Template documentationThis template may be used to enclose text between two vertical bars (U+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
When {{math|{{abs|''x''}} < 7}}, the function is positive.When <span class="texhtml " {{#if:|x| < 7, the function is positive.
The notation {{math|{{abs}}}} means ''absolute value''.The notation <span class="texhtml " {{#if:| · | means absolute value.
Alternatives
This template is equivalent to enclosing the text between two {{pipe}} templates (plus padding of width similar to hair spaces around the argument)
When {{math|{{pipe}} <!-- hair space -->''x'' {{pipe}} < 7}}, the function is positive.When <span class="texhtml " {{#if:| x | < 7, the function is positive.
