It wouldn't in any system that is coherent or consistent. If you change 1 to .9999999999... which is = to 1 and do .99999999999...+.999999999999... you get 1.9999999999999999.... and if you round...
There is only one one in one one, but there are two ones in eleven. And there are no "ones" in one one if you are counting the "s". so there is one, one in one :)
