NAME

ctanh, ctanhf, ctanhl - complex hyperbolic tangent

LIBRARY

Math library (libm, -lm)

SYNOPSIS

bash

#include <complex.h>

bash

double complex ctanh(double complex \nz\n);\n
\nfloat complex ctanhf(float complex \nz\n);\n
\nlong double complex ctanhl(long double complex \nz\n);

DESCRIPTION

These functions calculate the complex hyperbolic tangent of z.

The complex hyperbolic tangent function is defined mathematically as:

bash

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