It depends where in Europe ;) Switzerland, Liechtenstein and United Kingdom use decimal point.

In Romania the comma should be the decimal separator in theory.

In practice my online banking uses the dot, and doesn't accept commas anywhere. And it's a Romanian bank with a homemade web interface.

I just checked 3 random paper receipts i had lying around (from different stores), two use the comma and one the dot.

The French, on the other hand, religiously use the comma as a decimal separator.

In Switzerland we mostly use the format 12'345'678.901

Obviously I'm biased but I think it's the best system because there's no room for confusion.

But you do use a decimal point. Liechtenstein uses exactly the same format.

Interesting! Does it differ in different languages? I assumed German Swiss will use the same system as Germany, French Swiss the same in French, etc.
