@minus
(−): Inserting a Minus Sign ¶Use the @minus{}
command to generate a minus sign.
Where the character encoding and font used in the output allow it,
the symbol is the customary length for a minus sign—a little longer
than a hyphen, shorter than an em-dash:
‘−’ is a minus sign generated with ‘@minus{}’, ‘-’ is a hyphen generated with the character ‘-’, ‘—’ is an em-dash for text.
If you actually want to typeset some math that does a subtraction, it
is better to use @math
, as in @math{a-b}
(see @math
and @displaymath
: Formatting Mathematics).
