Decimal point ↔ Comma

Sometimes the data you have uses another decimal mark than the programs on your computer use. This app replaces all decimal points (.) with commas (,) and all commas (,) with decimal points (.). The Physik-M apps always use decimal points (.) for the decimal mark. Do not use commas.

You could also copy the data to a text editor and use the replace function to exchange between the two formats.
