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

SYNOPSIS
     c99 [ flag... ] file... -lm [ library... ]
     #include 

     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 [ -ipi/2,  +ipi/2  ]
     along the imaginary axis.

ERRORS
     No errors are defined.
