Glyph origin

[edit]

Use as a multiplication or product operator is usually attributed to German polymathGottfried Wilhelm Leibniz. On 29 July 1698, he wrote in a letter toJohann Bernoulli (translated byFlorian Cajori):[1]

I do not like× as a symbol for multiplication, as it is easily confounded withx; [] often I simply relate two quantities by an interposed dot and indicate multiplication byZC ·LM. Hence, in designating ratio I use not one point but two points, which I use at the same time for division.

Usage notes

[edit]
  • (decimal point): Many Britons employ the American decimal point ⟨.⟩ owing to a general lack of support for the middot character on computers. It remains common in writing done by hand.
  • (addition compound): The IUPAC Recommendations for Nomenclature of Organic Chemistry[2] state: “Centre dots in formulae of (formal) addition compounds, including hydrates, adducts, clathrates, double salts and double oxides, separate the individual constituents. The dot is written in the centre of the line to distinguish it from a full stop (period).”

Synonyms
