[desperately] Maybe this is from some country where they use commas as decimal points, and also as digit separators after the decimal, and also use random other characters for decoration???

I'll be honest: It's complete insanity to use commas within a number. If you need laughably high precision, use spaces for readability. If you need a lot of zeros, use power notation.

There is no excuse for putting commas in a number. I rest my case.

Depending on handwriting or font, commas may be more visible than spaces.

Hard disagree. I work a lot with numbers, both hand-written and typed. I've yet to come across a situation where spaces are not sufficiently clear for readability. Using spaces for separation has never been an issue with letters, why would it be an issue with numbers?

the problem with spaces is that it leaves it ambigous whether it's one or multiple separate numbers, whereas a non-space separator (i think apostrophe is just obviously the best) makes it clear: 123'000'398
