FYI Jackpot devs, your COIN value in the source code is off.
It's impossible to move/transfer/send less than 100 satoshi. Ir rounds it off. We had a user today who had a ton of withdrawals held up because his account had insufficient funds, as he bought for example 10,000.00000008 JPC, but the system rounded it off to 10,000.000000 JPC.
He went to make a withdrawal, and the wallet complained.
We poked into the code, and the COIN value was set to 1000000 instead of 100000000 like EVERY OTHER coin.
Any value less than 100 satoshi is either rounded up to 100, or down to 0.
So, basically, JPC does not have 8 decimal places, it has 6.
Unlike every other coin out there.
Thats pretty broken.
We tried to fix it internally, but the code seems to be throughout the whole wallet, and were afraid if we changed it, it would break everything else.
Really should be fixed for a future update. Almost every single user on AllCrypt who ever bought fractional JPC has a wallet that is out of sync because the internal wallet is rounding off the last 2 decimal places.
thanks for that can someone here fix that
There's nothing to fix. Did you read the other post?
This is interesting... I don't think this matters, I did a quick research, almost all the pow/pos coins that are clones/descendant of NovaCoin are defined this way. In fact, it is defined in NovaCoin and no-one ever changed it:
https://github.com/CryptoManiac/novacoin/blob/master/src/util.hSo please check other pow/pos coins, they should all be the same.

I agree, many of the pow/pos coins are the same, and there are no issues with exchanges.
"No issues with exchanges" just means no one has noticed it, or actually CARED that the math is off, and while it's small, users are being ripped off at the exchange's benefit.
Sure, it's a small amount, but at a large trade rate, over the course of a year, that could be one heck of a lot of lost JPC. Possibly putting the exchange at risk of being insolvent. We ran the numbers. When I discovered this, AllCrypt was insolvent in JPC. Sure, it was by only a few hundred satoshi, but the wallet performs bad accounting. "Meh its not a big deal" isn't a reason to not fix it.
If our BTC accounting were off and every account "lost" a tiny amount of their BTC, no one would be saying "Whatever it's not a big deal."
Should be fixed. Regardless of the source of the bug.
