HYPOT(3) BSD Library Functions Manual HYPOT(3) NAME hypot -- euclidean distance function SYNOPSIS #include <math.h> double hypot(double x, double y); long double hypotl(long double x, long double y); float hypotf(float x, float y); DESCRIPTION The hypot() function computes the sqrt(x*x+y*y) without undue overflow or underflow. SPECIAL VALUES hypot(x, y) , hypot(y, x) , and hypot(x, -y) are equivalent. hypot(x, +-0) is equivalent to fabs(x). hypot(+-infinity, y) returns +infinity even if y is a NaN. SEE ALSO cabs(3), math(3), sqrt(3) STANDARDS The hypot() function conforms to ISO/IEC 9899:1999(E). 4th Berkeley Distribution January 28, 2003 4th Berkeley Distribution |
