German: I hate that we use comma as a decimal separator. Makes working with international documents a hassle, my numpad on pc makes a comma so I cannot even type a date.....we like to complain about us imperial units as much as anyone but our comma is almost as stupid!
The funny thing is, that most of the world uses commas as decimal separator and comma is the preferred decimal separator by ISO. But instead, in English speaking countries, the period is used as the decimal separator. Actually it comes from the original decimal separator, that was used in the British Empire called ⟨·⟩. When they were changing units to metric, ISO didn't recognize interpunct as a decimal separator, because it was too similar to the multiplication sign used in other countries. So after some debate in the UK, they've adopted the period, because the US was already using it. From the British Empire, South Africa instead adopted the comma.
I did not know that. Very interesting, thanks. Not so fun fact: Switzerland, although German speaking, does not use the comma. Also their keyboard Layout is all over the place with German French and Italian influences.
