ctanh(3) Library Functions Manual ctanh(3)
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)
