- *	
- *	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.

- * 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

- *
- * DESCRIPTION
- *
- *    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.

-/* HYPOT(X,Y)
- * RETURN THE SQUARE ROOT OF X^2 + Y^2  WHERE Z=X+iY
- * DOUBLE PRECISION (VAX D format 56 bits, IEEE DOUBLE 53 BITS)
- * CODED IN C BY K.C. NG, 11/28/84; 
- * REVISED BY K.C. NG, 7/12/85.
- *
- * Required system supported functions :
- *	copysign(x,y)
- *	finite(x)
- *	scalb(x,N)
- *	sqrt(x)
- *
- * Method :
- *	1. replace x by |x| and y by |y|, and swap x and
- *	   y if y > x (hence x is never smaller than y).
- *	2. Hypot(x,y) is computed by:
- *	   Case I, x/y > 2
- *		
- *				       y
- *		hypot = x + -----------------------------
- *			 		    2
- *			    sqrt ( 1 + [x/y]  )  +  x/y
- *
- *	   Case II, x/y <= 2 
- *				                   y
- *		hypot = x + --------------------------------------------------
- *				          		     2 
- *				     			[x/y]   -  2
- *			   (sqrt(2)+1) + (x-y)/y + -----------------------------
- *			 		    			  2
- *			    			  sqrt ( 1 + [x/y]  )  + sqrt(2)
- *
- *
- *
- * Special cases:
- *	hypot(x,y) is INF if x or y is +INF or -INF; else
- *	hypot(x,y) is NAN if x or y is NAN.
- *
- * Accuracy:
- * 	hypot(x,y) returns the sqrt(x^2+y^2) with error less than 1 ulps (units
- *	in the last place). See Kahan's "Interval Arithmetic Options in the
- *	Proposed IEEE Floating Point Arithmetic Standard", Interval Mathematics
- *      1980, Edited by Karl L.E. Nickel, pp 99-128. (A faster but less accurate
- *	code follows in	comments.) In a test run with 500,000 random arguments
- *	on a VAX, the maximum observed error was .959 ulps.
- *
- * 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.
