14.7.9 @minus
(-): Inserting a Minus Sign
Use the @minus{}
command to generate a minus sign. In a
fixed-width font, this is a single hyphen, but in a proportional font,
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.
In the fixed-width font used by Info, @minus{}
is the same
as a hyphen.
You should not use @minus{}
inside @code
or
@example
because the width distinction is not made in the
fixed-width font they use.
When you use @minus
to specify the mark beginning each entry
in an itemized list, you do not need to type the braces
(see section @itemize
: Making an Itemized List).
If you actually want to typeset some math that does a subtraction, it
is better to use @math
. Then the regular ‘-’ character
produces a minus sign, as in @math{a-b}
(see section @math
: Inserting Mathematical Expressions).
