Display prices in German format

[Jurist]

Hello,

Is it possible to change the way the prices are displayed? In fact, it would need to change every number on the website. 

For example: 10000, should be 10.000. I know that in theory I could develop a module that would just edit the price string and add a dot between the numbers, 3 places from the decimal dot, however it would be tedious as I would need to make sure every single number is taken into consideration.

Is there some system solution to that? If not to every number, maybe just for prices?

Thanks
