| Description | simple versions: Yi = 1.0 / Xi
expanded versions: Yi = 1.0 / (A*Xi+B) |
|
| Error handling | Normal versions (VF_, VFx_ etc.): SING and OVERFLOW errors lead to a result of ±HUGE_VAL.
Unprotected versions (VFu_, VFux_ etc.): no error handling. |
|
| Return value | FALSE (0), if no error occurred, otherwise TRUE (non-zero) |
