Template documentationThis template may be used to enclose text between two pairs of vertical bars (U+007C | VERTICAL LINE), such as to denote the norm. It adds padding (of width 0.1 em) on each side inside the bars.
Usage
When {{math|{{norm|''x''}} < 7}}, the function is positive.
When ||x|| < 7, the function is positive.
The notation {{math|{{norm}}}} means ''norm''.
The notation || · || means norm.
Alternatives
This template is equivalent to enclosing the text between two pairs of {{pipe}} templates (plus padding of width similar to hair spaces around the argument)
When {{math|{{pipe}}{{pipe}} <!-- hair space -->''x'' {{pipe}}{{pipe}} < 7}}, the function is positive.
When || x || < 7, the function is positive.
