NAME

       ctanh, ctanhf, ctanhl - complex hyperbolic tangent

LIBRARY

       Math library (libm, -lm)

SYNOPSIS

       #include <complex.h>

       double complex ctanh(double complex z);
       float complex ctanhf(float complex z);
       long double complex ctanhl(long double complex z);

DESCRIPTION

       These functions calculate the complex hyperbolic tangent of z.

       The complex hyperbolic tangent function is defined mathematically as:

           ctanh(z) = csinh(z) / ccosh(z)
