When you deal with monetary amounts, you really should not use floating point numbers. In VA Smalltalk, there's AbtMoney:

one := 3.54 abtAsMonetaryAmount.
two := 2.12 abtAsMonetaryAmount.

one + two an AbtMonetaryAmouny

If you try the above code, you'll find that you can do standard arithmetic with money objects. If your applicatio deals with financial data, use this instead of floating point :)
