PROLOG

       This  manual  page  is part of the POSIX Programmer's Manual.  The Linux implementation of
       this interface may differ (consult the corresponding Linux  manual  page  for  details  of
       Linux behavior), or the interface may not be implemented on Linux.

NAME

       ccosh, ccoshf, ccoshl — complex hyperbolic cosine functions

SYNOPSIS

       #include <complex.h>

       double complex ccosh(double complex z);
       float complex ccoshf(float complex z);
       long double complex ccoshl(long double complex z);

DESCRIPTION

       The functionality described on this reference page is aligned with the ISO C standard. Any
       conflict between the requirements described here and the ISO C standard is  unintentional.
       This volume of POSIX.1‐2008 defers to the ISO C standard.

       These functions shall compute the complex hyperbolic cosine of z.

RETURN VALUE

       These functions shall return the complex hyperbolic cosine value.
