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.
