Growing up in Switzerland with a dot as the decimal separator, I newer knew just how much of an outlier we are in this part of the world until now.

We also use apostrophe as the thousands separator, so: 1'234'567.89 which I personally always found much more readable that using commas and dots. Is there any other country that uses this combination?
