Computes the complex hyperbolic tangent.
#include <complex.h> double complex ctanh (z) double complex z; float complex ctanhf (z) float complex z; long double complex ctanhl (z) long double complex z;
The ctanh, ctanhf, and ctanhl subroutines compute the complex hyperbolic tangent of z.
| z | Specifies the value to be computed. |
The ctanh, ctanhf, and ctanhl subroutines return the complex hyperbolic tangent value.
