| Description | simple versions: Yi = cosec2 ( Xi )
expanded versions: Yi = C * cosec2 ( A*Xi + B )
Calculating the squared trigonometric functions directly is faster and sometimes more accurate than first calculating the trigonometric function itself and squaring it afterwards. |
|
| Error handling | For SING, OVERFLOW, and TLOSS errors, the default result is ±HUGE_VAL. |
|
| Return value | FALSE (0), if no error occurred, otherwise TRUE (non-zero). |
