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

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

<pre>
The notation {{math|{{norm}}}} means ''norm''.
</pre>
The notation {{math|{{norm}}}} means ''norm''.

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

* {{tl|abs}}
* {{tl|bra-ket}}
* {{tl|langle}} and {{tl|rangle}}
