The preferred separator in French is a non-breaking space, so it in fact would be 1 000,01. But that is irrelevant because this article is not in French. It really should read 7,207 images per second, which incidentally is the name of the video in the original article.

One very "good" application to learn these things is Microsoft's Excel. It fully implements regional settings, so if you want to open/save a .csv file, it will automatically use the list separator for your country as the field separator. If the .csv is a "normal" comma separated file, and your regional list separator is set as semicolon, tough luck. You can still open them with the advanced "something-separated" wizard, but it's manual. Also, if you type a formula you just found on the 'net that looks like =CONCATENATE(A1,B1) it will not be recognized because you still have to use the regional list separator, so you need =CONCATENATE(A1;B1) to work.

In that case the title should be in French and should say 7.207,00 right? :)
