hypot − Euclidean distance function
#include <math.h>
double hypot(double x, double y);
float hypotf(float x, float y);
long double hypotl (long double x, long double y);
The hypot() function returns the 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.
SVID 3, BSD 4.3, C99. The float and the long double variants are C99 requirements.
