-What's new in FDLIBM 5.3?
-
-CONFIGURE
-        To build FDLIBM, edit the supplied Makefile or create
-        a local Makefile by running "sh configure"
-        using the supplied configure script contributed by Nelson Beebe
-
-BUGS FIXED
-
-    1. e_pow.c incorrect results when
-        x is very close to -1.0 and y is very large, e.g.
-        ieee_pow(-1.0000000000000002e+00,4.5035996273704970e+15) = 0
-        ieee_pow(-9.9999999999999978e-01,4.5035996273704970e+15) = 0
-        Correct results are close to -e and -1/e.
-
-    2. k_tan.c error was > 1 ulp target for FDLIBM
-        5.2: Worst error at least 1.45 ulp at
-        ieee_tan(1.7765241907548024E+269) = 1.7733884462610958E+16
-        5.3: Worst error 0.96 ulp
-
-NOT FIXED YET
-
-    3. Compiler failure on non-standard code
-        Statements like
-                    *(1+(int*)&t1) = 0;
-        are not standard C and cause some optimizing compilers (e.g. GCC)
-        to generate bad code under optimization.    These cases
-        are to be addressed in the next release.

-/* __ieee754_exp(x)
- * Returns the exponential of x.
- *
- * Method
- *   1. Argument reduction:
- *      Reduce x to an r so that |r| <= 0.5*ln2 ~ 0.34658.
- *	Given x, find r and integer k such that
- *
- *               x = k*ln2 + r,  |r| <= 0.5*ln2.  
- *
- *      Here r will be represented as r = hi-lo for better 
- *	accuracy.
- *
- *   2. Approximation of ieee_exp(r) by a special rational function on
- *	the interval [0,0.34658]:
- *	Write
- *	    R(r**2) = r*(ieee_exp(r)+1)/(ieee_exp(r)-1) = 2 + r*r/6 - r**4/360 + ...
- *      We use a special Remes algorithm on [0,0.34658] to generate 
- * 	a polynomial of degree 5 to approximate R. The maximum error 
- *	of this polynomial approximation is bounded by 2**-59. In
- *	other words,
- *	    R(z) ~ 2.0 + P1*z + P2*z**2 + P3*z**3 + P4*z**4 + P5*z**5
- *  	(where z=r*r, and the values of P1 to P5 are listed below)
- *	and
- *	    |                  5          |     -59
- *	    | 2.0+P1*z+...+P5*z   -  R(z) | <= 2 
- *	    |                             |
- *	The computation of ieee_exp(r) thus becomes
- *                             2*r
- *		exp(r) = 1 + -------
- *		              R - r
- *                                 r*R1(r)	
- *		       = 1 + r + ----------- (for better accuracy)
- *		                  2 - R1(r)
- *	where
- *			         2       4             10
- *		R1(r) = r - (P1*r  + P2*r  + ... + P5*r   ).
- *	
- *   3. Scale back to obtain ieee_exp(x):
- *	From step 1, we have
- *	   ieee_exp(x) = 2^k * ieee_exp(r)
- *
- * Special cases:
- *	exp(INF) is INF, ieee_exp(NaN) is NaN;
- *	exp(-INF) is 0, and
- *	for finite argument, only ieee_exp(0)=1 is exact.
- *
- * Accuracy:
- *	according to an error analysis, the error is always less than
- *	1 ulp (unit in the last place).
- *
- * Misc. info.
- *	For IEEE double 
- *	    if x >  7.09782712893383973096e+02 then ieee_exp(x) overflow
- *	    if x < -7.45133219101941108420e+02 then ieee_exp(x) underflow
- *
- * Constants:
- * The hexadecimal values are the intended ones for the following 
- * constants. The decimal values may be used, provided that the 
- * compiler will convert from decimal to binary accurately enough
- * to produce the hexadecimal values shown.

-/* __ieee754_j0(x), __ieee754_y0(x)
- * Bessel function of the first and second kinds of order zero.
- * Method -- ieee_j0(x):
- *	1. For tiny x, we use ieee_j0(x) = 1 - x^2/4 + x^4/64 - ...
- *	2. Reduce x to |x| since ieee_j0(x)=ieee_j0(-x),  and
- *	   for x in (0,2)
- *		j0(x) = 1-z/4+ z^2*R0/S0,  where z = x*x;
- *	   (precision:  |j0-1+z/4-z^2R0/S0 |<2**-63.67 )
- *	   for x in (2,inf)
- * 		j0(x) = ieee_sqrt(2/(pi*x))*(p0(x)*ieee_cos(x0)-q0(x)*ieee_sin(x0))
- * 	   where x0 = x-pi/4. It is better to compute ieee_sin(x0),cos(x0)
- *	   as follow:
- *		cos(x0) = ieee_cos(x)cos(pi/4)+ieee_sin(x)sin(pi/4)
- *			= 1/ieee_sqrt(2) * (ieee_cos(x) + ieee_sin(x))
- *		sin(x0) = ieee_sin(x)cos(pi/4)-ieee_cos(x)sin(pi/4)
- *			= 1/ieee_sqrt(2) * (ieee_sin(x) - ieee_cos(x))
- * 	   (To avoid cancellation, use
- *		sin(x) +- ieee_cos(x) = -ieee_cos(2x)/(ieee_sin(x) -+ ieee_cos(x))
- * 	    to compute the worse one.)
- *	   
- *	3 Special cases
- *		j0(nan)= nan
- *		j0(0) = 1
- *		j0(inf) = 0
- *		
- * Method -- ieee_y0(x):
- *	1. For x<2.
- *	   Since 
- *		y0(x) = 2/pi*(ieee_j0(x)*(ln(x/2)+Euler) + x^2/4 - ...)
- *	   therefore ieee_y0(x)-2/pi*ieee_j0(x)*ln(x) is an even function.
- *	   We use the following function to approximate y0,
- *		y0(x) = U(z)/V(z) + (2/pi)*(ieee_j0(x)*ln(x)), z= x^2
- *	   where 
- *		U(z) = u00 + u01*z + ... + u06*z^6
- *		V(z) = 1  + v01*z + ... + v04*z^4
- *	   with absolute approximation error bounded by 2**-72.
- *	   Note: For tiny x, U/V = u0 and ieee_j0(x)~1, hence
- *		y0(tiny) = u0 + (2/pi)*ln(tiny), (choose tiny<2**-27)
- *	2. For x>=2.
- * 		y0(x) = ieee_sqrt(2/(pi*x))*(p0(x)*ieee_cos(x0)+q0(x)*ieee_sin(x0))
- * 	   where x0 = x-pi/4. It is better to compute ieee_sin(x0),cos(x0)
- *	   by the method mentioned above.
- *	3. Special cases: ieee_y0(0)=-inf, ieee_y0(x<0)=NaN, ieee_y0(inf)=0.

-/* __ieee754_j1(x), __ieee754_y1(x)
- * Bessel function of the first and second kinds of order zero.
- * Method -- ieee_j1(x):
- *	1. For tiny x, we use ieee_j1(x) = x/2 - x^3/16 + x^5/384 - ...
- *	2. Reduce x to |x| since ieee_j1(x)=-ieee_j1(-x),  and
- *	   for x in (0,2)
- *		j1(x) = x/2 + x*z*R0/S0,  where z = x*x;
- *	   (precision:  |j1/x - 1/2 - R0/S0 |<2**-61.51 )
- *	   for x in (2,inf)
- * 		j1(x) = ieee_sqrt(2/(pi*x))*(p1(x)*ieee_cos(x1)-q1(x)*ieee_sin(x1))
- * 		y1(x) = ieee_sqrt(2/(pi*x))*(p1(x)*ieee_sin(x1)+q1(x)*ieee_cos(x1))
- * 	   where x1 = x-3*pi/4. It is better to compute ieee_sin(x1),cos(x1)
- *	   as follow:
- *		cos(x1) =  ieee_cos(x)cos(3pi/4)+ieee_sin(x)sin(3pi/4)
- *			=  1/ieee_sqrt(2) * (ieee_sin(x) - ieee_cos(x))
- *		sin(x1) =  ieee_sin(x)cos(3pi/4)-ieee_cos(x)sin(3pi/4)
- *			= -1/ieee_sqrt(2) * (ieee_sin(x) + ieee_cos(x))
- * 	   (To avoid cancellation, use
- *		sin(x) +- ieee_cos(x) = -ieee_cos(2x)/(ieee_sin(x) -+ ieee_cos(x))
- * 	    to compute the worse one.)
- *	   
- *	3 Special cases
- *		j1(nan)= nan
- *		j1(0) = 0
- *		j1(inf) = 0
- *		
- * Method -- ieee_y1(x):
- *	1. screen out x<=0 cases: ieee_y1(0)=-inf, ieee_y1(x<0)=NaN 
- *	2. For x<2.
- *	   Since 
- *		y1(x) = 2/pi*(ieee_j1(x)*(ln(x/2)+Euler)-1/x-x/2+5/64*x^3-...)
- *	   therefore ieee_y1(x)-2/pi*ieee_j1(x)*ln(x)-1/x is an odd function.
- *	   We use the following function to approximate y1,
- *		y1(x) = x*U(z)/V(z) + (2/pi)*(ieee_j1(x)*ln(x)-1/x), z= x^2
- *	   where for x in [0,2] (abs err less than 2**-65.89)
- *		U(z) = U0[0] + U0[1]*z + ... + U0[4]*z^4
- *		V(z) = 1  + v0[0]*z + ... + v0[4]*z^5
- *	   Note: For tiny x, 1/x dominate y1 and hence
- *		y1(tiny) = -2/pi/tiny, (choose tiny<2**-54)
- *	3. For x>=2.
- * 		y1(x) = ieee_sqrt(2/(pi*x))*(p1(x)*ieee_sin(x1)+q1(x)*ieee_cos(x1))
- * 	   where x1 = x-3*pi/4. It is better to compute ieee_sin(x1),cos(x1)
- *	   by method mentioned above.

-/* __ieee754_lgamma_r(x, signgamp)
- * Reentrant version of the logarithm of the Gamma function 
- * with user provide pointer for the sign of Gamma(x). 
- *
- * Method:
- *   1. Argument Reduction for 0 < x <= 8
- * 	Since ieee_gamma(1+s)=s*ieee_gamma(s), for x in [0,8], we may 
- * 	reduce x to a number in [1.5,2.5] by
- * 		lgamma(1+s) = ieee_log(s) + ieee_lgamma(s)
- *	for example,
- *		lgamma(7.3) = ieee_log(6.3) + ieee_lgamma(6.3)
- *			    = ieee_log(6.3*5.3) + ieee_lgamma(5.3)
- *			    = ieee_log(6.3*5.3*4.3*3.3*2.3) + ieee_lgamma(2.3)
- *   2. Polynomial approximation of lgamma around its
- *	minimun ymin=1.461632144968362245 to maintain monotonicity.
- *	On [ymin-0.23, ymin+0.27] (i.e., [1.23164,1.73163]), use
- *		Let z = x-ymin;
- *		lgamma(x) = -1.214862905358496078218 + z^2*poly(z)
- *	where
- *		poly(z) is a 14 degree polynomial.
- *   2. Rational approximation in the primary interval [2,3]
- *	We use the following approximation:
- *		s = x-2.0;
- *		lgamma(x) = 0.5*s + s*P(s)/Q(s)
- *	with accuracy
- *		|P/Q - (ieee_lgamma(x)-0.5s)| < 2**-61.71
- *	Our algorithms are based on the following observation
- *
- *                             zeta(2)-1    2    zeta(3)-1    3
- * ieee_lgamma(2+s) = s*(1-Euler) + --------- * s  -  --------- * s  + ...
- *                                 2                 3
- *
- *	where Euler = 0.5771... is the Euler constant, which is very
- *	close to 0.5.
- *
- *   3. For x>=8, we have
- *	lgamma(x)~(x-0.5)log(x)-x+0.5*ieee_log(2pi)+1/(12x)-1/(360x**3)+....
- *	(better formula:
- *	   ieee_lgamma(x)~(x-0.5)*(ieee_log(x)-1)-.5*(ieee_log(2pi)-1) + ...)
- *	Let z = 1/x, then we approximation
- *		f(z) = ieee_lgamma(x) - (x-0.5)(ieee_log(x)-1)
- *	by
- *	  			    3       5             11
- *		w = w0 + w1*z + w2*z  + w3*z  + ... + w6*z
- *	where 
- *		|w - f(z)| < 2**-58.74
- *		
- *   4. For negative x, since (G is gamma function)
- *		-x*G(-x)*G(x) = pi/ieee_sin(pi*x),
- * 	we have
- * 		G(x) = pi/(ieee_sin(pi*x)*(-x)*G(-x))
- *	since G(-x) is positive, sign(G(x)) = sign(ieee_sin(pi*x)) for x<0
- *	Hence, for x<0, signgam = sign(ieee_sin(pi*x)) and 
- *		lgamma(x) = ieee_log(|Gamma(x)|)
- *			  = ieee_log(pi/(|x*ieee_sin(pi*x)|)) - ieee_lgamma(-x);
- *	Note: one should avoid compute pi*(-x) directly in the 
- *	      computation of ieee_sin(pi*(-x)).
- *		
- *   5. Special Cases
- *		lgamma(2+s) ~ s*(1-Euler) for tiny s
- *		lgamma(1)=ieee_lgamma(2)=0
- *		lgamma(x) ~ -ieee_log(x) for tiny x
- *		lgamma(0) = ieee_lgamma(inf) = inf
- *	 	lgamma(-integer) = +-inf

-/* __ieee754_log(x)
- * Return the logrithm of x
- *
- * Method :                  
- *   1. Argument Reduction: find k and f such that 
- *			x = 2^k * (1+f), 
- *	   where  ieee_sqrt(2)/2 < 1+f < ieee_sqrt(2) .
- *
- *   2. Approximation of ieee_log(1+f).
- *	Let s = f/(2+f) ; based on ieee_log(1+f) = ieee_log(1+s) - ieee_log(1-s)
- *		 = 2s + 2/3 s**3 + 2/5 s**5 + .....,
- *	     	 = 2s + s*R
- *      We use a special Reme algorithm on [0,0.1716] to generate 
- * 	a polynomial of degree 14 to approximate R The maximum error 
- *	of this polynomial approximation is bounded by 2**-58.45. In
- *	other words,
- *		        2      4      6      8      10      12      14
- *	    R(z) ~ Lg1*s +Lg2*s +Lg3*s +Lg4*s +Lg5*s  +Lg6*s  +Lg7*s
- *  	(the values of Lg1 to Lg7 are listed in the program)
- *	and
- *	    |      2          14          |     -58.45
- *	    | Lg1*s +...+Lg7*s    -  R(z) | <= 2 
- *	    |                             |
- *	Note that 2s = f - s*f = f - hfsq + s*hfsq, where hfsq = f*f/2.
- *	In order to guarantee error in log below 1ulp, we compute log
- *	by
- *		log(1+f) = f - s*(f - R)	(if f is not too large)
- *		log(1+f) = f - (hfsq - s*(hfsq+R)).	(better accuracy)
- *	
- *	3. Finally,  ieee_log(x) = k*ln2 + ieee_log(1+f).  
- *			    = k*ln2_hi+(f-(hfsq-(s*(hfsq+R)+k*ln2_lo)))
- *	   Here ln2 is split into two floating point number: 
- *			ln2_hi + ln2_lo,
- *	   where n*ln2_hi is always exact for |n| < 2000.
- *
- * Special cases:
- *	log(x) is NaN with signal if x < 0 (including -INF) ; 
- *	log(+INF) is +INF; ieee_log(0) is -INF with signal;
- *	log(NaN) is that NaN with no signal.
- *
- * Accuracy:
- *	according to an error analysis, the error is always less than
- *	1 ulp (unit in the last place).
- *
- * Constants:
- * The hexadecimal values are the intended ones for the following 
- * constants. The decimal values may be used, provided that the 
- * compiler will convert from decimal to binary accurately enough 
- * to produce the hexadecimal values shown.

- * Return the base 10 logarithm of x
- * 
- * Method :

- *	    log10_2lo = ieee_log10(2) - log10_2hi,
- *	    ivln10   = 1/ieee_log(10) rounded.

- *		log10(x) := n*log10_2hi + (n*log10_2lo + ivln10*ieee_log(x))
- *
- * Note 1:
- *	To guarantee ieee_log10(10**n)=n, where 10**n is normal, the rounding 
- *	mode must set to Round-to-Nearest.
- * Note 2:
- *	[1/ieee_log(10)] rounded to 53 bits has error  .198   ulps;
- *	log10 is monotonic at all binary break points.
- *
- * Special cases:
- *	log10(x) is NaN with signal if x < 0; 
- *	log10(+INF) is +INF with no signal; ieee_log10(0) is -INF with signal;
- *	log10(NaN) is that NaN with no signal;
- *	log10(10**N) = N  for N=0,1,...,22.
- *
- * Constants:
- * The hexadecimal values are the intended ones for the following constants.
- * The decimal values may be used, provided that the compiler will convert
- * from decimal to binary accurately enough to produce the hexadecimal values
- * shown.

-/* __ieee754_sqrt(x)
- * Return correctly rounded sqrt.
- *           ------------------------------------------
- *	     |  Use the hardware sqrt if you have one |
- *           ------------------------------------------
- * Method: 
- *   Bit by bit method using integer arithmetic. (Slow, but portable) 
- *   1. Normalization
- *	Scale x to y in [1,4) with even powers of 2: 
- *	find an integer k such that  1 <= (y=x*2^(2k)) < 4, then
- *		sqrt(x) = 2^k * ieee_sqrt(y)
- *   2. Bit by bit computation
- *	Let q  = ieee_sqrt(y) truncated to i bit after binary point (q = 1),
- *	     i							 0
- *                                     i+1         2
- *	    s  = 2*q , and	y  =  2   * ( y - q  ).		(1)
- *	     i      i            i                 i
- *                                                        
- *	To compute q    from q , one checks whether 
- *		    i+1       i                       
- *
- *			      -(i+1) 2
- *			(q + 2      ) <= y.			(2)
- *     			  i
- *							      -(i+1)
- *	If (2) is false, then q   = q ; otherwise q   = q  + 2      .
- *		 	       i+1   i             i+1   i
- *
- *	With some algebric manipulation, it is not difficult to see
- *	that (2) is equivalent to 
- *                             -(i+1)
- *			s  +  2       <= y			(3)
- *			 i                i
- *
- *	The advantage of (3) is that s  and y  can be computed by 
- *				      i      i
- *	the following recurrence formula:
- *	    if (3) is false
- *
- *	    s     =  s  ,	y    = y   ;			(4)
- *	     i+1      i		 i+1    i
- *
- *	    otherwise,
- *                         -i                     -(i+1)
- *	    s	  =  s  + 2  ,  y    = y  -  s  - 2  		(5)
- *           i+1      i          i+1    i     i
- *				
- *	One may easily use induction to prove (4) and (5). 
- *	Note. Since the left hand side of (3) contain only i+2 bits,
- *	      it does not necessary to do a full (53-bit) comparison 
- *	      in (3).
- *   3. Final rounding
- *	After generating the 53 bits result, we compute one more bit.
- *	Together with the remainder, we can decide whether the
- *	result is exact, bigger than 1/2ulp, or less than 1/2ulp
- *	(it will never equal to 1/2ulp).
- *	The rounding mode can be detected by checking whether
- *	huge + tiny is equal to huge, and whether huge - tiny is
- *	equal to huge for some floating point number "huge" and "tiny".
- *		
- * Special cases:
- *	sqrt(+-0) = +-0 	... exact
- *	sqrt(inf) = inf
- *	sqrt(-ve) = NaN		... with invalid signal
- *	sqrt(NaN) = NaN		... with invalid signal for signaling NaN
- *
- * Other methods : see the appended file at the end of the program below.

-Other methods  (use floating-point arithmetic)
--------------
-(This is a copy of a drafted paper by Prof W. Kahan 
-and K.C. Ng, written in May, 1986)
-
-	Two algorithms are given here to implement ieee_sqrt(x) 
-	(IEEE double precision arithmetic) in software.
-	Both supply ieee_sqrt(x) correctly rounded. The first algorithm (in
-	Section A) uses newton iterations and involves four divisions.
-	The second one uses reciproot iterations to avoid division, but
-	requires more multiplications. Both algorithms need the ability
-	to chop results of arithmetic operations instead of round them, 
-	and the INEXACT flag to indicate when an arithmetic operation
-	is executed exactly with no roundoff error, all part of the 
-	standard (IEEE 754-1985). The ability to perform shift, add,
-	subtract and logical AND operations upon 32-bit words is needed
-	too, though not part of the standard.
-
-A.  ieee_sqrt(x) by Newton Iteration
-
-   (1)	Initial approximation
-
-	Let x0 and x1 be the leading and the trailing 32-bit words of
-	a floating point number x (in IEEE double format) respectively 
-
-	    1    11		     52				  ...widths
-	   ------------------------------------------------------
-	x: |s|	  e     |	      f				|
-	   ------------------------------------------------------
-	      msb    lsb  msb				      lsb ...order
-
- 
-	     ------------------------  	     ------------------------
-	x0:  |s|   e    |    f1     |	 x1: |          f2           |
-	     ------------------------  	     ------------------------
-
-	By performing shifts and subtracts on x0 and x1 (both regarded
-	as integers), we obtain an 8-bit approximation of ieee_sqrt(x) as
-	follows.
-
-		k  := (x0>>1) + 0x1ff80000;
-		y0 := k - T1[31&(k>>15)].	... y ~ ieee_sqrt(x) to 8 bits
-	Here k is a 32-bit integer and T1[] is an integer array containing
-	correction terms. Now magically the floating value of y (y's
-	leading 32-bit word is y0, the value of its trailing word is 0)
-	approximates ieee_sqrt(x) to almost 8-bit.
-
-	Value of T1:
-	static int T1[32]= {
-	0,	1024,	3062,	5746,	9193,	13348,	18162,	23592,
-	29598,	36145,	43202,	50740,	58733,	67158,	75992,	85215,
-	83599,	71378,	60428,	50647,	41945,	34246,	27478,	21581,
-	16499,	12183,	8588,	5674,	3403,	1742,	661,	130,};
-
-    (2)	Iterative refinement
-
-	Apply Heron's rule three times to y, we have y approximates 
-	sqrt(x) to within 1 ulp (Unit in the Last Place):
-
-		y := (y+x/y)/2		... almost 17 sig. bits
-		y := (y+x/y)/2		... almost 35 sig. bits
-		y := y-(y-x/y)/2	... within 1 ulp
-
-
-	Remark 1.
-	    Another way to improve y to within 1 ulp is:
-
-		y := (y+x/y)		... almost 17 sig. bits to 2*ieee_sqrt(x)
-		y := y - 0x00100006	... almost 18 sig. bits to ieee_sqrt(x)
-
-				2
-			    (x-y )*y
-		y := y + 2* ----------	...within 1 ulp
-			       2
-			     3y  + x
-
-
-	This formula has one division fewer than the one above; however,
-	it requires more multiplications and additions. Also x must be
-	scaled in advance to avoid spurious overflow in evaluating the
-	expression 3y*y+x. Hence it is not recommended uless division
-	is slow. If division is very slow, then one should use the 
-	reciproot algorithm given in section B.
-
-    (3) Final adjustment
-
-	By twiddling y's last bit it is possible to force y to be 
-	correctly rounded according to the prevailing rounding mode
-	as follows. Let r and i be copies of the rounding mode and
-	inexact flag before entering the square root program. Also we
-	use the expression y+-ulp for the next representable floating
-	numbers (up and down) of y. Note that y+-ulp = either fixed
-	point y+-1, or multiply y by ieee_nextafter(1,+-inf) in chopped
-	mode.
-
-		I := FALSE;	... reset INEXACT flag I
-		R := RZ;	... set rounding mode to round-toward-zero
-		z := x/y;	... chopped quotient, possibly inexact
-		If(not I) then {	... if the quotient is exact
-		    if(z=y) {
-		        I := i;	 ... restore inexact flag
-		        R := r;  ... restore rounded mode
-		        return ieee_sqrt(x):=y.
-		    } else {
-			z := z - ulp;	... special rounding
-		    }
-		}
-		i := TRUE;		... ieee_sqrt(x) is inexact
-		If (r=RN) then z=z+ulp	... rounded-to-nearest
-		If (r=RP) then {	... round-toward-+inf
-		    y = y+ulp; z=z+ulp;
-		}
-		y := y+z;		... chopped sum
-		y0:=y0-0x00100000;	... y := y/2 is correctly rounded.
-	        I := i;	 		... restore inexact flag
-	        R := r;  		... restore rounded mode
-	        return ieee_sqrt(x):=y.
-		    
-    (4)	Special cases
-
-	Square root of +inf, +-0, or NaN is itself;
-	Square root of a negative number is NaN with invalid signal.
-
-
-B.  ieee_sqrt(x) by Reciproot Iteration
-
-   (1)	Initial approximation
-
-	Let x0 and x1 be the leading and the trailing 32-bit words of
-	a floating point number x (in IEEE double format) respectively
-	(see section A). By performing shifs and subtracts on x0 and y0,
-	we obtain a 7.8-bit approximation of 1/ieee_sqrt(x) as follows.
-
-	    k := 0x5fe80000 - (x0>>1);
-	    y0:= k - T2[63&(k>>14)].	... y ~ 1/ieee_sqrt(x) to 7.8 bits
-
-	Here k is a 32-bit integer and T2[] is an integer array 
-	containing correction terms. Now magically the floating
-	value of y (y's leading 32-bit word is y0, the value of
-	its trailing word y1 is set to zero) approximates 1/ieee_sqrt(x)
-	to almost 7.8-bit.
-
-	Value of T2:
-	static int T2[64]= {
-	0x1500,	0x2ef8,	0x4d67,	0x6b02,	0x87be,	0xa395,	0xbe7a,	0xd866,
-	0xf14a,	0x1091b,0x11fcd,0x13552,0x14999,0x15c98,0x16e34,0x17e5f,
-	0x18d03,0x19a01,0x1a545,0x1ae8a,0x1b5c4,0x1bb01,0x1bfde,0x1c28d,
-	0x1c2de,0x1c0db,0x1ba73,0x1b11c,0x1a4b5,0x1953d,0x18266,0x16be0,
-	0x1683e,0x179d8,0x18a4d,0x19992,0x1a789,0x1b445,0x1bf61,0x1c989,
-	0x1d16d,0x1d77b,0x1dddf,0x1e2ad,0x1e5bf,0x1e6e8,0x1e654,0x1e3cd,
-	0x1df2a,0x1d635,0x1cb16,0x1be2c,0x1ae4e,0x19bde,0x1868e,0x16e2e,
-	0x1527f,0x1334a,0x11051,0xe951,	0xbe01,	0x8e0d,	0x5924,	0x1edd,};
-
-    (2)	Iterative refinement
-
-	Apply Reciproot iteration three times to y and multiply the
-	result by x to get an approximation z that matches ieee_sqrt(x)
-	to about 1 ulp. To be exact, we will have 
-		-1ulp < ieee_sqrt(x)-z<1.0625ulp.
-	
-	... set rounding mode to Round-to-nearest
-	   y := y*(1.5-0.5*x*y*y)	... almost 15 sig. bits to 1/ieee_sqrt(x)
-	   y := y*((1.5-2^-30)+0.5*x*y*y)... about 29 sig. bits to 1/ieee_sqrt(x)
-	... special arrangement for better accuracy
-	   z := x*y			... 29 bits to ieee_sqrt(x), with z*y<1
-	   z := z + 0.5*z*(1-z*y)	... about 1 ulp to ieee_sqrt(x)
-
-	Remark 2. The constant 1.5-2^-30 is chosen to bias the error so that
-	(a) the term z*y in the final iteration is always less than 1; 
-	(b) the error in the final result is biased upward so that
-		-1 ulp < ieee_sqrt(x) - z < 1.0625 ulp
-	    instead of |ieee_sqrt(x)-z|<1.03125ulp.
-
-    (3)	Final adjustment
-
-	By twiddling y's last bit it is possible to force y to be 
-	correctly rounded according to the prevailing rounding mode
-	as follows. Let r and i be copies of the rounding mode and
-	inexact flag before entering the square root program. Also we
-	use the expression y+-ulp for the next representable floating
-	numbers (up and down) of y. Note that y+-ulp = either fixed
-	point y+-1, or multiply y by ieee_nextafter(1,+-inf) in chopped
-	mode.
-
-	R := RZ;		... set rounding mode to round-toward-zero
-	switch(r) {
-	    case RN:		... round-to-nearest
-	       if(x<= z*(z-ulp)...chopped) z = z - ulp; else
-	       if(x<= z*(z+ulp)...chopped) z = z; else z = z+ulp;
-	       break;
-	    case RZ:case RM:	... round-to-zero or round-to--inf
-	       R:=RP;		... reset rounding mod to round-to-+inf
-	       if(x<z*z ... rounded up) z = z - ulp; else
-	       if(x>=(z+ulp)*(z+ulp) ...rounded up) z = z+ulp;
-	       break;
-	    case RP:		... round-to-+inf
-	       if(x>(z+ulp)*(z+ulp)...chopped) z = z+2*ulp; else
-	       if(x>z*z ...chopped) z = z+ulp;
-	       break;
-	}
-
-	Remark 3. The above comparisons can be done in fixed point. For
-	example, to compare x and w=z*z chopped, it suffices to compare
-	x1 and w1 (the trailing parts of x and w), regarding them as
-	two's complement integers.
-
-	...Is z an exact square root?
-	To determine whether z is an exact square root of x, let z1 be the
-	trailing part of z, and also let x0 and x1 be the leading and
-	trailing parts of x.
-
-	If ((z1&0x03ffffff)!=0)	... not exact if trailing 26 bits of z!=0
-	    I := 1;		... Raise Inexact flag: z is not exact
-	else {
-	    j := 1 - [(x0>>20)&1]	... j = ieee_logb(x) mod 2
-	    k := z1 >> 26;		... get z's 25-th and 26-th 
-					    fraction bits
-	    I := i or (k&j) or ((k&(j+j+1))!=(x1&3));
-	}
-	R:= r		... restore rounded mode
-	return ieee_sqrt(x):=z.
-
-	If multiplication is cheaper then the foregoing red tape, the 
-	Inexact flag can be evaluated by
-
-	    I := i;
-	    I := (z*z!=x) or I.
-
-	Note that z*z can overwrite I; this value must be sensed if it is 
-	True.
-
-	Remark 4. If z*z = x exactly, then bit 25 to bit 0 of z1 must be
-	zero.
-
-		    --------------------
-		z1: |        f2        | 
-		    --------------------
-		bit 31		   bit 0
-
-	Further more, bit 27 and 26 of z1, bit 0 and 1 of x1, and the odd
-	or even of ieee_logb(x) have the following relations:
-
-	-------------------------------------------------
-	bit 27,26 of z1		bit 1,0 of x1	logb(x)

- * __kernel_cos( x,  y )
- * kernel cos function on [-pi/4, pi/4], pi/4 ~ 0.785398164
- * Input x is assumed to be bounded by ~pi/4 in magnitude.
- * Input y is the tail of x. 
- *
- * Algorithm
- *	1. Since ieee_cos(-x) = ieee_cos(x), we need only to consider positive x.
- *	2. if x < 2^-27 (hx<0x3e400000 0), return 1 with inexact if x!=0.
- *	3. ieee_cos(x) is approximated by a polynomial of degree 14 on
- *	   [0,pi/4]
- *		  	                 4            14
- *	   	cos(x) ~ 1 - x*x/2 + C1*x + ... + C6*x
- *	   where the remez error is
- *	
- * 	|              2     4     6     8     10    12     14 |     -58
- * 	|ieee_cos(x)-(1-.5*x +C1*x +C2*x +C3*x +C4*x +C5*x  +C6*x  )| <= 2
- * 	|    					               | 
- * 
- * 	               4     6     8     10    12     14 
- *	4. let r = C1*x +C2*x +C3*x +C4*x +C5*x  +C6*x  , then
- *	       ieee_cos(x) = 1 - x*x/2 + r
- *	   since ieee_cos(x+y) ~ ieee_cos(x) - ieee_sin(x)*y 
- *			  ~ ieee_cos(x) - x*y,
- *	   a correction term is necessary in ieee_cos(x) and hence
- *		cos(x+y) = 1 - (x*x/2 - (r - x*y))
- *	   For better accuracy when x > 0.3, let qx = |x|/4 with
- *	   the last 32 bits mask off, and if x > 0.78125, let qx = 0.28125.
- *	   Then
- *		cos(x+y) = (1-qx) - ((x*x/2-qx) - (r-x*y)).
- *	   Note that 1-qx and (x*x/2-qx) is EXACT here, and the
- *	   magnitude of the latter is at least a quarter of x*x/2,
- *	   thus, reducing the rounding error in the subtraction.

- * 
- * __kernel_rem_pio2 return the last three digits of N with 
- *		y = x - N*pi/2
- * so that |y| < pi/2.
- *
- * The method is to compute the integer (mod 8) and fraction parts of 
- * (2/pi)*x without doing the full multiplication. In general we
- * skip the part of the product that are known to be a huge integer (
- * more accurately, = 0 mod 8 ). Thus the number of operations are
- * independent of the exponent of the input.
- *
- * (2/pi) is represented by an array of 24-bit integers in ipio2[].
- *
- * Input parameters:
- * 	x[]	The input value (must be positive) is broken into nx 
- *		pieces of 24-bit integers in double precision format.
- *		x[i] will be the i-th 24 bit of x. The scaled exponent 
- *		of x[0] is given in input parameter e0 (i.e., x[0]*2^e0 
- *		match x's up to 24 bits.
- *
- *		Example of breaking a double positive z into x[0]+x[1]+x[2]:
- *			e0 = ieee_ilogb(z)-23
- *			z  = ieee_scalbn(z,-e0)
- *		for i = 0,1,2
- *			x[i] = ieee_floor(z)
- *			z    = (z-x[i])*2**24
- *
- *
- *	y[]	ouput result in an array of double precision numbers.
- *		The dimension of y[] is:
- *			24-bit  precision	1
- *			53-bit  precision	2
- *			64-bit  precision	2
- *			113-bit precision	3
- *		The actual value is the sum of them. Thus for 113-bit
- *		precison, one may have to do something like:
- *
- *		long double t,w,r_head, r_tail;
- *		t = (long double)y[2] + (long double)y[1];
- *		w = (long double)y[0];
- *		r_head = t+w;
- *		r_tail = w - (r_head - t);
- *
- *	e0	The exponent of x[0]
- *
- *	nx	dimension of x[]
- *
- *  	prec	an integer indicating the precision:
- *			0	24  bits (single)
- *			1	53  bits (double)
- *			2	64  bits (extended)
- *			3	113 bits (quad)
- *
- *	ipio2[]
- *		integer array, contains the (24*i)-th to (24*i+23)-th 
- *		bit of 2/pi after binary point. The corresponding 
- *		floating value is
- *
- *			ipio2[i] * 2^(-24(i+1)).
- *
- * External function:
- *	double ieee_scalbn(), ieee_floor();
- *
- *
- * Here is the description of some local variables:
- *
- * 	jk	jk+1 is the initial number of terms of ipio2[] needed
- *		in the computation. The recommended value is 2,3,4,
- *		6 for single, double, extended,and quad.
- *
- * 	jz	local integer variable indicating the number of 
- *		terms of ipio2[] used. 
- *
- *	jx	nx - 1
- *
- *	jv	index for pointing to the suitable ipio2[] for the
- *		computation. In general, we want
- *			( 2^e0*x[0] * ipio2[jv-1]*2^(-24jv) )/8
- *		is an integer. Thus
- *			e0-3-24*jv >= 0 or (e0-3)/24 >= jv
- *		Hence jv = max(0,(e0-3)/24).
- *
- *	jp	jp+1 is the number of terms in PIo2[] needed, jp = jk.
- *
- * 	q[]	double array with integral value, representing the
- *		24-bits chunk of the product of x and 2/pi.
- *
- *	q0	the corresponding exponent of q[0]. Note that the
- *		exponent for q[i] would be q0-24*i.
- *
- *	PIo2[]	double precision array, obtained by cutting pi/2
- *		into 24 bits chunks. 
- *
- *	f[]	ipio2[] in floating point 
- *
- *	iq[]	integer array by breaking up q[] in 24-bits chunk.
- *
- *	fq[]	final product of x*(2/pi) in fq[0],..,fq[jk]
- *
- *	ih	integer. If >0 it indicates q[] is >= 0.5, hence
- *		it also indicates the *sign* of the result.

-/* __kernel_tan( x, y, k )
- * kernel tan function on [-pi/4, pi/4], pi/4 ~ 0.7854
- * Input x is assumed to be bounded by ~pi/4 in magnitude.
- * Input y is the tail of x.
- * Input k indicates whether ieee_tan (if k = 1) or -1/tan (if k = -1) is returned.
- *
- * Algorithm
- *	1. Since ieee_tan(-x) = -ieee_tan(x), we need only to consider positive x.
- *	2. if x < 2^-28 (hx<0x3e300000 0), return x with inexact if x!=0.
- *	3. ieee_tan(x) is approximated by a odd polynomial of degree 27 on
- *	   [0,0.67434]
- *		  	         3             27
- *	   	tan(x) ~ x + T1*x + ... + T13*x
- *	   where
- *
- * 	        |ieee_tan(x)         2     4            26   |     -59.2
- * 	        |----- - (1+T1*x +T2*x +.... +T13*x    )| <= 2
- * 	        |  x 					|
- *
- *	   Note: ieee_tan(x+y) = ieee_tan(x) + tan'(x)*y
- *		          ~ ieee_tan(x) + (1+x*x)*y
- *	   Therefore, for better accuracy in computing ieee_tan(x+y), let
- *		     3      2      2       2       2
- *		r = x *(T2+x *(T3+x *(...+x *(T12+x *T13))))
- *	   then
- *		 		    3    2
- *		tan(x+y) = x + (T1*x + (x *(r+y)+y))
- *
- *      4. For x in [0.67434,pi/4],  let y = pi/4 - x, then
- *		tan(x) = ieee_tan(pi/4-y) = (1-ieee_tan(y))/(1+ieee_tan(y))
- *		       = 1 - 2*(ieee_tan(y) - (ieee_tan(y)^2)/(1+ieee_tan(y)))

-	  *********************************
- 	  * Announcing FDLIBM Version 5.3 *
-	  *********************************
-============================================================
-			FDLIBM
-============================================================
-	developed at Sun Microsystems, Inc. 
-
-What's new in FDLIBM 5.3?
-
-CONFIGURE
-	To build FDLIBM, edit the supplied Makefile or create
-	a local Makefile by running "sh configure" 
-	using the supplied configure script contributed by Nelson Beebe
-
-BUGS FIXED
-
-    1. e_pow.c incorrect results when 
-	x is very close to -1.0 and y is very large, e.g.
-  	pow(-1.0000000000000002e+00,4.5035996273704970e+15) = 0
-  	pow(-9.9999999999999978e-01,4.5035996273704970e+15) = 0
-	Correct results are close to -e and -1/e.
-
-    2. k_tan.c error was > 1 ulp target for FDLIBM
-	5.2: Worst error at least 1.45 ulp at
-	tan(1.7765241907548024E+269) = 1.7733884462610958E+16
-	5.3: Worst error 0.96 ulp
-
-NOT FIXED YET
-
-    3. Compiler failure on non-standard code
-	Statements like
-	            *(1+(int*)&t1) = 0;
-	are not standard C and cause some optimizing compilers (e.g. GCC)
-	to generate bad code under optimization.    These cases
-	are to be addressed in the next release.
-	
-FDLIBM (Freely Distributable LIBM) is a C math library 
-for machines that support IEEE 754 floating-point arithmetic. 
-In this release, only double precision is supported.
-
-FDLIBM is intended to provide a reasonably portable (see 
-assumptions below), reference quality (below one ulp for
-major functions like sin,cos,exp,log) math library 
-(libm.a).  For a copy of FDLIBM, please see
-	http://www.netlib.org/fdlibm/
-or
-	http://www.validlab.com/software/
-
---------------
-1. ASSUMPTIONS
---------------
-FDLIBM (double precision version) assumes:
- a.  IEEE 754 style (if not precise compliance) arithmetic;
- b.  32 bit 2's complement integer arithmetic;
- c.  Each double precision floating-point number must be in IEEE 754 
-     double format, and that each number can be retrieved as two 32-bit 
-     integers through the using of pointer bashing as in the example 
-     below:
-
-     Example: let y = 2.0
-	double fp number y: 	2.0
-	IEEE double format:	0x4000000000000000
-
-	Referencing y as two integers:
-	*(int*)&y,*(1+(int*)&y) =	{0x40000000,0x0} (on sparc)
-					{0x0,0x40000000} (on 386)
-
-	Note: Four macros are defined in fdlibm.h to handle this kind of
-	retrieving:
-
-	__HI(x)		the high part of a double x 
-			(sign,exponent,the first 21 significant bits)
-	__LO(x)		the least 32 significant bits of x
-	__HIp(x)	same as __HI except that the argument is a pointer
-			to a double
-	__LOp(x)	same as __LO except that the argument is a pointer
-			to a double
-	
-	To ensure obtaining correct ordering, one must define  __LITTLE_ENDIAN
-	during compilation for little endian machine (like 386,486). The 
-	default is big endian.
-
-	If the behavior of pointer bashing is undefined, one may hack on the 
-	macro in fdlibm.h.
-	
-  d. IEEE exceptions may trigger "signals" as is common in Unix
-     implementations. 
-
--------------------
-2. EXCEPTION CASES
--------------------
-All exception cases in the FDLIBM functions will be mapped
-to one of the following four exceptions:
-
-   +-huge*huge, +-tiny*tiny,    +-1.0/0.0,	+-0.0/0.0
-    (overflow)	(underflow)  (divided-by-zero) 	(invalid)
-
-For example, ieee_log(0) is a singularity and is thus mapped to 
-	-1.0/0.0 = -infinity.
-That is, FDLIBM's log will compute -one/zero and return the
-computed value.  On an IEEE machine, this will trigger the 
-divided-by-zero exception and a negative infinity is returned by 
-default.
-
-Similarly, ieee_exp(-huge) will be mapped to tiny*tiny to generate
-an underflow signal. 
-
-
---------------------------------
-3. STANDARD CONFORMANCE WRAPPER 
---------------------------------
-The default FDLIBM functions (compiled with -D_IEEE_LIBM flag)  
-are in "IEEE spirit" (i.e., return the most reasonable result in 
-floating-point arithmetic). If one wants FDLIBM to comply with
-standards like SVID, X/OPEN, or POSIX/ANSI, then one can 
-create a multi-standard compliant FDLIBM. In this case, each
-function in FDLIBM is actually a standard compliant wrapper
-function.  
-
-File organization:
-    1. For FDLIBM's kernel (internal) function,
-		File name	Entry point
-		---------------------------
-		k_sin.c		__kernel_sin
-		k_tan.c		__kernel_tan
-		---------------------------
-    2. For functions that have no standards conflict 
-		File name	Entry point
-		---------------------------
-		s_sin.c		sin
-		s_erf.c		erf
-		---------------------------
-    3. Ieee754 core functions
-		File name	Entry point
-		---------------------------
-		e_exp.c		__ieee754_exp
-		e_sinh.c	__ieee754_sinh
-		---------------------------
-    4. Wrapper functions
-		File name	Entry point
-		---------------------------
-		w_exp.c		exp
-		w_sinh.c	sinh
-		---------------------------
-
-Wrapper functions will twist the result of the ieee754 
-function to comply to the standard specified by the value 
-of _LIB_VERSION 
-    if _LIB_VERSION = _IEEE_, return the ieee754 result;
-    if _LIB_VERSION = _SVID_, return SVID result;
-    if _LIB_VERSION = _XOPEN_, return XOPEN result;
-    if _LIB_VERSION = _POSIX_, return POSIX/ANSI result.
-(These are macros, see fdlibm.h for their definition.)
-
-
---------------------------------
-4. HOW TO CREATE FDLIBM's libm.a
---------------------------------
-There are two types of libm.a. One is IEEE only, and the other is
-multi-standard compliant (supports IEEE,XOPEN,POSIX/ANSI,SVID).
-
-To create the IEEE only libm.a, use 
-	    make "CFLAGS = -D_IEEE_LIBM"	 
-This will create an IEEE libm.a, which is smaller in size, and 
-somewhat faster.
-
-To create a multi-standard compliant libm, use
-    make "CFLAGS = -D_IEEE_MODE"   --- multi-standard fdlibm: default
-					 to IEEE
-    make "CFLAGS = -D_XOPEN_MODE"  --- multi-standard fdlibm: default
-					 to X/OPEN
-    make "CFLAGS = -D_POSIX_MODE"  --- multi-standard fdlibm: default
-					 to POSIX/ANSI
-    make "CFLAGS = -D_SVID3_MODE"  --- multi-standard fdlibm: default
-					 to SVID
-
-
-Here is how one makes a SVID compliant libm.
-    Make the library by
-		make "CFLAGS = -D_SVID3_MODE".
-    The libm.a of FDLIBM will be multi-standard compliant and 
-    _LIB_VERSION is initialized to the value _SVID_ . 
-
-    example1:
-    ---------
-	    main()
-	    {
-		double ieee_y0();
-		printf("y0(1e300) = %1.20e\n",y0(1e300));
-		exit(0);
-	    }
-
-    % cc example1.c libm.a
-    % a.out
-    y0: TLOSS error
-    ieee_y0(1e300) = 0.00000000000000000000e+00
-
-
-It is possible to change the default standard in multi-standard 
-fdlibm. Here is an example of how to do it:
-    example2:
-    ---------
-	#include "fdlibm.h"	/* must include FDLIBM's fdlibm.h */
-	main()
-	{
-		double ieee_y0();
-		_LIB_VERSION =  _IEEE_;
-		printf("IEEE: ieee_y0(1e300) = %1.20e\n",y0(1e300));
-		_LIB_VERSION = _XOPEN_;
-		printf("XOPEN ieee_y0(1e300) = %1.20e\n",y0(1e300));
-		_LIB_VERSION = _POSIX_;
-		printf("POSIX ieee_y0(1e300) = %1.20e\n",y0(1e300));
-		_LIB_VERSION = _SVID_;
-		printf("SVID  ieee_y0(1e300) = %1.20e\n",y0(1e300));
-		exit(0);
-	}
-
-    % cc example2.c libm.a
-    % a.out
-      IEEE: ieee_y0(1e300) = -1.36813604503424810557e-151
-      XOPEN ieee_y0(1e300) = 0.00000000000000000000e+00
-      POSIX ieee_y0(1e300) = 0.00000000000000000000e+00
-      y0: TLOSS error
-      SVID  ieee_y0(1e300) = 0.00000000000000000000e+00
-
-Note:	Here _LIB_VERSION is a global variable. If global variables 
-	are forbidden, then one should modify fdlibm.h to change
-	_LIB_VERSION to be a global constant. In this case, one
-	may not change the value of _LIB_VERSION as in example2.
-
----------------------------
-5. NOTES ON PORTING FDLIBM
----------------------------
-	Care must be taken when installing FDLIBM over existing
-	libm.a.
-	All co-existing function prototypes must agree, otherwise
-	users will encounter mysterious failures.
-
-	So far, the only known likely conflict is the declaration 
-	of the IEEE recommended function scalb:
-
-		double ieee_scalb(double,double)	(1)	SVID3 defined
-		double ieee_scalb(double,int)	(2)	IBM,DEC,...
-
-	FDLIBM follows Sun definition and use (1) as default. 
-	If one's existing libm.a uses (2), then one may raise
-	the flags _SCALB_INT during the compilation of FDLIBM
-	to get the correct function prototype.
-	(E.g., make "CFLAGS = -D_IEEE_LIBM -D_SCALB_INT".)
-	NOTE that if -D_SCALB_INT is raised, it won't be SVID3
-	conformant.

- *         	erf(x)  = sign(x)*(1.0 - tiny)
- *	   where
- *		R2(z) = degree 6 poly in z, (z=1/x^2)
- *		S2(z) = degree 7 poly in z
- *
- *      Note1:
- *	   To compute ieee_exp(-x*x-0.5625+R/S), let s be a single
- *	   precision number and s := x; then
- *		-x*x = -s*s + (s-x)*(s+x)
- *	        ieee_exp(-x*x-0.5626+R/S) = 
- *			exp(-s*s-0.5625)*ieee_exp((s-x)*(s+x)+R/S);
- *      Note2:
- *	   Here 4 and 5 make use of the asymptotic series
- *			  ieee_exp(-x*x)
- *		erfc(x) ~ ---------- * ( 1 + Poly(1/x^2) )
- *			  x*ieee_sqrt(pi)
- *	   We use rational approximation to approximate
- *      	g(s)=f(1/x^2) = ieee_log(ieee_erfc(x)*x) - x*x + 0.5625
- *	   Here is the error bound for R1/S1 and R2/S2
- *      	|R1/S1 - f(x)|  < 2**(-62.57)
- *      	|R2/S2 - f(x)|  < 2**(-61.52)
- *
- *      5. For inf > x >= 28
- *         	erf(x)  = sign(x) *(1 - tiny)  (raise inexact)
- *         	erfc(x) = tiny*tiny (raise underflow) if x > 0
- *			= 2 - tiny if x<0
- *
- *      7. Special case:
- *         	erf(0)  = 0, ieee_erf(inf)  = 1, ieee_erf(-inf) = -1,
- *         	erfc(0) = 1, ieee_erfc(inf) = 0, ieee_erfc(-inf) = 2, 
- *	   	erfc/ieee_erf(NaN) is NaN

-/* ieee_expm1(x)
- * Returns ieee_exp(x)-1, the exponential of x minus 1.
- *
- * Method
- *   1. Argument reduction:
- *	Given x, find r and integer k such that
- *
- *               x = k*ln2 + r,  |r| <= 0.5*ln2 ~ 0.34658  
- *
- *      Here a correction term c will be computed to compensate 
- *	the error in r when rounded to a floating-point number.
- *
- *   2. Approximating ieee_expm1(r) by a special rational function on
- *	the interval [0,0.34658]:
- *	Since
- *	    r*(ieee_exp(r)+1)/(ieee_exp(r)-1) = 2+ r^2/6 - r^4/360 + ...
- *	we define R1(r*r) by
- *	    r*(ieee_exp(r)+1)/(ieee_exp(r)-1) = 2+ r^2/6 * R1(r*r)
- *	That is,
- *	    R1(r**2) = 6/r *((ieee_exp(r)+1)/(ieee_exp(r)-1) - 2/r)
- *		     = 6/r * ( 1 + 2.0*(1/(ieee_exp(r)-1) - 1/r))
- *		     = 1 - r^2/60 + r^4/2520 - r^6/100800 + ...
- *      We use a special Remes algorithm on [0,0.347] to generate 
- * 	a polynomial of degree 5 in r*r to approximate R1. The 
- *	maximum error of this polynomial approximation is bounded 
- *	by 2**-61. In other words,
- *	    R1(z) ~ 1.0 + Q1*z + Q2*z**2 + Q3*z**3 + Q4*z**4 + Q5*z**5
- *	where 	Q1  =  -1.6666666666666567384E-2,
- * 		Q2  =   3.9682539681370365873E-4,
- * 		Q3  =  -9.9206344733435987357E-6,
- * 		Q4  =   2.5051361420808517002E-7,
- * 		Q5  =  -6.2843505682382617102E-9;
- *  	(where z=r*r, and the values of Q1 to Q5 are listed below)
- *	with error bounded by
- *	    |                  5           |     -61
- *	    | 1.0+Q1*z+...+Q5*z   -  R1(z) | <= 2 
- *	    |                              |
- *	
- *	expm1(r) = ieee_exp(r)-1 is then computed by the following 
- * 	specific way which minimize the accumulation rounding error: 
- *			       2     3
- *			      r     r    [ 3 - (R1 + R1*r/2)  ]
- *	      ieee_expm1(r) = r + --- + --- * [--------------------]
- *		              2     2    [ 6 - r*(3 - R1*r/2) ]
- *	
- *	To compensate the error in the argument reduction, we use
- *		expm1(r+c) = ieee_expm1(r) + c + ieee_expm1(r)*c 
- *			   ~ ieee_expm1(r) + c + r*c 
- *	Thus c+r*c will be added in as the correction terms for
- *	expm1(r+c). Now rearrange the term to avoid optimization 
- * 	screw up:
- *		        (      2                                    2 )
- *		        ({  ( r    [ R1 -  (3 - R1*r/2) ]  )  }    r  )
- *	 ieee_expm1(r+c)~r - ({r*(--- * [--------------------]-c)-c} - --- )
- *	                ({  ( 2    [ 6 - r*(3 - R1*r/2) ]  )  }    2  )
- *                      (                                             )
- *    	
- *		   = r - E
- *   3. Scale back to obtain ieee_expm1(x):
- *	From step 1, we have
- *	   ieee_expm1(x) = either 2^k*[expm1(r)+1] - 1
- *		    = or     2^k*[expm1(r) + (1-2^-k)]
- *   4. Implementation notes:
- *	(A). To save one multiplication, we scale the coefficient Qi
- *	     to Qi*2^i, and replace z by (x^2)/2.
- *	(B). To achieve maximum accuracy, we compute ieee_expm1(x) by
- *	  (i)   if x < -56*ln2, return -1.0, (raise inexact if x!=inf)
- *	  (ii)  if k=0, return r-E
- *	  (iii) if k=-1, return 0.5*(r-E)-0.5
- *        (iv)	if k=1 if r < -0.25, return 2*((r+0.5)- E)
- *	       	       else	     return  1.0+2.0*(r-E);
- *	  (v)   if (k<-2||k>56) return 2^k(1-(E-r)) - 1 (or ieee_exp(x)-1)
- *	  (vi)  if k <= 20, return 2^k((1-2^-k)-(E-r)), else
- *	  (vii) return 2^k(1-((E+2^-k)-r)) 
- *
- * Special cases:
- *	expm1(INF) is INF, ieee_expm1(NaN) is NaN;
- *	expm1(-INF) is -1, and
- *	for finite argument, only ieee_expm1(0)=0 is exact.
- *
- * Accuracy:
- *	according to an error analysis, the error is always less than
- *	1 ulp (unit in the last place).
- *
- * Misc. info.
- *	For IEEE double 
- *	    if x >  7.09782712893383973096e+02 then ieee_expm1(x) overflow
- *
- * Constants:
- * The hexadecimal values are the intended ones for the following 
- * constants. The decimal values may be used, provided that the 
- * compiler will convert from decimal to binary accurately enough
- * to produce the hexadecimal values shown.

- *	term is need. Let u=1+x rounded. Let c = (1+x)-u, then
- *	log(1+x) - ieee_log(u) ~ c/u. Thus, we proceed to compute ieee_log(u),
- *	and add back the correction term c/u.
- *	(Note: when x > 2**53, one can simply return ieee_log(x))
- *
- *   2. Approximation of ieee_log1p(f).
- *	Let s = f/(2+f) ; based on ieee_log(1+f) = ieee_log(1+s) - ieee_log(1-s)
- *		 = 2s + 2/3 s**3 + 2/5 s**5 + .....,
- *	     	 = 2s + s*R
- *      We use a special Reme algorithm on [0,0.1716] to generate 
- * 	a polynomial of degree 14 to approximate R The maximum error 
- *	of this polynomial approximation is bounded by 2**-58.45. In
- *	other words,
- *		        2      4      6      8      10      12      14
- *	    R(z) ~ Lp1*s +Lp2*s +Lp3*s +Lp4*s +Lp5*s  +Lp6*s  +Lp7*s
- *  	(the values of Lp1 to Lp7 are listed in the program)
- *	and
- *	    |      2          14          |     -58.45
- *	    | Lp1*s +...+Lp7*s    -  R(z) | <= 2 
- *	    |                             |
- *	Note that 2s = f - s*f = f - hfsq + s*hfsq, where hfsq = f*f/2.
- *	In order to guarantee error in log below 1ulp, we compute log
- *	by
- *		log1p(f) = f - (hfsq - s*(hfsq+R)).
- *	
- *	3. Finally, ieee_log1p(x) = k*ln2 + ieee_log1p(f).  
- *		 	     = k*ln2_hi+(f-(hfsq-(s*(hfsq+R)+k*ln2_lo)))
- *	   Here ln2 is split into two floating point number: 
- *			ln2_hi + ln2_lo,
- *	   where n*ln2_hi is always exact for |n| < 2000.
- *
- * Special cases:
- *	log1p(x) is NaN with signal if x < -1 (including -INF) ; 
- *	log1p(+INF) is +INF; ieee_log1p(-1) is -INF with signal;
- *	log1p(NaN) is that NaN with no signal.
- *
- * Accuracy:
- *	according to an error analysis, the error is always less than
- *	1 ulp (unit in the last place).
- *
- * Constants:
- * The hexadecimal values are the intended ones for the following 
- * constants. The decimal values may be used, provided that the 
- * compiler will convert from decimal to binary accurately enough 
- * to produce the hexadecimal values shown.
- *
- * Note: Assuming ieee_log() return accurate answer, the following
- * 	 algorithm can be used to compute ieee_log1p(x) to within a few ULP:
- *	
- *		u = 1+x;
- *		if(u==1.0) return x ; else
- *			   return ieee_log(u)*(x/(u-1.0));
- *
