I’m obviously biased since I grew up with this “9,81” being a decimal, but in my head just thinking about it, it also makes sense. As you can see in these sentences, a comma is a break in a sentence, while a dot ends a sentence. Then again, math gets really messy when you have horizontal vectors with decimal numbers in-between, so maybe the dot is actually better idk. Eg: (2,3 , 4,5 , 3,7)
