With money though it quantizes at the cent mark, so it never gets to
an infinite
string of 9s.

But with the decimal system, an infinite repeating decimal like
0.9999.... is
*defined* as the *LIMIT* of the sequence

0.a, 0.aa, 0.aaa, ... (0 <= a <= 9)

So here's a question: What is the LIMIT of

0.9, 0.99, 0.999, ...

?

By *definition*, that is the value of 0.9999..., OK?

It would take an infinite amount of time then to get $1,000,000 if
paid according
to your scheme. Just as to get 1/3 of that amount, paid off in
installments of $300,000, $30,000, $3,000, $300, $30, $3, $0.3, $0.03,
$0.003,
etc. would.
