lzc_cotangent
The cotangent of a complex angle.
long lzc_cotangent( CLZComplex* leftOperand, CLZComplex* targetNumber = nullptr );Each part correctly rounded, the whole angle in the thread's unit. A pole on the real axis, such as nought, is the point at infinity, kDivideByZero.
Examples
| Call | Answer | Returns |
|---|---|---|
lzc_cotangent( 1 + 1i ) | 0.217621561854402681365134243605238074 − 0.868014142895924948635849208916273888i | kNoError |
lzc_cotangent( 0 + 0i ) | the point at infinity | kDivideByZero |
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.
