     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.

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