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
