Note: the former {{fraction}} template is now {{frac}}.
This template should not be used in mathematical articles.[1]


The {{fraction}} OEIS Wiki formatting and function template shows either mixed fractions or simple fractions (also known as a common fractions or vulgar fractions) in an alternative form. It takes one, two or three parameters: the optional integer, the optional numerator and the required denominator; in this order. Please don't substitute it.

Usage

{{fraction|A|B|C}}

BC (integer, numerator and denominator of a mixed fraction) (integer may be signed with {{op|-}})

{{fraction|A|B}}

AB (numerator and denominator of a simple fraction) (numerator may be signed with {{op|-}})

{{fraction|A}}

1A (denominator of an Egyptian fraction, which is a special case of a simple fraction)

Notes

  1. In mathematics articles, fractions should always be written either with a horizontal fraction bar (as in 
    1
    2
    , with {{math|{{frac|1|2}}|&}}), or with a fraction slash ⁄ ({{sym|frasl}}) with the baseline of the numbers aligned with the baseline of the surrounding text (as 1 ⁄ 2, with 1 {{sym|frasl}} 2). The use of {{fraction}} (such as 12, with {{fraction|1|2}}) is discouraged in mathematics articles. The use of Unicode symbols (such as the vulgar fraction ½, with &#x00BD;) is discouraged entirely, for accessibility reasons among others. Metric units are given in decimal fractions (e.g., 5.2 cm); non-metric units can be either type of fraction, but the fraction style should be consistent throughout the article.
