An obelus (symbol: ÷, plural: obeli) is a symbol consisting of a short horizontal line with a dot above and below. It is mainly used to represent the mathematical operation of division. It is therefore commonly called the division sign.
Uses
The obelus is occasionally used in Polish language typography to represent ranges (such as the range 1÷10).
As of 2007, it was also used to indicate a range in Italian documents (for example, 40% ÷ 50% would indicate 40 percent to 50 percent).[citation needed]
The obelus is primarily used as a symbol for division (as on a calculator) and as an operator in elementary arithmetic. Division is also signified in other ways — usually as a fraction: by writing the operands one above the other and separated by a line, or on the same line separated by a solidus or slash.
In many non-Anglophone countries, the colon is used as a division sign: “a divided by b” is written as a : b, and this is widely used to indicate a ratio.[citation needed]
In Microsoft Windows, the obelus is produced with Alt+0247 on the number pad or by pressing Alt Gr, Shift and the "+ =" key. In Mac OS, it is produced with Option + / (Option + slash).
On UNIX-based systems using Screen or X with a Compose key enabled, it can be produced by composing : (colon) and - (minus), though this is locale- and setting-dependent. It may also be input by Unicode code-point on GTK-based applications by pressing Control + Shift + U, followed by the codepoint in hexadecimal (F7) and terminated by return.
In the Unicode character set, the obelus is known as the “division sign” and has the code point U+00F7. In HTML, it can be encoded as ÷ or ÷ (at HTML level 3.2), or as ÷.
In LaTeX, the obelus is obtained by \div.
