cpp/numeric/complex/asin

Computes complex arc sine of a complex value. Branch cut exists outside the interval $[−1, +1]$ along the real axis.

Return value
If no errors occur, complex arc sine of is returned, in the range of a strip unbounded along the imaginary axis and in the interval $[−π/2, +π/2]$ along the real axis.

Errors and special cases are handled as if the operation is implemented by, where is the imaginary unit.
