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.
