Template:Overarc

New page

<noinclude>{{Documentation subpage}}</noinclude>

{{high-use| 1377 }}
Produces an overline. <code><nowiki>{{overline|RESET}}</nowiki></code> gives {{overline|RESET}}. For a single letter, the Unicode combining accent U+0305 is a possible alternative: <code>x&#x0305;</code> or <code>x&#773;</code> produces x̅. For multiple letters, use the Unicode method when it is not desired for the overline to be continuous: <code><nowiki>{{overline|x}}{{overline|x}}{{overline|T}}{{overline|T}}</nowiki></code> gives {{overline|x}}{{overline|x}}{{overline|T}}{{overline|T}}; <code>x&#x305;x&#773;T&#773;T&#773;</code> gives x̅x̅T̅T̅. The wikitext may be rendered easier to read by using the Unicode method, previewing the page, and copying and pasting the overlined text into the wikitext.

==Parameters==
There is a mandatory first parameter, followed by an optional second parameter. If the second parameter is used, only the second parameter will be under the overline.

*{{tlc|overline|EXIT}} → {{overline|EXIT}}
*{{tlc|overline|12.|3}} → {{overline|12.|3}}

The second produces exactly the same formatted output as <code><nowiki>12.{{overline|3}}</nowiki></code>, but may be preferred when formatting [[repeating decimal]] numbers as it is easier to see the number in the wikitext.
