This template may be used to enclose text between two [[vertical bar]]s ({{unichar|007C|vertical line}}), such as to denote the [[absolute value]].  It adds padding (of width 0.1 em) on each side inside the bars. 

== Usage ==

<pre>
When {{math|{{abs|''x''}} < 7}}, the function is positive.
</pre>
When {{math|{{abs|''x''}} < 7}}, the function is positive.

<pre>
The notation {{math|{{abs}}}} means ''absolute value''.
</pre>
The notation {{math|{{abs}}}} means ''absolute value''.

== Alternatives ==

This template is equivalent to enclosing the text between two {{tlx|pipe}} templates (plus padding of width similar to [[hair space]]s around the argument)
<syntaxhighlight lang="html">
When {{math|{{pipe}}&#x200A;<!-- hair space -->''x''&#x200A;{{pipe}} < 7}}, the function is positive.
</syntaxhighlight>
When {{math|{{pipe}}&#x200A;<!-- hair space -->''x''&#x200A;{{pipe}} < 7}}, the function is positive.
