Hi Mike

I believe that in .NET 3.5, you will have the ability to apply additional methods to .NET base classes for just the kind of requirement you specify (not dissimilar to Ruby or adding a new method to a JavaScript prototype).

Right now, I would say that creating a custom decimal class to provide a "ToRoundedString" method is excessive.

If I wanted that, I would probably just create a static method in a helper class:-

// Numbers is the class name containing the static method ToRoundedString()
// You could put all of you number related helper method in this class.
Numbers.ToRoundedString(myDecimalVar)

For example, if I find I am rounding decimals a certain way many times, would it be advantageous to create a custom decimal class with a .ToRoundedString method? Would I then want to use this derived type in place of all decimal types in my application?
