Okay if this was rounding them then just .9 or even .999999999999999999999999999 would be = to 1,but if it was no rounding, then .9 would be closest to one then the more 9's you get the farther you get from a one

Wrong, you get closer with more numbers following in the decimal.

.99 is not closer to 1 then .9

This is all leading back to what I said already, if at the beginning when they first thought up the concept of a number system they thought about it a lot more than what they obviously didn't, then we wouldn't have friggin problems like these. ANARKY xD

I'm confused.  Are you saying that .9 is closer to 1 than .99 or what?
.99 is closer to 1 because it is .09 more than .9 (or .90) and so on and so forth.  It's like saying that 99 is closer to 100 than 90.

I could count that as spam, but I could just as easily argue that 0.00~1 is infinity as well: 0.00000000000000000000000 ...

And since the zeros continue on infinitely, the 1 at the end never comes into existance, because there is no end. Therefore, the difference between 0.999~ and 1 is 0. See? Call it false logic if you wish, but in doing so you will be dubbing your logic false as well.

1 divided by 3 -> 0.333333333333..... multiplied by 3 = 0.99999999999999.....

So, 0.9999999......... = 1.

I like this algebraic proof my university math professor showed us:

a = 0,999...

Multiply by 10:  10a = 9,999...
Substract a: 10a - a = 9
Divide by 9: a = 1

That's where he gets all his jokes from... >.>

P.S. 0.999~ ≠ 1 because of the 'piece of string' argument QED.

And

No that's just exploiting the algebraic system to prove something that isn't actually true, there are many other things you can 'prove' using it too, but they aren't accurate. THE NUMBER SYSTEM IS FUCKED get a new one earth.

HOLY CRAP, .999... IS EXACTLY THE SAME AS ONE.
excuse my caps lock but this is a basic elementary fact.  I don't see how this can be a debate. It's MATH.  Either you're right or wrong.  And .999... is EXACTLY  1.

Do you guys think Gauss is wrong?  Is Leibnitz lying?  They're only like among the top 10 smartest people who ever lived.

Proof 1: fractions.
Code: [Select]
0.333…   = 1⁄3
3 × 0.333…   = 3 × 1⁄3
0.999…   = 1

Proof 2: algebra.
Code: [Select]
c = 0.999…
10c = 9.999…
10c − c = 9.999… − 0.999…
9c = 9
c = 1

There's like a million other proofs with more complicated things, but this should be enough.

There's no such thing as .000~1.  That's called zero.  And no, you can't prove 1=2.  They divided by zero.  MATH IS MATH, AND IT IS THE LAW.  MATH DOESN'T NEED ANYONES OPINION.

YOU CAN'T PROVE SOMETHING THAT ISN'T TRUE, PANZER.  MATH IS NOT INACCURATE.  THE NUMBER SYSTEM IS PERFECT BY DEFINITION.

RAWR.

and hi.

ok the way i see it is that .9 = .900000000000000000 and that is only .1 away from well 1 but .999999999999999999 is only .00000000000000001 away from 1

but since its ,999999999999999999 infinity  it would be .000000 infinity zeros and then 1 as the last number since infinity zeros go on forever  that dose not work

.99999999-->  will continually get closer to 1, but never reach it.   draw a graph of y=1/x to see a visual example.
Plonkoon wins for giving a tangible explination. Applaud.

And swarmer:

0.333…   = 1⁄3

is still rounding. Just go with fractions people.

Smite!

0.9999~ is impossible to graph, at least, completely. It's like trying to see where the y = x line ends by making a graph out of it.

And by 0.33333 he meant 0.3333~

Quote
Students of mathematics often reject the equality of 0.999… and 1, for reasons ranging from their disparate appearance to deep misgivings over the limit concept and disagreements over the nature of infinitesimals. There are many common contributing factors to the confusion:
    * Students are often "mentally committed to the notion that a number can be represented in one and only one way by a decimal." Seeing two manifestly different decimals representing the same number appears to be a paradox, which is amplified by the appearance of the seemingly well-understood number 1.[12]
    * Some students interpret "0.999…" (or similar notation) as a large but finite string of 9s, possibly with a variable, unspecified length. If they accept an infinite string of nines, they may still expect a last 9 "at infinity."[13]
    * Intuition and ambiguous teaching lead students to think of the limit of a sequence as a kind of infinite process rather than a fixed value, since a sequence need not reach its limit. Where students accept the difference between a sequence of numbers and its limit, they might read "0.999…" as meaning the sequence rather than its limit.[14]
    * Some students regard 0.999... as having a fixed value which is less than 1 but by an infinitely small amount.
    * Some students believe that the value of a convergent series is an approximation, not the actual value.

Incorrect.  The graph of x = .999~ is the same as the graph of x = 1, since, well, .999~ = 1.

NO.  .333... is EXACTLY EQUAL to 1/3.  It's not rounding.

If you have infinity zeros you can't add a 1 as the last number.  There is no last number.  That's the definition of infinity.  1 - .999... = 0.

.99999999-->  will continually get closer to 1, but never reach it.   draw a graph of y=1/x to see a visual example.

No, you draw a graph yourself and see the fact that it does reach 1.  You proved your own point wrong.  Rawr.

PEOPLE, MATH IS NOT DEBATABLE.  LOOK UP THE SCIENTIFIC ANSWER.  .999... IS 100% EXACTLY EQUAL TO 1.  It's mathematically proven, and every single credible scientist supports it.  This is not a debate.  It's a question.  And the answer is yes, it is equal to 1.

I think it's okay to not know this fact, because intuitively, it doesn't seem equal.  That's okay, we all need to learn.  But when you believe with such fervor that it's not equal, when all it takes is a quick search to verify your claims, then you've got a problem.

Wrong, you get closer with more numbers following in the decimal.

.99 is closer to 1 because it is .09 more than .9 (or .90) and so on and so forth.  It's like saying that 99 is closer to 100 than 90.

Bah, misunderstandings/mistypings. I thought Wolfman was saying that the more 9s after the decimal, the farther you were from one. Then, I accidentally switched the two numbers when I said "
.99 is not closer to 1 then .9" I meant to say  ".9 is not closer to 1 then .99"
