We're talking quadrillions here, people. That's even beyond the
federal deficit! What's the need for such big numbers? I could never
figure out why credit card companies needed 16 digits, except for
Amex, which seems to get by with just 15.

:-)
just think about Turkish Lira and having to deal with large currency trades
in this specific currency (or before the Euro: Italian Lira). There're
applications where 15 digits are not enough :-)
