- * 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
- *			    			  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.
