_hypot, hypotf
Visual Studio 2008
Calculates the hypotenuse.
double _hypot( double x, double y ); float _hypotf( float x, float y );
_hypot returns the length of the hypotenuse if successful or INF (infinity) on overflow. The errno variable is set to ERANGE on overflow. You can modify error handling with _matherr.
For more information about this and other return codes, see _doserrno, errno, _sys_errlist, and _sys_nerr.
