This is a more serious question than English speakers may realize. That period on your numeric keypad isn't a physical period, it's a "decimal separator" which may be silently replaced by a physical comma if you've got a non-English operating system. (By weird coincidence I have just this instant come from posting about games. It was a game-registration-code problem that first led me to the decimal-separator explanation.)
