Don't use int for money. Use BigDecimal.

I know performance is an issue, but you can always find non-hackish solutions: like a memory upgrade from management, because you're writing safe, clean code :-)

BigDecimal uses 10 times as much memory as an int but I didn't intend to properly model currency amounts anyway.

Any sane developer will track money in lowest units - eg cents. Rather than Dollars.

A sane developer is as rare as a sufficiently smart compiler.
