Dario,
I'm no expert in the domain you described, but mapping your own number
classes between VW and GemStone might be a bit tricky because of the
differences in their Number class hierachies. Why not creating a class
that does the calculation on the already provided Number class of your
choice?
Hope this helps,
Adriaan.
