double complex casin(double complex z);

float complex casinf(float complex z);

long double complex casinl(long double complex z);

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

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

No errors are defined.
