ctanh(3)                 Library Functions Manual                ctanh(3)

NAME         top

       ctanh, ctanhf, ctanhl - complex hyperbolic tangent

LIBRARY         top

       Math library (libm, -lm)

SYNOPSIS         top

       #include <complex.h>

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

DESCRIPTION         top

       These functions calculate the complex hyperbolic tangent of z.

       The complex hyperbolic tangent function is defined mathematically
       as:

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