Description

These functions compute the complex arc sine of z, with branch cuts outside the interval [ -1, +1 ] along the real axis.

Return Values

These functions return the complex arc sine value, in the range of a strip mathematically unbounded along the imaginary axis and in the interval [ -π/2, +π/2 ] along the real axis.

Errors

No errors are defined.
