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)
