NAME
       ctanh, ctanhf, ctanhl - complex hyperbolic tangent
SYNOPSIS
       #include <complex.h>
       double complex ctanh(double complex z);
       float complex ctanhf(float complex z);
       long double complex ctanhl(long double complex z);
       Link with -lm.
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)
VERSIONS
       These functions first appeared in glibc in version 2.1.
