       al_fixatan - Allegro 5 API

SYNOPSIS

              #include <allegro5/allegro.h>

              al_fixed al_fixatan(al_fixed x)

DESCRIPTION

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