iOS Question Calculations with comma value

[JonPM]

I have a calculator app which allows for decimal number input only. The problem is that some devices (depending on locality) use the comma instead of a period for decimal point. So currently if the user uses ',' as the separator my app returns 0 as answer. What is the best method of performing arithmetic on inputs that use comma?

The easiest way will be to replace the comma with a dot:

s = s.Replace(",", ".")
