| Description | Yi = sqrt( Xi2 + C2 )
This is a variant of the famous Pythagorean theorem for the hypotenuse of a right triangle. |
|
| Error handling | OVERFLOW errors lead to a default result of HUGE_VAL. Unlike the treatment of the ANSI C function hypot by several compilers, only an overflowing final result is regarded as an error. Intermediate overflows (by the calculation of the square) are avoided by appropriate scaling. |
|
| Return value | FALSE (0), if no error occurred, otherwise TRUE (non-zero). |
