ctanh, ctanhf, ctanhl − complex hyperbolic tangent
Math library (libm, −lm)
#include <complex.h>
double
complex ctanh(double complex z);
float complex ctanhf(float complex z);
long double complex ctanhl(long double complex
z);
These functions calculate the complex hyperbolic tangent of z.
The complex hyperbolic tangent function is defined mathematically as:
ctanh(z) = csinh(z) / ccosh(z)
