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.
