ctanh(3)		    Library Functions Manual			ctanh(3)

NAME
     ctanh, ctanhf, ctanhl - complex hyperbolic tangent

LIBRARY
     Math library (libm, -lm)

SYNOPSIS
     #include <complex.h>

     double complex ctanh(double complex z);
     float complex ctanhf(float complex z);
     long double complex ctanhl(long double complex z);

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)
