Template:Norm

Template documentation

This 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}}&#x200A;<!-- hair space -->''x''&#x200A;{{pipe}}{{pipe}} < 7}}, the function is positive.

When || x || < 7, the function is positive.
