CASIN(3)                   Library Functions Manual                   CASIN(3)

     casin, casinf, casinl - complex arc sine functions

     #include <complex.h>

     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.
