There should be no argument. 0.9999... = 1. They're the same thing. Red is red. Blue is blue. Water is water. 0.999999... = 1. Take an Introductory Analysis class, where "infinity" is treated rigorously so that some of you "logicians" can't make up weird, subjective arguments.

The funny thing is that the people trying to dispute it are taking a condescending attitude, as if they know better. If you're going to go against the established knowledge in mathematics, of all things, then at least be humble about it.


If your referring to me I'm not being condescending at all.  I respect Math

that being said there is room for error in all things.  I'm simply saying if mathematically you can make something something it's not on an infinite scale it is probably a reflection of human understanding not being able to properly understand infinity or how math would even work on an infinite scale

And ironically you enter the thread shouting things like calling people "logicians" and their opinions weird but then go on and say act humble.  Look in a mirror

Chill man, I wasn't reffering to you, but to somebody else, MDMAlliance to be exact. I do agree that I sounded arrogant and condescending but it was a reaction; you guys should understand that it's fine to doubt something until you're shown proof, but to claim the opposite of something that is well known and understood in mathematics after being told so that the thing is well known makes you look infinitely (yes I use this word on purpose) more untolerable than, say, flat Earth people.

If you're this desperate to see rigorous proof, check out the book Principles of Mathematical Analysis by Walter Rudin. It's a rigorous introduction to analysis, and there's a whole section on deriving the set of real numbers from the set of rationals.

You may also want to check Michael Spivak's Calculus. The first chapter treats numbers basically as abstractly as you can consider for an introduction.
