HYPOT(3)           Linux Programmer's Manual           HYPOT(3)





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.

CONFORMING TO
       SVID 3, BSD 4.3, C99.  The float  and  the  long  double
       variants are C99 requirements.
