If the remaining balance after sending a transaction would be less than 0.01, the subcent remainder is also being sent with the transaction.
Example:
If I have 10.00946786 BTC in my wallet and I send 10 BTC as a transaction, it will actually send all 10.00946786 BTC and not leave the subcent amount.
This is a feature to prevent the remaining 0.00XXXX from being lost as you can't send that without a 0.01 fee which you can't have if your balance is <0.01
Yes, but if I have 10.01999999 bitcoins, and am in a pool, I could safely assume that I would be able to make 0.00000001 bitcoins to then have whole cent within a reasonable amount of time. The feature should be to simply not allow you to send a transaction if you have less than 0.01 rather than sending it along with the whole cent. Otherwise, it's theft of coin (negligible or not) by the network.
You cannot send a coin smaller than 0.01 without paying a transaction fee. So if you had a 10.019, and you got a 0.001 payment (whoever sent that would have had to pay a fee), you cannot resend that 0.001 payment without paying a 0.01 bitcoin fee. I know it looks like you have exactly 10.02 BTC in that case, but to bitcoin you have a 10.019BTC "coin" and a 0.001 BTC "coin".
In that case, it should notify users that, if they have a balance of 1.01999999 and they send someone 1 BTC with a 0.01 TxFee, they are sending them their subcent balance with it.
Yep, the GUI should definitely notify the user, so lets keep this issue open until that is fixed.
I believe the current Qt GUI behaves correctly now.
Nope, bitcoin adds the fee at most, nothing more.
