I've got a question- a friend of mine works in IT and has asked some help with communicating with some of his international clients. He's specifically asking about Portugal and Germany.

The question is what a "." is called in those regions. In American English it would be a period. In British English it would be a full stop. A lot of people just call it 'Dot'

Any help is appreciated.

@Surasanji I'd be curious to hear the answer to that too. But more importantly keep in mind the period and the comma have reversed meaning WRT numbers in much of Europe too. So they would write like this "That thing is 1.000,58 meters long."
