I was idly speculating yesterday about letting the Ryu code print
the division result, so that we get a variable number of digits.
Realistically, that'd probably result in many cases in more digits
than anybody wants, so it's not a serious proposal.  I'm cool with
the fixed-two-digits approach to start with.
