Template:Frac/doc

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)

<source lang=html5>A ^B⁄_C</source>

{{frac|A|B}}

​^A⁄_B (numerator and denominator)

<source lang=html5>^A⁄_B</source>

{{frac|A}}

​¹⁄_A (denominator only)

<source lang=html5>¹⁄_A</source>

{{frac}}

​⁄ (fraction slash only)

<source lang=html5>⁄</source>

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

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

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: <source lang="css">.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 */;

}</source>

Code

<source lang=html5> ⁄ </source>

Notes

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