NAME
       hypot, hypotf, hypotl - Euclidean distance function

SYNOPSIS
       #include <math.h>

       double hypot(double x, double y);

       float hypotf(float x, float y);

       long double hypotl (long double x, long double y);

DESCRIPTION
       The hypot() function returns sqrt(x*x+y*y).  This is the length of the
       hypotenuse of a right-angle triangle with sides of length x and y,  or
       the distance of the point (x,y) from the origin.

CONFORMING TO
       SVID  3, BSD 4.3, C99.  The float and the long double variants are C99
       requirements.
