ccosh(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.
