模板:Fraction/doc

模板:No subst 模板:Info This template builds an alternative form of common fractions. The template takes one, two, or three parameters: the optional integer (may be signed), the optional numerator and the required denominator; in this order.

Please do not subst:itute it. This template should also not be used in certain situations; see MOS:FRAC and MOS:MATH § Fractions. For science or mathematical articles, use {{sfrac}} instead. To allow numerical sorting of a column containing fractions, use data-sort-value="X.YYY" where X.YYY is a rounded decimal equivalent. See Help:Sorting for more information and options. Inside citation templates, use the cleaner {{citefrac}}.

{{fraction|A|B|C}}

A+B⁄C (integer, numerator and denominator)

{{fraction|B|C}}

B⁄C (numerator and denominator)

{{fraction|C}}

1⁄C (denominator only)

{{fraction}}

⁄ (fraction slash only)

Examples

Numbers

1⁄2, 1⁄3, 2⁄3, 1⁄4, 3⁄4, 1⁄5, 2⁄5, 3⁄5, 4⁄5, 1⁄6, 5⁄6, 1⁄7, 2⁄7, 3⁄7, 4⁄7, 5⁄7, 6⁄7, 1⁄8, 3⁄8, 5⁄8, 7⁄8, 1⁄16, 3⁄16, 5⁄16, 7⁄16, 9⁄16, 11⁄16, 13⁄16, 15⁄16

Units

m⁄s, km⁄h, kg·m⁄s², 1⁄s, Mbit⁄s

Notes

• {{fraction}} or ⁄ may be used to print out the fraction slash glyph " ⁄ ".
• For mixed fractions, in some contexts a "+" is generated between the whole number part and fraction part. If this is not desirable, put the whole number part outside the template, and put a non-breaking space between when the spacing is desirable. For example: "33 {{frac|1|3}}".

Parameters

This is the TemplateData for this template used by TemplateWizard, VisualEditor and other tools. See a monthly parameter usage report for Template:Fraction in articles based on its TemplateData.
