Does 1,9999...=2?

What about 0,4999...=0,5 or 0,00...(infinite zeroes)...1 = 0?

The argument that 0.499... is the same as 0.5 is the exact same argument for 0.0....1=0. Since: 0.5-0.4999=0.0...1 if you say that 0.5 and 0.4999... are the same then 0.0...1 and 0 are the same. (same for 2 and 1.999...).

You just need to understand that 0.0...1 is so small that in reality it is 0.
