Hold on, thar...
.111..., carried to infinity, IS 1/9, and
.999..., carried to infinity, IS 1.  There is no roundoff error in infinite
decimal expansions.

Even in the computer world, the equality sometimes holds: for example, in
APL, a "fuzz" is applied to output results (although not for intermediate
ones).  If you type in enough 9's, it will echo "1".
