NAME

       casinh, casinhf, casinhl - complex arc hyperbolic sine functions

SYNOPSIS

       #include <complex.h>

       double complex casinh(double complex z);
       float complex casinhf(float complex z);
       long double complex casinhl(long double complex z);

DESCRIPTION

       These functions shall compute the complex arc hyperbolic sine of z, with branch cuts outside the interval
       [-i, +i] along the imaginary axis.

RETURN VALUE

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