ccosh, ccoshf, ccoshl - complex hyperbolic cosine
Math library (libm, -lm)
#include <complex.h>
double complex ccosh(double complex z); float complex ccoshf(float complex z); long double complex ccoshl(long double complex z);
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 were added in glibc 2.1.
