Money Class?

[Lukas Bradley <lu...@somnia.com>]

I'm running (back) into the age old question of representing monetary 
values in Java.  Should I use a float and risk floating point errors, 
should I use int and hold cents (or pieces of the currency) or should I 
create a Money Class to handle both of these problems but create bulkier 
code?

Has Commons approached this?  I don't need a fully I18N solution, I just 
need something that will allow for addition, subtraction, and 
calculation of percentages.

Any help or advice appreciated.

In my experience floating point errors are not a "risk", they are a 
"certainty".

I've never had an occasion to try it, but I've always thought that 
java.math.BigDecimal would be good choice for representing money.

Hope this helps,
