(Worded "Why do many electronics operate on 5 AND 3,3 Volts?" in case it gets edited.)
Recently reminded me of the frustration of working with electronics on an international scope. Some countries use period/full-stop for the decimal mark, others use the comma.
I read up a little on this at Wikipedia:
"International" languages like Ido and Esperanto favor use of the comma for the decimal mark. I was surprised by this, because I find the comma more distracting in numbers when reading with text.
In any case, my question/proposal is thus:
Does StackExchange (specifically EE) have any preference or standardization when it comes to the decimal mark? Which is ultimately more common? (Obviously I would be biased if I said the period/full-stop seems to be more common, as I am in the US.)
Should SE/EE standardize on one or another, so as to not mix formats?
