NAME
       casin, casinf, casinl - complex arc sine functions

SYNOPSIS
       #include <complex.h>

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

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

RETURN VALUE
       These  functions  shall 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.

ERRORS
