I completely understand wp's point of view and your analysis is completely accurate. In Venezuela all PCs are configured with the comma for the decimal part and it happens that out of habit, 100% of the users got used to typing the decimal point when they use Excel, and it places the comma automatically, and it is difficult for them to understand that In the case of software developed with Pascal, not to mention other languages, they must type the comma and not the point in the decimal part, most people assume that for any software it is how Excel does it.
For this reason I wanted to try to ensure that the behavior that is natural for people, such as in Excel, is the same in the software I develop.
