0.999... = 1 ??

Hey,

I was just reading about this and thought it was interesting.

Apparently, from what I have read, 0.999... = 1
(where the 999... represent an infinite series of 9's)

There were a few good arguments for this 'fact' and also a few arguments against it...

What I want to know is, is this actually true, a fact, or merely a 'theory' ?

Is 0.999... = 1 just as valid as 1+1 = 2 ?
