CTANH(3)                Linux Programmer's Manual               CTANH(3)

NAME         top

       ctanh, ctanhf, ctanhl - complex hyperbolic tangent

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);

       Link with -lm.

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)

VERSIONS         top

       These functions first appeared in glibc in version 2.1.
