Calculates the arc sine of a complex number.

[Format]

#include <complex.h>

float complex casinf(float complex z);

double complex casin(double complex z);

long double complex casinl(long double complex z);

[Parameters]

z Complex number for which arc sine is to be computed

[Return values]

Complex arc sine of z

[Remarks]

The casin function returns the arc sine in the range [–π/2, π/2] on the real axis and in the infinite range on the imaginary axis.
