      The problem is that you learned math in a math class instead of in a poetry class

      I honestly can't tell if Vanguard is trolling or retarded - either way, it's not worth worrying about

      • Does 1.00000 recurring equal 1?
        One day Canada will rule the world, and then we'll all be sorry.

        • Nope, because 1.0-repeating minus 1 doesn't equal 0, it equals 0.0-repeating

            Makes sense. 0.0-repeating has a hidden infinity (don't ask me where it is, if I knew where it was it wouldn't be hidden) so dividing 1 by 1.0 is like dividing 1 by infinity.

              In computers, .999 repeating is not the same as 1.
              Any system that represents .999 repeating should confirm that it is equal to 1.

              • Also, to answer your question, Mathematica.

                Code:
                Sum[9/10^k, {k, 1, Infinity}]==1
                True

                • People have already shown Wolfram Alpha (i.e., mathematica) does.

                  I don't consider mathematica a programming language. It's a software program.

                        Tough. Every single language with a symbolic math package strong enough to represent .999 repeated will confirm that it is equal to 1.

                        • Yes, and if you add up the number of real-world applications that use such languages you'd probably get a list of two or three.

                          • Doesn't Java have a symbolic math package?

                            • Language != Framework.

                              And no, as far as I know there's no official one.

                              • Look, since we agree that .999... = 1, we can either:

                                a.Call the proposition 'Proven'

                                or

                                b. We can say that the proposition is 'Defined to be True'

                                Why should I prefer 'a' (proven) to 'b' (defined) when the proofs provided introduce serious unsolved problems of logic
