> Conversely the English 1,000,000 is 1.000.000 in German! Very confusing.
Well, yes. But it's mostly the Anglosphere being weird again: https://commons.m.wikimedia.org/wiki/File:DecimalSeparator.s...
I personally like to use thin spaces or apostrophes as a thousands separator, precisely to avoid the language confusion. I also try to avoid three decimals going for 2 or 4 instead, but you can't always do that, because it changes the content.
> Remember Germany is still the place where you say four-and-twenty for twenty-four …
As someone from another language that does that: agreed. It gets even weirder with 124: one hundred four and twenty. Middle-endianness is silly.
