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.   The	return
       value will be in	radians.
