SYNOPSIS#

#include <complex.h>

double complex ccosh(double complex \nz\n);\n
\nfloat complex ccoshf(float complex \nz\n);\n
\nlong double complex ccoshl(long double complex \nz\n);

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
