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);
Link with -lm.
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.
