Hell, I learned this In my trigonometry class.

And a number that goes on infinately is not irattional, just impractical to use.

There is no real practical use to knowing 1 = 0.999..., but that doesn't change the fact that it does.

And PG made 2 of those threads? WTF?


Edit: Neotifa, you can't add a 9 to the end of something that has no end. So in this case, there are not always 9's to add to the end, proving your argument false.
