You probably don't need a decimal arithmetic class. What you need is
decimal fractions, which are just a special case of the good old
Fractions found in every self-respecting Smalltalk. With these,
arithmetic using +, -, *, / is exact (which is probably what you're after
anyway).
You might want to implement a special number class which does the right
kind of displaying and denominator fudging.
Every single case of decimal arithmetic that I've seen (ok, it's just
one: VisualAge...) is unnecessarily complicated, slow and limited. Why
would you want to have that?
Back in the good old COBOL days, BCD number representation had a place
since programs were I/O dominated anyway. But nowadays it's just
nonsense.
