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.
