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.
