    Default 0,9999999=1

    just testing the new postcount feature, spam spam spam <3

    Anyways, a friend of me said that 0,99999999 etc (9's in the infinity) = 1, because you can't do 1 - 0,0(infinite zeros here)1. Imo it isn't that way, because there is always a difference, what are your opinions?
    I made a new script, check it out!.

    0,9999999(infinite) = 0,9999999(infinite)
    1 - 0,0000(infinite zeros ) = 1

    To get from 1 to .9999..., you can't just subtract .000...1, you'd go too far.
    So in essence, they'd have to be the same thing.

    Probably, but it would be harder to make that proof.

    Yes, .59999... = 6. Because, you can't go from 6 to 5.999999..

    there are 101 proofs that it is, in fact, equal to 1. If you don't believe it, then give me a mathematical counter example which shows that it is not equal to one.

    My favorite is assume that
    x = .9999999..... Now times both sides by 10 to get
    10x = 9.999999999.....
    and subtract 1 x from both sides to get
    9x = 9
    divide by 9...
    x = 1

    Please, if you can see where I made a mistake I would love for you to point it out, however if you just want to say that it is different because you lack the understanding of what infinite really means, then don't bother posting.

    wow, no offense but we sound like total geeks when we say stuff like this but i guess half the people here that are 30 or under will probably become very rich, a sweet job, or they won't leave the forum and live with there mom the rest of there lives. Buy the way i agree with Thevoiceinyorhead guy.

    I can't remember what the full theory was (this is another thing), but it was something like that let's say value A, will never be 1 because it has to go through infinite 'subpoints'

    0.999..n will NEVER be equal to one.
    The last decimal will allways make the difference.

    And, I LOL'ed at that formula. Santy is right, the used the formula wrongly.

    But there is no last number.

    And no, they used the formula correctly.

    At least you people understand the formula. I suck at maths so I just let my eyes glaze over when ever I see formulas
