ctanh(3)                   Library Functions Manual                   ctanh(3)

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)
