- *
- * Method :
- *	Based on 
- *		acosh(x) = log [ x + sqrt(x*x-1) ]
- *	we have
- *		acosh(x) := log1p(x)+ln2,	if (x > 1.0E20); else

- *	These formulae avoid the over/underflow complication.
- *
- * Special cases:
- *	acosh(x) is NaN with signal if x<1.
- *	acosh(NaN) is NaN without signal.
- *
- * Accuracy:
- *	acosh(x) returns the exact inverse hyperbolic cosine of x nearly 
- *	rounded. In a test run with 512,000 random arguments on a VAX, the

-/* ATAN2(Y,X)
- * RETURN ARG (X+iY)
- * DOUBLE PRECISION (VAX D format 56 bits, IEEE DOUBLE 53 BITS)
- * CODED IN C BY K.C. NG, 1/8/85; 
- * REVISED BY K.C. NG on 2/7/85, 2/13/85, 3/7/85, 3/30/85, 6/29/85.
- *
- * Required system supported functions :
- *	copysign(x,y)
- *	scalb(x,y)
- *	logb(x)
- *	
- * Method :
- *	1. Reduce y to positive by atan2(y,x)=-atan2(-y,x).
- *	2. Reduce x to positive by (if x and y are unexceptional): 
- *		ARG (x+iy) = arctan(y/x)   	   ... if x > 0,
- *		ARG (x+iy) = pi - arctan[y/(-x)]   ... if x < 0,
- *	3. According to the integer k=4t+0.25 truncated , t=y/x, the argument 
- *	   is further reduced to one of the following intervals and the 
- *	   arctangent of y/x is evaluated by the corresponding formula:
- *
- *         [0,7/16]	   atan(y/x) = t - t^3*(a1+t^2*(a2+...(a10+t^2*a11)...)
- *	   [7/16,11/16]    atan(y/x) = atan(1/2) + atan( (y-x/2)/(x+y/2) )
- *	   [11/16.19/16]   atan(y/x) = atan( 1 ) + atan( (y-x)/(x+y) )
- *	   [19/16,39/16]   atan(y/x) = atan(3/2) + atan( (y-1.5x)/(x+1.5y) )
- *	   [39/16,INF]     atan(y/x) = atan(INF) + atan( -x/y )
- *
- * Special cases:
- * Notations: atan2(y,x) == ARG (x+iy) == ARG(x,y).
- *
- *	ARG( NAN , (anything) ) is NaN;
- *	ARG( (anything), NaN ) is NaN;
- *	ARG(+(anything but NaN), +-0) is +-0  ;
- *	ARG(-(anything but NaN), +-0) is +-PI ;
- *	ARG( 0, +-(anything but 0 and NaN) ) is +-PI/2;
- *	ARG( +INF,+-(anything but INF and NaN) ) is +-0 ;
- *	ARG( -INF,+-(anything but INF and NaN) ) is +-PI;
- *	ARG( +INF,+-INF ) is +-PI/4 ;
- *	ARG( -INF,+-INF ) is +-3PI/4;
- *	ARG( (anything but,0,NaN, and INF),+-INF ) is +-PI/2;
- *
- * Accuracy:
- *	atan2(y,x) returns (PI/pi) * the exact ARG (x+iy) nearly rounded, 
- *	where
- *
- *	in decimal:
- *		pi = 3.141592653589793 23846264338327 ..... 
- *    53 bits   PI = 3.141592653589793 115997963 ..... ,
- *    56 bits   PI = 3.141592653589793 227020265 ..... ,  
- *
- *	in hexadecimal:
- *		pi = 3.243F6A8885A308D313198A2E....
- *    53 bits   PI = 3.243F6A8885A30  =  2 * 1.921FB54442D18	error=.276ulps
- *    56 bits   PI = 3.243F6A8885A308 =  4 * .C90FDAA22168C2    error=.206ulps
- *	
- *	In a test run with 356,000 random argument on [-1,1] * [-1,1] on a
- *	VAX, the maximum observed error was 1.41 ulps (units of the last place)
- *	compared with (PI/pi)*(the exact ARG(x+iy)).
- *
- * Note:
- *	We use machine PI (the true pi rounded) in place of the actual
- *	value of pi for all the trig and inverse trig functions. In general, 
- *	if trig is one of sin, cos, tan, then computed trig(y) returns the 
- *	exact trig(y*pi/PI) nearly rounded; correspondingly, computed arctrig 
- *	returns the exact arctrig(y)*PI/pi nearly rounded. These guarantee the 
- *	trig functions have period PI, and trig(arctrig(x)) returns x for
- *	all critical values x.
- *	
- * 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.

-/* EXPM1(X)
- * RETURN THE EXPONENTIAL OF X MINUS ONE
- * DOUBLE PRECISION (IEEE 53 BITS, VAX D FORMAT 56 BITS)
- * CODED IN C BY K.C. NG, 1/19/85; 
- * REVISED BY K.C. NG on 2/6/85, 3/7/85, 3/21/85, 4/16/85.
- *
- * Required system supported functions:
- *	scalb(x,n)	
- *	copysign(x,y)	
- *	finite(x)
- *
- * Kernel function:
- *	exp__E(x,c)
- *
- * Method:
- *	1. Argument Reduction: given the input x, find r and integer k such 
- *	   that
- *	                   x = k*ln2 + r,  |r| <= 0.5*ln2 .  
- *	   r will be represented as r := z+c for better accuracy.
- *
- *	2. Compute EXPM1(r)=exp(r)-1 by 
- *
- *			EXPM1(r=z+c) := z + exp__E(z,c)
- *
- *	3. EXPM1(x) =  2^k * ( EXPM1(r) + 1-2^-k ).
- *
- * 	Remarks: 
- *	   1. When k=1 and z < -0.25, we use the following formula for
- *	      better accuracy:
- *			EXPM1(x) = 2 * ( (z+0.5) + exp__E(z,c) )
- *	   2. To avoid rounding error in 1-2^-k where k is large, we use
- *			EXPM1(x) = 2^k * { [z+(exp__E(z,c)-2^-k )] + 1 }
- *	      when k>56. 
- *
- * Special cases:
- *	EXPM1(INF) is INF, EXPM1(NaN) is NaN;
- *	EXPM1(-INF)= -1;
- *	for finite argument, only EXPM1(0)=0 is exact.
- *
- * Accuracy:
- *	EXPM1(x) returns the exact (exp(x)-1) nearly rounded. In a test run with
- *	1,166,000 random arguments on a VAX, the maximum observed error was
- *	.872 ulps (units of 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.

- *    The fmod function computes the floating-point remainder of x/y.
- *
- * RETURNS
- *
- *    The fmod function returns the value x-i*y, for some integer i
- * such that, if y is nonzero, the result has the same sign as x and
- * magnitude less than the magnitude of y.
- *
- * On a VAX or CCI,
- *
- *    fmod(x,0) traps/faults on floating-point divided-by-zero.
- *
- * On IEEE-754 conforming machines with "isnan()" primitive,
- *
- *    fmod(x,0), fmod(INF,y) are invalid operations and NaN is returned.

-/* Table-driven natural logarithm.
- *
- * This code was derived, with minor modifications, from:
- *	Peter Tang, "Table-Driven Implementation of the
- *	Logarithm in IEEE Floating-Point arithmetic." ACM Trans.
- *	Math Software, vol 16. no 4, pp 378-400, Dec 1990).
- *
- * Calculates log(2^m*F*(1+f/F)), |f/j| <= 1/256,
- * where F = j/128 for j an integer in [0, 128].
- *
- * log(2^m) = log2_hi*m + log2_tail*m
- * since m is an integer, the dominant term is exact.
- * m has at most 10 digits (for subnormal numbers),
- * and log2_hi has 11 trailing zero bits.
- *
- * log(F) = logF_hi[j] + logF_lo[j] is in tabular form in log_table.h
- * logF_hi[] + 512 is exact.
- *
- * log(1+f/F) = 2*f/(2*F + f) + 1/12 * (2*f/(2*F + f))**3 + ...
- * the leading term is calculated to extra precision in two
- * parts, the larger of which adds exactly to the dominant
- * m and F terms.
- * There are two cases:
- *	1. when m, j are non-zero (m | j), use absolute
- *	   precision for the leading term.
- *	2. when m = j = 0, |1-x| < 1/256, and log(x) ~= (x-1).
- *	   In this case, use a relative precision of 24 bits.
- * (This is done differently in the original paper)
- *
- * Special cases:
- *	0	return signalling -Inf
- *	neg	return signalling NaN
- *	+Inf	return +Inf

- * RETURN THE LOGARITHM OF 1+x
- * DOUBLE PRECISION (VAX D FORMAT 56 bits, IEEE DOUBLE 53 BITS)
- * CODED IN C BY K.C. NG, 1/19/85; 
- * REVISED BY K.C. NG on 2/6/85, 3/7/85, 3/24/85, 4/16/85.
- * 
- * Required system supported functions:
- *	scalb(x,n) 
- *	copysign(x,y)
- *	logb(x)	
- *	finite(x)
- *
- * Required kernel function:
- *	log__L(z)
- *
- * Method :
- *	1. Argument Reduction: find k and f such that 
- *			1+x  = 2^k * (1+f), 
- *	   where  sqrt(2)/2 < 1+f < sqrt(2) .
- *
- *	2. Let s = f/(2+f) ; based on log(1+f) = log(1+s) - log(1-s)
- *		 = 2s + 2/3 s**3 + 2/5 s**5 + .....,
- *	   log(1+f) is computed by
- *
- *	     		log(1+f) = 2s + s*log__L(s*s)
- *	   where
- *		log__L(z) = z*(L1 + z*(L2 + z*(... (L6 + z*L7)...)))
- *
- *	   See log__L() for the values of the coefficients.
- *
- *	3. Finally,  log(1+x) = k*ln2 + log(1+f).  
- *
- *	Remarks 1. In step 3 n*ln2 will be stored in two floating point numbers
- *		   n*ln2hi + n*ln2lo, where ln2hi is chosen such that the last 
- *		   20 bits (for VAX D format), or the last 21 bits ( for IEEE 
- *		   double) is 0. This ensures n*ln2hi is exactly representable.
- *		2. In step 1, f may not be representable. A correction term c
- *	 	   for f is computed. It follows that the correction term for
- *		   f - t (the leading term of log(1+f) in step 2) is c-c*x. We
- *		   add this correction term to n*ln2lo to attenuate the error.
- *
- *
- * Special cases:
- *	log1p(x) is NaN with signal if x < -1; log1p(NaN) is NaN with no signal;
- *	log1p(INF) is +INF; log1p(-1) is -INF with signal;
- *	only log1p(0)=0 is exact for finite argument.
- *
- * Accuracy:
- *	log1p(x) returns the exact log(1+x) nearly rounded. In a test run 
- *	with 1,536,000 random arguments on a VAX, the maximum observed
- *	error was .846 ulps (units 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.

- * REVISED BY K.C. NG on 7/10/85.
- * KERNEL pow_P() REPLACED BY P. McILROY 7/22/92.
- * Required system supported functions:
- *      scalb(x,n)      
- *      logb(x)         
- *	copysign(x,y)	
- *	finite(x)	
- *	drem(x,y)
- *
- * Required kernel functions:
- *	exp__D(a,c)			exp(a + c) for |a| << |c|
- *	struct d_double dlog(x)		r.a + r.b, |r.b| < |r.a|
- *
- * Method
- *	1. Compute and return log(x) in three pieces:
- *		log(x) = n*ln2 + hi + lo,
- *	   where n is an integer.
- *	2. Perform y*log(x) by simulating muti-precision arithmetic and 
- *	   return the answer in three pieces:
- *		y*log(x) = m*ln2 + hi + lo,
- *	   where m is an integer.
- *	3. Return x**y = exp(y*log(x))
- *		= 2^m * ( exp(hi+lo) ).
- *
- * Special cases:
- *	(anything) ** 0  is 1 ;
- *	(anything) ** 1  is itself;
- *	(anything) ** NaN is NaN;
- *	NaN ** (anything except 0) is NaN;
- *	+(anything > 1) ** +INF is +INF;
- *	-(anything > 1) ** +INF is NaN;
- *	+-(anything > 1) ** -INF is +0;
- *	+-(anything < 1) ** +INF is +0;
- *	+(anything < 1) ** -INF is +INF;
- *	-(anything < 1) ** -INF is NaN;
- *	+-1 ** +-INF is NaN and signal INVALID;
- *	+0 ** +(anything except 0, NaN)  is +0;
- *	-0 ** +(anything except 0, NaN, odd integer)  is +0;
- *	+0 ** -(anything except 0, NaN)  is +INF and signal DIV-BY-ZERO;
- *	-0 ** -(anything except 0, NaN, odd integer)  is +INF with signal;
- *	-0 ** (odd integer) = -( +0 ** (odd integer) );
- *	+INF ** +(anything except 0,NaN) is +INF;
- *	+INF ** -(anything except 0,NaN) is +0;
- *	-INF ** (odd integer) = -( +INF ** (odd integer) );
- *	-INF ** (even integer) = ( +INF ** (even integer) );
- *	-INF ** -(anything except integer,NaN) is NaN with signal;
- *	-(x=anything) ** (k=integer) is (-1)**k * (x ** k);
- *	-(anything except 0) ** (non-integer) is NaN with signal;
- *
- * Accuracy:
- *	pow(x,y) returns x**y nearly rounded. In particular, on a SUN, a VAX,
- *	and a Zilog Z8000,
- *			pow(integer,integer)
- *	always returns the correct integer provided it is representable.
- *	In a test run with 100,000 random arguments with 0 < x, y < 20.0
- *	on a VAX, the maximum observed error was 1.79 ulps (units 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.
