Seriously though the comma makes a lot more sense to me. Periods are normally used to end things in most western languages, and admittedly to separate things, but they have a far more conclusive connotation to them, imo. Whereas commas are always used to separate things, but never to end them.

I mean, fuck, look at my sentences. Commas are used to separate minor things (clauses), while periods are used to separate major things, (sentences).

Calculators here are not adapted, so they almost always use a dot. However, some software (on phones or computers) is 'smart' and requires a comma. Which, in turn, is not available on the numpad of these devices.

You just gave the reason TO use a period. Period separates the hard end of whole number and faction, comma just acts as a loose separator of millions, billions, trillions to quick gauge the size of the number for the reader. Spaces should show the end and start of different numbers in a sequence.
