Even with no regard to Tristram Shandy who disproves actual infinite,

we can say: The sequence for 1/9 = 0.111... cannot have indices that

differ from all indices of its finite approximations. So you cannot

distinguish 0.111... by looking at digits from its finite

approximations. And you cannot use it in any discourse because every

message is finite and needs an endoffile signal to be meaningful.

Concluding: The property that a sequence of digits does not end cannot

be obtained from its digits. (Remember, 0.111... is not a sequence of

digits but is only a rule to construct a sequence of digits. The rule

yields the sequence, but the sequence does not yield the rule.)

That means in mathematics, understood as discourse, there is no

decimal representation of 1/9. What God may use for his mathematics is

not my problem.

Thank you for that question.
