ctanh, ctanhf, ctanhl - complex hyperbolic tangent

  #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.

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 first appeared in glibc in version 2.1.
