BTW: I think we could after a bit refactoring adopt you decimal class for upp. It's the only missing type of Value right now IMO.
I wonder whether this is implementation is a good tactics.
E.g. .NET seems to implement decimal as 128bit FP number with decimal exponent.

Well we can start with anything. Implementation can be always changed. What I wanted only to say Decimal type would be very useful (+ plus EditDecimal, EditCurrency...)
I am not sure that it is that easy.... Chosen implementation will have a big impact later.
