The article found on Wikipedia.org, on the topic "0.999..." seems to accept that 0.999...=1. I don't. The civilized world bases its numerical system on groups of ten:

1 2 3 4 5 6 7 8 9 10

Using this method, 0.9 = 9/10, of course. But what if a civilization decided to base its numerical system on groups of what we call "twelve"? It might look something like this:

1 2 3 4 5 6 7 8 9 A B 10

"10", to this hypothetical civilization, would be the equivalent to our "twelve".

.6 would be equal to 1/2.

What if a civilization based their numerical system on groups of what we call "five"? It might look something like this:

1 2 3 4 10

Their .4 would be the equivalent to our .8, or 8/10.

In conclusion, 0.999...=1 just because we decided to assign "9", the ninth number, as our highest valued digit? In the numeric system of the first of the two suggested hypothetical civilizations, their .B is equivalent to our 11/12. Their .B is closer to 1 than our .9, or 9/10.

If you think that 0.999...=1, then you must also agree that 0.888...=1, because when using the second suggested hypothetical civilization's numeric system, that's the best you've got.

That's why I say, "0.999... does not equal 1, no matter how hard it tries".
