is vertical space between paragraphs in table.
+% @multitableparindent is paragraph indent in table.
+% @multitablecolmargin is horizontal space to be left between columns.

+% This macro is used to make a character print one way in \tt

+% #1 is what to print if we are indeed using \tt; #2 is what to print

+% interword stretch (and shrink), and it is reasonable to expect all

+% The story here is that in math mode, the \char of \backslashcurfont
+% ends up printing the roman \ from the math symbol font (because \char
+% in math mode uses the \mathcode, and plain.tex sets
+% \mathcode`\\="026E).  It seems better for @backslashchar{} to always
+% print a typewriter backslash, hence we use an explicit \mathchar,

+% On the other hand, perhaps the file did not have a `\input texinfo'. Then

+# which have later been changed to m4_define as they aren't part of the
+# exported API, or moved to Autoconf or Automake where they belong.
+#
+# The trouble is, aclocal is a bit thick.  It'll see the old AC_DEFUN
+# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
+# using a macro with the same name in our local m4/libtool.m4 it'll
+# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
+# and doesn't know about Autoconf macros at all.)

+# included after everything else.  This provides aclocal with the
+# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
+# because those macros already exist, or will be overwritten later.
+# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6. 
+#
+# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.

+     We know from "Bound on Runs of Zeros and Ones for Algebraic Functions",
+     Proceedings of Arith15, T. Lang and J.-M. Muller, 2001, that the maximal
+     number of consecutive zeroes or ones after the round bit is n-1 for an
+     input of n bits. But we need a more precise lower bound. Assume x has
+     n bits, and 1/x is near a floating-point number y of n+1 bits. We can
+     write x = X*2^e, y = Y/2^f with X, Y integers of n and n+1 bits.
+     Thus X*Y^2^(e-f) is near from 1, i.e., X*Y is near from 2^(f-e).
+     Two cases can happen:
+     (i) either X*Y is exactly 2^(f-e), but this can happen only if X and Y
+         are themselves powers of two, i.e., x is a power of two;
+     (ii) or X*Y is at distance at least one from 2^(f-e), thus
+          |xy-1| >= 2^(e-f), or |y-1/x| >= 2^(e-f)/x = 2^(-f)/X >= 2^(-f-n).
+          Since ufp(y) = 2^(n-f) [ufp = unit in first place], this means
+          that the distance |y-1/x| >= 2^(-2n) ufp(y).
+          Now assuming |gamma(x)-1/x| <= 1, which is true for x <= 1,

+/* Define auxiliary asm macros.
+
+   1) umul_ppmm(high_prod, low_prod, multiplier, multiplicand) multiplies two
+   UWtype integers MULTIPLIER and MULTIPLICAND, and generates a two UWtype
+   word product in HIGH_PROD and LOW_PROD.
+
+   2) __umulsidi3(a,b) multiplies two UWtype integers A and B, and returns a
+   UDWtype product.  This is just a variant of umul_ppmm.
+
+   3) udiv_qrnnd(quotient, remainder, high_numerator, low_numerator,
+   denominator) divides a UDWtype, composed by the UWtype integers
+   HIGH_NUMERATOR and LOW_NUMERATOR, by DENOMINATOR and places the quotient
+   in QUOTIENT and the remainder in REMAINDER.  HIGH_NUMERATOR must be less
+   than DENOMINATOR for correct operation.  If, in addition, the most
+   significant bit of DENOMINATOR must be 1, then the pre-processor symbol
+   UDIV_NEEDS_NORMALIZATION is defined to 1.
+
+   4) sdiv_qrnnd(quotient, remainder, high_numerator, low_numerator,
+   denominator).  Like udiv_qrnnd but the numbers are signed.  The quotient
+   is rounded toward 0.
+
+   5) count_leading_zeros(count, x) counts the number of zero-bits from the
+   msb to the first non-zero bit in the UWtype X.  This is the number of
+   steps X needs to be shifted left to set the msb.  Undefined for X == 0,
+   unless the symbol COUNT_LEADING_ZEROS_0 is defined to some value.
+
+   6) count_trailing_zeros(count, x) like count_leading_zeros, but counts
+   from the least significant end.
+
+   7) add_ssaaaa(high_sum, low_sum, high_addend_1, low_addend_1,
+   high_addend_2, low_addend_2) adds two UWtype integers, composed by
+   HIGH_ADDEND_1 and LOW_ADDEND_1, and HIGH_ADDEND_2 and LOW_ADDEND_2
+   respectively.  The result is placed in HIGH_SUM and LOW_SUM.  Overflow
+   (i.e. carry out) is not stored anywhere, and is lost.
+
+   8) sub_ddmmss(high_difference, low_difference, high_minuend, low_minuend,
+   high_subtrahend, low_subtrahend) subtracts two two-word UWtype integers,
+   composed by HIGH_MINUEND_1 and LOW_MINUEND_1, and HIGH_SUBTRAHEND_2 and
+   LOW_SUBTRAHEND_2 respectively.  The result is placed in HIGH_DIFFERENCE
+   and LOW_DIFFERENCE.  Overflow (i.e. carry out) is not stored anywhere,
+   and is lost.
+
+   If any of these macros are left undefined for a particular CPU,
+   C macros are used.
+
+
+   Notes:
+
+   For add_ssaaaa the two high and two low addends can both commute, but
+   unfortunately gcc only supports one "%" commutative in each asm block.
+   This has always been so but is only documented in recent versions
+   (eg. pre-release 3.3).  Having two or more "%"s can cause an internal
+   compiler error in certain rare circumstances.
+
+   Apparently it was only the last "%" that was ever actually respected, so
+   the code has been updated to leave just that.  Clearly there's a free
+   choice whether high or low should get it, if there's a reason to favour
+   one over the other.  Also obviously when the constraints on the two
+   operands are identical there's no benefit to the reloader in any "%" at
+   all.
+

+/* count_leading_zeros_gcc_clz is count_leading_zeros implemented with gcc
+   3.4 __builtin_clzl or __builtin_clzll, according to our limb size.
+   Similarly count_trailing_zeros_gcc_ctz using __builtin_ctzl or
+   __builtin_ctzll.
+
+   These builtins are only used when we check what code comes out, on some
+   chips they're merely libgcc calls, where we will instead want an inline
+   in that case (either asm or generic C).
+
+   These builtins are better than an asm block of the same insn, since an
+   asm block doesn't give gcc any information about scheduling or resource
+   usage.  We keep an asm block for use on prior versions of gcc though.
+
+   For reference, __builtin_ffs existed in gcc prior to __builtin_clz, but
+   it's not used (for count_leading_zeros) because it generally gives extra
+   code to ensure the result is 0 when the input is 0, which we don't need

+   use such extensions, but these macros will be used by 3rd-party code,

+   Moreover casts to unsigned long have been added to avoid warnings in
+   programs that use MPFR and are compiled with -Wconversion; such casts
+   are OK since if X is a constant expression, then (unsigned long) X is
+   also a constant expression, so that the optimizations still work. The

+     http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38470 (possibly a variant)
+   and the casts could be removed once these bugs are fixed.
+   Casts shouldn't be used on the generic calls (to the ..._2exp functions),
+   where implicit conversions are performed. Indeed, having at least one
+   implicit conversion in the macro allows the compiler to emit diagnostics
+   when normally expected, for instance in the following call:
+     mpfr_set_ui (x, "foo", MPFR_RNDN);

+
+   We have 1 <= A < 4 and 1/2 <= X < 1.
+
+   The error in the approximate result with respect to the true
+   value 1/sqrt(A) is bounded by 1 ulp(X), i.e., 2^{-p} since 1/2 <= X < 1.
+
+   Note: x and a are left-aligned, i.e., the most significant bit of
+   a[an-1] is set, and so is the most significant bit of the output x[n-1].
+
+   If p is not a multiple of GMP_NUMB_BITS, the extra low bits of the input
+   A are taken into account to compute the approximation of 1/sqrt(A), but
+   whether or not they are zero, the error between X and 1/sqrt(A) is bounded
+   by 1 ulp(X) [in precision p].
+   The extra low bits of the output X (if p is not a multiple of GMP_NUMB_BITS)
+   are set to 0.
+
+   Assumptions:
+   (1) A should be normalized, i.e., the most significant bit of a[an-1]
+       should be 1. If as=0, we have 1 <= A < 2; if as=1, we have 2 <= A < 4.
+   (2) p >= 12
+   (3) {a, an} and {x, n} should not overlap
+   (4) GMP_NUMB_BITS >= 12 and is even
+
+   Note: this routine is much more efficient when ap is small compared to p,
+   including the case where ap <= GMP_NUMB_BITS, thus it can be used to
+   implement an efficient mpfr_rec_sqrt_ui function.
