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.
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.
