I think id also depends on what tenth are you using, I mean if you say that after 0.999 goes 1 then its 0.999 or 0.9999 or 0.99999 but if you choose to go from 0.999 to 0.9999 then of course there are numbers but you can go to infinity but you will still end up at 0.9 you can go to quadrillions and still you will end up at 9, only if they would invent another numberbut it still would end at that one, so I guess this has something in it.. that my thoughts
