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.
