# `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 `sqrt(X*X + Y*Y)' 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'.

*Portability*
`hypot' and `hypotf' are not ANSI C.
