SYNOPSIS#include <complex.h>double complex ccosh(double complex z); float complex ccoshf(float complex z); long double complex ccoshl(long double complex z);

---

DESCRIPTIONThese functions calculate the complex hyperbolic cosine of z. The complex hyperbolic cosine function is defined as: ccosh(z) = (exp(z)+exp(−z))/2

---

VERSIONSThese functions were added in glibc 2.1.

---

STANDARDSC99, POSIX.1-2001, POSIX.1-2008.
