NAME

     ctanh, ctanhf, ctanhl - complex hyperbolic tangent

SYNOPSIS

     #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.

DESCRIPTION

     These functions calculate the complex hyperbolic tangent of z.

     The complex hyperbolic tangent function is defined mathematically as:

         ctanh(z) = csinh(z) / ccosh(z)

VERSIONS

     These functions first appeared in glibc in version 2.1.
