TIL that it is convention in the English language to place the euro sign in front of the amount and not after it, like in most other European languages.
NumPad currently accepts numbers in the "9,999.9" format, which is the default in the anglosphere, but "9.999,9" is common elsewhere. So that's another thing I'd like to address in the future.
(I'm European too and I thought it was always in front, everywhere)
