ctanh, ctanhf, ctanhl - complex hyperbolic tangent functions
double complex ctanh(double complex z);
float complex ctanhf(float complex z);
long double complex ctanhl(long double complex z);
These functions shall compute the complex hyperbolic tangent of z.
These functions shall return the complex hyperbolic tangent value.
No errors are defined.
The following sections are informative.
