| Description | simple versions: Yi = arcsin ( Xi )
expanded versions: Yi = C * arcsin (A*Xi + B ) |
|
| Error handling | Real versions: DOMAIN errors occur for arguments outside the range −1 ≤ Xi ≤ +1; the default result is NAN ("not-a-number").
The complex versions should be error-proof as long as the parameter C in the expanded versions is not already near the OVERFLOW limit; this very rare error is either detected nor handled. |
|
| Return value | FALSE (0), if no error occurred, otherwise TRUE (non-zero). |
