An interpunct ( · ), also known as an interpoint, middle dot, middot, and centered dot or centred dot, is a punctuation mark consisting of a vertically centered dot used for interword separation in ancient Latin script. (Word-separating spaces did not appear until some time between A.D. 600 and 800.) It appears in a variety of uses in some modern languages and is present in Unicode as code point U+00B7 · MIDDLE DOT (HTML ·⧼dot-separator⧽ ·). The multiplication dot (U+2219 ∙ BULLET OPERATOR (HTML ∙) or U+22C5 ⋅ DOT OPERATOR (HTML ⋅⧼dot-separator⧽ ⋅)), whose glyphs are similar or identical to the interpunct, is a multiplication sign optionally used instead of the styled ×: a⋅b is equivalent to a × b or "a times b". The same sign is also used in vector multiplication to discriminate between the scalar product (a ⋅ b) and the vector cross product (a × b) or exterior product (a ∧ b). As a multiplication operator, it is also encountered in symbols for compound units such as the newton-meter (N∙m or N m). The multiplication dot is a separate Unicode character (U+22C5), but is often silently replaced by the interpunct or bullet (U+2022 • BULLET (HTML •⧼dot-separator⧽ •)).
