+/* 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

+ *			 		    			  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.
