NAME
       casinh, casinhf, casinhl - complex arc sine hyperbolic

SYNOPSIS
       #include <complex.h>

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

       Link with -lm.

DESCRIPTION
       The  casinh()  function	calculates  the	 complex asinh().  If y = cas‐
       inh(z), then z = csinh(y).  The imaginary part of y is  chosen  in  the
       interval [-pi/2,pi/2].

       One has casinh(z) = clog(z+csqrt(z*z+1)).
