NAME

       fixatan - Fixed point inverse tangent lookup table. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       fixed fixatan(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:

          fixed result;

          /* Sets `result' to binary angle 13. */
          result = fixatan(ftofix(0.326));

RETURN VALUE

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