hypot(3M)                                                         hypot(3M)

NAME
     hypot - Euclidean distance function

SYNOPSIS
     cc [flag ...] file ... -lm [library ...]

     #include <math.h>

     double hypot(double x, double y);

DESCRIPTION
     hypot() computes the length of the hypotenuse of a right-angled triangle
     (see the Programmer's Reference Manual): sqrt(x * x + y * y)

RESULT
     When the correct value would overflow, hypot() returns HUGEVAL and
     sets errno to ERANGE.

     If x or y is NaN, errno is set to EDOM.
