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.
