Template:Fraction/doc

Template:Documentation subpage 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+B⁄C (integer, numerator and denominator)

<span class="frac">A<sup>&nbsp;B</sup>⁄<sub>C</sub></span>

{{frac|A|B}}

A⁄B (numerator and denominator)

<span class="frac"><sup>A</sup>⁄<sub>B</sub></span>

{{frac|A}}

1⁄A (denominator only)

<span class="frac"><sup>1</sup>⁄<sub>A</sub></span>

{{frac}}

⁄ (fraction slash only)

<span class="frac">⁄</span>

Parameters

A template for displaying common fractions of the form int+num/den nicely. It supports 0–3 anonymous parameters with positional meaning.

Template parameters

Parameter		Description	Type	Status
1st part from left	1	Denominator if only parameter supplied. Numerator if two parameters supplied. Integer if three parameters supplied. If no parameter is specified the template will render a fraction slash only.	String	optional
2nd part from left	2	Denominator if two parameters supplied. Numerator if three parameters supplied.	String	optional
3rd part from left	3	Denominator, always.	String	optional

Deactivation and customization

Users who prefer to see fractions inline, e.g. "1 2⁄3" instead of "1+2⁄3", 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

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