ccosh(3) Library Functions Manual ccosh(3)

NAME top

   ccosh, ccoshf, ccoshl - complex hyperbolic cosine

LIBRARY top

   Math library (_libm_, _-lm_)

SYNOPSIS top

   **#include <complex.h>**

   **double complex ccosh(double complex** _z_**);**
   **float complex ccoshf(float complex** _z_**);**
   **long double complex ccoshl(long double complex** _z_**);**

DESCRIPTION top

   These functions calculate the complex hyperbolic cosine of _z_.

   The complex hyperbolic cosine function is defined as:

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

STANDARDS top

   C11, POSIX.1-2008.

HISTORY top

   glibc 2.1.  C99, POSIX.1-2001.
