NAME

       ccosh, ccoshf, ccoshl - complex hyperbolic cosine

LIBRARY

       Math library (libm, -lm)

SYNOPSIS

       #include <complex.h>

       double complex ccosh(double complex z);
       float complex ccoshf(float complex z);
       long double complex ccoshl(long double complex z);

DESCRIPTION

       These functions calculate the complex hyperbolic cosine of z.

       The complex hyperbolic cosine function is defined as:

           ccosh(z) = (exp(z)+exp(-z))/2
