CTANH(3)

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.
