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.
