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.
