Template:Prod
[⧼Purge⧽ Template:Prod]
though with some compromises to obtain [more or less] acceptable results with MS Internet Explorer (or now MS Edge) and Google Chrome.
The {{prod}} (product operator) mathematical formatting template is used to obtain an HTML+CSS or a LaTeX formatted product expression.
Contents
Usage
- {{prod|from|to}} (followed by multiplicand, as with LaTeX; format defaults to
htm
)
or
- {{prod|from|to|format}} (followed by multiplicand, as with LaTeX)
or
- {{prod|from|to|multiplicand}}
or
- {{prod|from|to|multiplicand|format}}
where format is one of the following:
-
htm
: HTML+CSS markup (text style, with postscript limits) for product expression (default); -
HTM
: HTML+CSS markup (display style, with underscript/overscript limits) for product expression; -
tex
: LaTeX markup (text style, with postscript limits) for product expression; -
TEX
: LaTeX markup (display style, with underscript/overscript limits) for product expression.
