This is very interesting. I agree that some of the formatting puzzled me as well. I would assume this follows some standard even when the use of said standard is uncommon. I have for example not seen 1.000,00 € used, but I thought that perhaps if you live in Germany, France, or another EU country then it is common.
I do not have much, if anything to add, other than saying, “What @silas@programming.dev said.” - Great advice.
Amen to that :) We have to start somewhere though, right :)
