what decimal separators are in use around the world? (I have a few places between programs where I must exchange a floating point number as a string without a thousands separator.) yes, I know this isn’t a fantastic idea…there are many ways this could be done but more serious improvements will need to come later…
I know of “,” and “.” but are there any others?

There you have a list of separators (basically “,”, “.” and ” ” in writing and also “‘” and “˙” for handwriting), with many examples of all of them in different countries.
Since this is applied to programming, you should only worry about “,”, “.” and ” “, that is, unless you are doing some OCR’ing.
