This is not a real posting. Instead, it is just a placeholder posted on 09/09/09 at 09:09:09. Sorry for that! The comment thread can be used for any discussions. ;-)

By the way, the numbers could lead you to ask whether 0.9999... is equal to 1.0000...

Well, you may define your numbers in any way you want. But if want these particular, possibly infinite sequences of decimal digits to represent a number system (namely the set of real numbers) that satisfies (x/3)*3=1, then you're forced to accept that 0.9999... must be identified with 1.0000.... simply because 1/3=0.3333... and 0.3333...*3 = 0.9999... ;-)
