Re: Locale dependent description too
That's pretty normal when you use comma as the decimal separator – as the entire continental Europe does. Occasionally someone calls them SSV or something, but it is hardly less confusing because few know what it means. And anyway, a ‘CSV’ found in the wild can be separated by tabs, spaces or whatever else was at hand… Do not trust the extension.
When you see 3,141, it can be any of these:
two numbers 3 & 141
an approximate value of π
1000× an approximate value of π
The joy of international number formatting.
