NAME
hypot, hypotf, hypotl - Euclidean distance functionSYNOPSIS
#include <math.h> double hypot(double x, double y);
float hypotf(float x, float y);
long double hypotl(long double x, long double y);
Link with -lm.
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
hypot(), hypotf(), hypotl(): _BSD_SOURCE || _SVID_SOURCE || _XOPEN_SOURCE >= 500 || _ISOC99_SOURCE; or cc -std=c99
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
SVr4, 4.3BSD, C99. The float and long double variants are C99 requirements.SEE ALSO
