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.
