{{Documentation subpage}}

This template places an elliptical arc over the given text. An overarc is the notation for [[repeating decimal]]s in [[Spain]] and some [[Latin America]]n countries and for named [[Curve|geometric arc]]s.

== Usage ==
The sole, unnamed parameter is the text to place beneath the overarc. The text can be any arbitrary length and is not limited to digits. For example:

[[File:InscribedAngle 1ChordDiam.svg|thumb|right|''θ'' is the central angle subtending {{Screen reader-only|arc}} {{overarc|''AB''}} and ''ψ'' is the inscribed angle subtending {{Screen reader-only|arc}} {{overarc|''AB''}}.]]

* {{demo-inline|<nowiki>0.{{overarc|6}}</nowiki>}}
* {{demo-inline|<nowiki>0.{{overarc|81}}</nowiki>}}
* {{demo-inline|<nowiki>0.5{{overarc|83}}</nowiki>}}
* {{demo-inline|<nowiki>0.{{overarc|142857}}</nowiki>}}
* {{demo-inline|<nowiki>0.{{overarc|012345679}}</nowiki>}}
* {{demo-inline|<nowiki>3.{{overarc|142857}}</nowiki>}}
* {{demo-inline|<nowiki>{{overarc|''AB''}}</nowiki>}}

== Technical details ==
{{Tracked|T32215}}

This template is a workaround for the [[mw:Extension:Math|Math]] extension's [[Help:Displaying a formula#Arc notation \overarc|lack of support]] for the <code>\overarc{…}</code> function in [[LaTeX]]:

<syntaxhighlight lang="latex">
0.\overarc{012345679}
</syntaxhighlight>

<math>0.\overarc{012345679}</math>

== Accessibility ==
This template is purely presentational, relying on the [[CSS]] property [[devmo:Web/CSS/border-radius|<code>border-radius</code>]] and browser support for elliptical borders. To ensure that screen readers produce meaningful results, consider prepending something like {{tlx|Screen reader-only|repeating&nbsp;}} for a repeating decimal or {{tlx|Screen reader-only|arc&nbsp;}} for a reference to a geometric arc.
