General Decimal Arithmetic

Once I surprised one of my clients telling them that they should be careful using floating-point arithmetic (double type in Java) for financial calculations. In fact, it's surprising that this was a revelation to them :) C'mon, we've been working on a financial application.

I thought that Java's BigDecimal was inconvinient, due to its limited functionality. Now I see that IBM works on this issue in Java as well as in general computing.
