ctanh(3) Library Functions Manual ctanh(3)

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)

These functions were added in glibc 2.1.

For an explanation of the terms used in this section, see attributes(7).
