              al_fixed al_fixatan(al_fixed x)

DESCRIPTION

       This  function finds the inverse tangent of a value using a lookup table.  The input value
       must be a fixed point radian.  The inverse tangent is the value whose tangent is x.

       Example:

              al_fixed result;

              /* Sets result to binary angle 13. */
              result = al_fixatan(al_ftofix(0.326));

RETURN VALUE

       Returns the inverse tangent of a fixed point value,  measured  as  a  fixed  point  binary
       format angle.
