AddItUp sums a lot of numbers considering a custom defined decimal separator. The "," and "." are the two default ones which you can easily switch at a press of a button. But you can easily use any other decimal separator character or a group of decimal separator characters like ",,", "..", ",,;", "..;", ";" etc. Each number should be entered on its own line. You will also know when a line holds a value which cannot be converted to a number.
