| Description | simple versions: Yi = 2 Xi
expanded versions: Yi = C * 2 (A*Xi+B)
Two is raised to the Xi'th power. These function names are used as synonyms for VF_pow2 etc. |
|
| Error handling | OVERFLOW errors lead to a default result of ±HUGE_VAL. |
|
| Return value | FALSE (0), if no error occurred, otherwise TRUE (non-zero) |
