| Description | simple versions: Yi = 1 / Xi2
expanded versions: Yi = 1 / (A*Xi+B)2
The "unprotected" versions (prefix VFu_, VFux_, etc.) do not perform any error handling, which makes them much faster, but riskier than the standard versions. |
|
| Error handling | SING and OVERFLOW errors lead to a default result of HUGE_VAL. |
|
| Return value | FALSE (0), if no error occurred, otherwise TRUE (non-zero) |
