Strange PPL error

[Tim Wessman]

The problem was that we had to make it so "a math teacher could type some program functions in" since that was becoming something in math curriculum in Europe. It was decided that this meant it had to work using the current settings, and be recognizable...

Did not really want to do it, but when the decimal separator was something else, and the numbers suddenly no longer matched, it was decided by the powers that be that the solution was to make it accept 123,456 if you were in a place that uses that.

Not great, we did not particularly want to do it because it made things more complex, but there you go. That is the reason.
