NAME
       fixatan	-  Fixed point inverse tangent lookup table. Allegro game pro-
       gramming	library.

SYNOPSIS
       #include	<allegro.h>

       fixed fixatan(fixed x);

DESCRIPTION
       This function finds the inverse tangent of a value using	a  lookup  ta-
       ble.  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.
