#include <complex.h>

double complex casin(double complex z);
float complex casinf(float complex z);

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 [ −??/2, +??/2 ] along the real axis.

Errors

No errors are defined.
