hypot calculates the Euclidean distance:
between
the origin (0,0) and a point represented by the Cartesian coordinates (x,y).
hypotf differs
only in the type of its arguments and result.
hypot,
hypotf
[distance from origin]
SYNOPSIS
#include <math.h>
double hypot(double x, double y);
float hypotf(float x, float y);
DESCRIPTION
hypot
calculates the Euclidean distance: between
the origin (0,0) and a point represented by the Cartesian coordinates (x,y).
hypotf differs
only in the type of its arguments and result.
RETURNS
Normally, the distance value
is returned. On overflow, hypot
returns HUGE_VAL
and sets errno
to ERANGE.
You can change the error treatment with matherr.
COMPLIANCE
hypot
and hypotf
are not ANSI C.
