Hi Burr, in some other countries (for example France), the decimal digit separator is the comma character and not the period character like you are used to.

So for example in some countries they write the number "two and a half" in decimal form like this: 2,5


When your regional settings in Windows are set to use the comma character as the decimal separator, then you can enter in values like that into MoI.


See here for more details than you would want to know ;)
