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 arc hyperbolic sine of z.  If y = casinh(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))

VERSIONS

       These functions first appeared in glibc in version 2.1.

CONFORMING TO

       C99.
