So, it doesn't actually use that value, amusingly enough. It likely uses the real value. It's only what it shows you. Ever try to withdraw *exactly* how much BTC it says you have? Won't let you -- says you don't have that much, because in reality, you don't. You're trying to withdraw 3 Satoshi (the lowest possible division of a bitcoin) more than you really have or something.It's only what displays that's inaccurate. I agree though, more precision wouldn't hurt or anything.
