Interesting question. Does 1.99999999999... = 2

[Aflux]

What you are saying is that different things are the same as 1.9rec. is different to 2.

So a cat is different to a dog, therefore they are not the same?

[Concentric2]

Just as the 0.999.. number is infinately big, the difference between it and 1 is infinately small, but being infinately small doesn't make it nothing, so there is still a difference.

[BL!NKEY]

1/3 = .333...

2/3 = .666...

3/3 = .999...

I might not be the best at explaining it but wikipedia does a good job.

by infinitely small you are meaning .000...1 which is not a real limit number.

You cannot have reoccurring numbers to infinity and then another number at the end.

There is no difference

I didn't say anything about it being recurring.

In any case, if a number is infinitely small you can't say what goes on the end of it because you're giving it an ending.

no its not 2

[Shawnstra]

It never becomes 2, it just gets closer to 2 with every "9" added.

[[DC]eption]

No it 2 is 2 and 1.9999 is 1.9999.

[BL!NKEY]

It never becomes 2, it just gets closer to 2 with every "9" added.

But it never ends. There is no last digit.

there is no number that is in-between 2 and 1.999...

No it 2 is 2 and 1.9999 is 1.9999.

we are not talking about 1.9999

this is 2 and 1.999... repeating forever

1.9999999999 = 2 (1dp) :p
there is a theory, in my tiredness and bad maths thats proberly wrong though
