ccoshf (3)

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.
