| The latest version of GNU Taler shows both "available" (as seen in Balances, the sum of coin values) and "sendable" (= available minus fees), which is the largest amount that could be sent.
But you're right, the error message "amount too small" makes no sense.
While the smallest coin depends on the denominations the Exchange uses, you could always try to send less if you were able to enter (depending on the currency specs) an amount smaller than the smallest denomination, and the Exchange would just take the difference as sender fee - making you pay at least the smallest denomination, if not more.
Of course, the receiver wouldn't get anything out of this transaction - since the transferred amount is smaller than the smallest denomination, the Exchange would just round the received amount down to zero, booking the difference as receiver fee...
I removed this error completely. |
