There seem to be a lot of people here asking questions that show a gross misunderstanding of the concepts involved. I think someone's trolling. There's only so many times you can repeat that 0.99... is 1 because that's how real numbers work before every idiot grasps it, going beyond it is just trolling, pure and simple. Please keep this in mind when replying to correct the n-th poster who seemingly is either eight years old or didn't read any of the precending comments.
