ctanhf (3) Linux Manual Page
ctanh, ctanhf, ctanhl – complex hyperbolic tangent
Synopsis
#include <complex.h> double complex ctanh(double complex z);
float complex ctanhf(float complex z);
long double complex ctanhl(long double complex z);
Link with -lm.
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 first appeared in glibc in version 2.1.Attributes
