See the thing about using real numbers is that they work. Physics works, biology works, space stations work and the computers that you use work, to allow to post dumb shit about how real numbers don't work.

If you guys want to say that real numbers don't exist and there are no numbers bigger than 100, fine. But early on people realized there is use in defining things like "reals, convergence, imaginaries" because it allows to do stuff that we couldn't without them like calculus which is used everywhere today. And this led to what are known as geometric series, as in, $\sum {\frac{9}{10^n}}$, which can be evaluated with this new, interesting, mathematical framework (outside of just naturals) to 1. As a shorthand we sometimes use 0.999... to denote this sum.

Sometimes people who don't understand the more advanced math system think that 0.999... is like a process of adding on the digit 9 to the decimal number 0.9 and can never be really completed. This leads them to the incorrect conclusion that 0.999... isn't 1.

I recommend that such people either take a basic calculus course in highschool or take a basic real analysis course in university.
