I presume from your example, you mean we need to use arbitrary
precision/rationals rather than just integers since in your example,
the cost was actually 33 1/3, which isn't representable as an integer.
If so, then that would be fine with me, but it's a much bigger change
than just trying to get things right on the scale I was suggesting,
and since we're using doubles, it doesn't seem to be a big deal, at
least in a case like this, though I definitely get your more general
point.
If we do decide we need to do something other than doubles, I suspect
we should just switch to gmp and forget about it. It's well deployed,
apparently extremely fast, well designed, and I hear has some really
smart people behind it...

Description: Multiprecision arithmetic library
GNU MP is a programmer's library for arbitrary precision
arithmetic (ie, a bignum package). It can operate on signed
integer, rational, and floating point numeric types.
.
It has a rich set of functions, and the functions have a regular
interface.
