NAME
       catanh, catanhf, catanhl - complex arc hyperbolic tangent functions

SYNOPSIS
       #include <complex.h>

       double complex catanh(double complex z);
       float complex catanhf(float complex z);
       long double complex catanhl(long double complex z);

DESCRIPTION
       These  functions  shall	compute the complex arc hyperbolic tangent of z, with branch cuts
       outside the interval [-1, +1] along the real axis.

RETURN VALUE
       These functions shall return the complex arc hyperbolic tangent value, in the range  of	a
       strip  mathematically  unbounded  along the real axis and in the interval [-ipi/2, +ipi/2]
       along the imaginary axis.
