I tried to clear up some of these issues during the Nodebo hackfest, but:

1. coming from a locale which uses the NORMAL "." as decimal
separator, I have no idea what the expected/proper behavior should be
for locales which use ","

2. no-one I asked from these locales could even give me a definitive
answer about what the correct behavior is

So I quickly decided to let someone else handle this mess ;)
