lz_arccosecant
The angle whose cosecant is the number.
long lz_arccosecant( CLZNumber* leftOperand, CLZNumber* targetNumber = nullptr );arcsin(1/x), in [−π/2, π/2], correctly rounded in the thread's unit; arccsc 2 is exactly 30°. Between −1 and 1 there is no real angle: kFailed, flagged not-a-number.
Examples
| Call | Answer |
|---|---|
lz_arccosecant( 2 ) | 0.523598775598298873077107230546583814 |
lz_arccosecant( 2 ) degrees | 30 |
Each answer is what Addaptic printed for the call, in radians, at 36 places unless a setting is shown.
Returns
kNoError (0) when the answer is written. Otherwise an error code, with the answer flagged infinite or not-a-number; see Errors and flags.
