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)

VERSIONS

These functions were added in glibc 2.1.
