> In the german speaking regions, the apostrophe is generally used for this The apostrophe (') as delimiter for 3-digit groups is partly used in Switzerland. In Germany we use periods (.) as delimiter. >On the other hand, the Germans seem to use commas as decimal marks, which is even sillier. For me decimal marks are more important than digit group delimiters. And a period (.) is smaller than a comma (,). Thus we use a comma for the more important features of numbers. This is how I explained it to me in school. Of course, as a programmer, I'm pretty muched used to periods as decimal marks now. Edit: Add two sentences.
