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 not be used in science or mathematical articles, per MOS:FRAC and MOS:MATH#Fractions; use {{sfrac}} instead. To allow numerical sorting of a column containing fractions, use {{sortfrac}} instead. It is a combination of this template and {{sort}}.

{{frac|A|B|C}}
APage Template:Screen reader-only/styles.css has no content. BC (integer, numerator and denominator)
<span class="frac">A<sup>&nbsp;B</sup><sub>C</sub></span>
{{frac|A|B}}
AB (numerator and denominator)
<span class="frac"><sup>A</sup><sub>B</sub></span>
{{frac|A}}
1A (denominator only)
<span class="frac"><sup>1</sup><sub>A</sub></span>
{{frac}}
(fraction slash only)
<span class="frac"></span>

Deactivation and customization

Users who prefer to see fractions inline, e.g. „1 2⁄3“ instead of „​1Page Template:Screen reader-only/styles.css has no content. 23“, can turn off the effects of this template by adding the following code to their user stylesheet:

.frac>sup /* numerator */,
.frac>sub /* denominator */
{
  vertical-align: inherit/* or baseline*/;
  font-size: inherit/* or 1em*/;
  line-height: inherit/* or 1*/;
  position: inherit/* or static*/;
}

Code

<span class="frac nowrap">{{#if:{{{3|}}}
 |{{{1}}}<sup>&#32;{{{2}}}</sup>&frasl;<sub>{{{3}}}</sub>
 |{{#if:{{{2|}}}
  |<sup>{{{1}}}</sup>&frasl;<sub>{{{2}}}</sub>
  |{{#if:{{{1|}}}
   |<sup>1</sup>&frasl;<sub>{{{1}}}</sub>
   |&frasl;
  }}
 }}
}}</span>

Notes

  • &frasl; may be used to print out the fraction glyph " ⁄ "

See also

  • {{1/2}} (​12), {{1/3}}, {{2/3}}, {{1/4}}, {{3/4}}, shorthands
  • {{fraction}} (​12), only uses precomposed glyphs, which usually is not preferred due to accessibility concerns
  • {{sfrac}} (Template:Sfrac), displays common fractions using a vinculum, which is preferable for scientific and mathematical articles.
