ccosh, ccoshf, ccoshl - complex hyperbolic cosine


   #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.


   These functions calculate the complex hyperbolic cosine of z.

   The complex hyperbolic cosine function is defined as:

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


   These functions first appeared in glibc in version 2.1.


   C99, POSIX.1-2001, POSIX.1-2008.
