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)
