Commercial minus sign


The commercial minus sign is a typographical and mathematical symbol used in commercial and financial documents in some European languages, in specific contexts.
In some commercial and financial documents, especially in Germany and Scandinavia, the commercial minus sign is used to signify a negative remainder of a division operation. The symbol is also used in the margins of letters to indicate an enclosure, where the upper point is sometimes replaced with the corresponding number.
The Uralic Phonetic Alphabet uses commercial minus signs to denote borrowed forms of a sound.
In Finland, it is used as a symbol for a correct response.

Typographic variant

In Germany, the form may be seen informally as a convenient alternative to the formal glyph, since this may be typed directly from the keyboard without recourse to unicode input.
