14 /* hypot(x,y)
17 * If (assume round-to-nearest) z=x*x+y*y
21 * So, compute sqrt(x*x+y*y) with some care as
24 * Assume x>y>0;
26 * 1. if x > 2y use
27 * x1*x1+(y*y+(x2*(x+x1))) for x*x+y*y
29 * 2. if x <= 2y use
30 * t1*y1+((x-y)*(x-y)+(t1*y2+t2*y))
32 * y1= y with lower 32 bits chopped, y2 = y-y1.
38 * hypot(x,y) is INF if x or y is +INF or -INF; else
39 * hypot(x,y) is NAN if x or y is NAN.
42 * hypot(x,y) returns sqrt(x^2+y^2) with error less
