This is, indeed, an example of a field that probably does need to
be able to vary substantially from "2 decimals precision."
I'd almost think that the price field should be represented as
two int values, those two values being treated as a fraction.

It somewhat annoys me that the markets are moving to "decimalization"
when the traditional "powers of 2" units (8ths, 16ths) are so wonderfully
convenient for use with binary operations. After all, 0.1 decimal works
out to, in binary, 0.00011001100110011... (with repeating sequences after
that), which is precisely why decimal floating point calculations head
"off" fairly quickly.

(The Even Cooler Idea would be to use continued fractions, but everyone is
*certainly* allowed to trash that idea as ludicrously impractical... That
only works if we rewrite the whole thing in CL :-)).
