ccosh - Man Page

Math library (libm, -lm)

#include <complex.h>

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

These functions calculate the complex hyperbolic cosine of z.

The complex hyperbolic cosine function is defined as:

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

These functions first appeared in glibc in version 2.1.
