DAE get annoyed when commas (,) are used instead of decimal points?

I grew up somewhere in Asia and went to American school during my formative years, so using decimal points is the way to go for me.

I've now moved to Sweden and here we use a comma to denote any partial value smaller than one.

The thing is that I use Excel quite often and it annoys me to have to go through my equations again because of the change up between comma's and period's.

DAE have such an experience or is it just me? Additionally, what sort of small things have annoyed you a little in your new environment.
