| Description | simple version: Yi = sqrt( Xi2 + Yi2 )
expanded version: Yi = sqrt( (A*Xi+B)2 + Yi2 )
These are variants of the Pythagoras formula for the hypotenuse of a right triangle. |
|
| Error handling | OVERFLOW errors lead to a default result of HUGE_VAL. (Intermediate overflows are avoided by appropriate scaling.) |
|
| Return value | FALSE (0), if no error occurred, otherwise TRUE (non-zero). |
