NAME

ccosh, ccoshf, ccoshl − complex hyperbolic cosine

SYNOPSIS

#include <complex.h>

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

Link with −lm.

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

VERSIONS

These functions first appeared in glibc in version 2.1.
