However, none of this seems to deal with the major problems with the money type right now: - Only supports one currency (dollars) - Only supports one scale (yen has no decimal normally, but what if you want to track hundredths of a dollar-cent?) My question, what is this Money64 type buying you over just storing an integer in your database? There should be some value-add somewhere, but what is it? I've written applications tracking money using just an integer, if there were a special money type, I'd expect it to do something more.
