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.
