Richard, in some European countries, people use comma(,) instead of point(.)to represent the decimal symbol. You might have come across here on italki some people using comma instead of point, it made me confused when I encountered this difference:)

I only count four names, Richard: "period," "full stop," "dot," and "point." What is the fifth name?

# is called "pound sign," "number sign," "hashtag," and "octothorp."

/ is called "slash," "solidus," "virgule," "front slash" (to distinguish it from "back slash"), and often, when used to indicate a fraction, read aloud as "over."
