I've noticed that various applications use various number of decimal places in their implementations.
The bitcoin-qt client uses eight, which is what I've been following in my development, however some use less. Also, some clients use rounding, some use floor. This lack of consistency makes it difficult to implement a correct check of the expected balance of an address, because sometimes amounts may be slightly off. If I'm requesting to be paid to eight decimal places and a client only pays accurate to two because that's what their client supports, and my value gets rounded down, the customer will be missing .00XXXXXX bitcoin so they technically 'haven't paid'. I know it's only by small amounts, but if I end up using the 'lowest common decimal place' then the rounding errors could get really pathetic.
Can the community please pick a standard and go with it? Have your say here.
I think we should be using eight decimal places, rounded...
