+/* 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.
