> Numbers with a dot or comma means it's decimal.

But... It doesn't in IP addresses, version numbers, dates, with different locales, and possibly many other uses.

These examples clearly show that "numbers with a dot" doesn't always mean decimal.

A dot is a dot. Mainly with the _role_ of a separator. When you interpret it, it might mean a _decimal_ separator for you, but as well might mean a thousand-separator for MS excel with the German locale.

>Your date reference makes no sence because either / or - is used in those cases, not dots or comma's.

In my (european) country a dot is used - for example 5.11.2023.

That depends on the country. For example, in Japan it is very common to write dates with either a dot, or with the full kanjis for year, month and day.

Good point, the system would work just as well if it was something like:

w36:2

But it wouldn't cause nearly as much confusion or decimal place issues relating to improper automation.
