+ *
+ * Method :
+ *	Based on 
+ *		acosh(x) = log [ x + sqrt(x*x-1) ]
+ *	we have
+ *		acosh(x) := log1p(x)+ln2,	if (x > 1.0E20); else		
+ *		acosh(x) := log1p( sqrt(x-1) * (sqrt(x-1) + sqrt(x+1)) ) .
+ *	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
+ *	maximum observed error was 3.30 ulps (units of the last place) at

+ *
+ *    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.

+ * 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

+ *
+ * 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.

+ * 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.

+	 propagating from its left will fall into the hole at its
+	 least significant bit and stop.  Since there will be no
+	 carry from its most significant bit, the LSB of the
+	 byte to the left will be unchanged, and the zero will be
+	 detected.
+
+	 2) Is this worthwhile?  Will it ignore everything except
+	 zero bytes?  Suppose every byte of LONGWORD has a bit set
+	 somewhere.  There will be a carry into bit 8.  If bit 8
+	 is set, this will carry into bit 16.  If bit 8 is clear,
+	 one of bits 9-15 must be set, so there will be a carry
+	 into bit 16.  Similarly, there will be a carry into bit
+	 24.  If one of bits 24-30 is set, there will be a carry
+	 into bit 31, so all of the hole bits will be changed.
+
+	 The one misfire occurs when bits 24-30 are clear and bit
+	 31 is set; in this case, the hole at bit 31 is not
+	 changed.  If we had access to the processor carry flag,
+	 we could close this loophole by putting the fourth hole
+	 at bit 32!
+
+	 So it ignores everything except 128's, when they're aligned
+	 properly.
+
+	 3) But wait!  Aren't we looking for C, not zero?

+ * REVISED BY K.C. NG on 7/10/85.
+ * KERNEL pow_P() REPLACED BY P. McILROY 7/22/92.

+ *      logb(x)         
+ *	copysign(x,y)

+ *	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.

+	 carry from its most significant bit, the LSB of the
+	 byte to the left will be unchanged, and the zero will be
+	 detected.
+
+	 2) Is this worthwhile?  Will it ignore everything except
+	 zero bytes?  Suppose every byte of LONGWORD has a bit set
+	 somewhere.  There will be a carry into bit 8.  If bit 8
+	 is set, this will carry into bit 16.  If bit 8 is clear,
+	 one of bits 9-15 must be set, so there will be a carry
+	 into bit 16.  Similarly, there will be a carry into bit
+	 24.  If one of bits 24-30 is set, there will be a carry
+	 into bit 31, so all of the hole bits will be changed.
+
+	 The one misfire occurs when bits 24-30 are clear and bit
+	 31 is set; in this case, the hole at bit 31 is not
+	 changed.  If we had access to the processor carry flag,
+	 we could close this loophole by putting the fourth hole
+	 at bit 32!
+
+	 So it ignores everything except 128's, when they're aligned
+	 properly.
+
+	 3) But wait!  Aren't we looking for C as well as zero?
+	 Good point.  So what we do is XOR LONGWORD with a longword,
+	 each of whose bytes is C.  This turns each byte that is C
+	 into a zero.  */

+ * Method :

+ *	2. Hypot(x,y) is computed by:

+ *		
+ *				       y
+ *		hypot = x + -----------------------------
+ *			 		    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

+ * functions temporarily. They are not universal, and some of them are very
+ * slow (in particular, drem and sqrt is extremely inefficient). Each 
+ * computer system should have its implementation of these functions using

+ ******************************************************************************
+ *
+ * IEEE 754 required operations:
+ *     drem(x,p) 
+ *              returns  x REM y  =  x - [x/y]*y , where [x/y] is the integer
+ *              nearest x/y; in half way case, choose the even one.
+ *     sqrt(x) 
+ *              returns the square root of x correctly rounded according to 
+ *		the rounding mod.
+ *
+ * IEEE 754 recommended functions:
+ * (a) copysign(x,y) 
+ *              returns x with the sign of y. 
+ * (b) scalb(x,N) 
+ *              returns  x * (2**N), for integer values N.
+ * (c) logb(x) 
+ *              returns the unbiased exponent of x, a signed integer in 
+ *              double precision, except that logb(0) is -INF, logb(INF) 
+ *              is +INF, and logb(NAN) is that NAN.
+ * (d) finite(x) 
+ *              returns the value TRUE if -INF < x < +INF and returns 
+ *              FALSE otherwise.

+; Common overhead is about 11 cycles/invocation.
+
+; The speed for S2_LIMB >= 0x10000 is approximately 21 cycles/limb.  (The
+; pipeline stalls 2 cycles due to WB contention.)
+
+; The speed for S2_LIMB < 0x10000 is approximately 16 cycles/limb.  (The
+; pipeline stalls 2 cycles due to WB contention and 1 cycle due to latency.)
+
+; To enhance speed:
+; 1. Unroll main loop 4-8 times.
+; 2. Schedule code to avoid WB contention.  It might be tempting to move the
+;    ld instruction in the loops down to save 2 cycles (less WB contention),
+;    but that looses because the ultimate value will be read from outside
+;    the allocated space.  But if we handle the ultimate multiplication in
+;    the tail, we can do this.
+; 3. Make the multiplication with less instructions.  I think the code for
+;    (S2_LIMB >= 0x10000) is not minimal.
+; With these techniques the (S2_LIMB >= 0x10000) case would run in 17 or
