Because the issue here is not to press a comma instead of a period. The issue
here is that if you calculate =3/2 LO returns 1,5 no matter what and there's no
way that I know of to get 1.5 instead. At the same time, there's no way to get
1.5 (entered directly in a cell) recognized as a number instead of text.
