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

SYNOPSIS
       cc [ flag... ] file... -lm [ library... ]
       #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 compute the complex arc hyperbolic tangent of z, with branch cuts outside the interval [ -1, +1 ] along the real axis.

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

ERRORS
       No errors are defined.
