Template documentation[view] [edit] [history] [purge]

This template may be used to enclose text between two vertical bars (Template:Unichar), 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 |x| < 7, the function is positive.

The notation {{math|{{abs}}}} means ''absolute value''.

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

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