hypot(3) BSD Library Functions Manual hypot(3)
NAME
hypot -- euclidean distance function
SYNOPSIS
#include <math.h>
double
hypot(double x, double y);
long double
hypotl(long double x, long double y);
float
hypotf(float x, float y);
DESCRIPTION
The hypot() function computes the sqrt(x*x+y*y) without undue overflow or
underflow.
SPECIAL VALUES
hypot(x, y) , hypot(y, x) , and hypot(x, -y) are equivalent.
hypot(x, +-0) is equivalent to fabs(x).
hypot(+-infinity, y) returns +infinity even if y is a NaN.
SEE ALSO
cabs(3), math(3), sqrt(3)
STANDARDS
The hypot() function conforms to ISO/IEC 9899:2011.
