NAME
     al_fixcos - Allegro 5 API

SYNOPSIS
	    #include <allegro5/allegro.h>

	    al_fixed al_fixcos(al_fixed x);

DESCRIPTION
     This  function finds the cosine of a value using a lookup table.  The input
     value must be a fixed point binary angle.

     Example:

	    al_fixed angle;
	    float result;

	    /* Set the binary angle to 45 degrees. */
	    angle = al_itofix(32);

	    /* The cosine of 45 degrees is about 0.7071. */
	    result = al_fixtof(al_fixcos(angle));
	    assert(result > 0.7 && result < 0.71);

RETURN VALUE
     Returns the cosine of a fixed point binary format angle as  a  fixed  point
     value.
