For straight math a proof is a proof, and there are several different proofs that do not involve limits that show .999... = 1, and according to the rules of math are 100% true. An example would be:
x = 0.9999...
10x = 9.9999...
10x - x = 9.9999... - 0.9999...
9x = 9
x = 1.
x = 0.9999...
10x = 9.9999...
10x - x = 9.9999... - 0.9999...
9x = 9
x = 1.
