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.
