PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the  corresponding
       Linux  manual page for details of Linux behavior), or the interface may
       not be implemented on Linux.
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.
