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}}
A BC (integer, numerator and denominator)
{{frac|A|B}}
AB (numerator and denominator)
{{frac|A}}
1A (denominator only)
{{frac}}
(fraction slash only)

Deactivation and customization

Users who prefer to see fractions inline, e.g. "1 2⁄3" instead of "1 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}}}<span class="visualhide">&nbsp;</span><sup>{{{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

  • {{frac}} or &frasl; may be used to print out the fraction slash glyph " ⁄ ".
