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 9899:2011.
