Template:Mathbb/doc
The {{mathbb}} mathematical alphanumeric symbols template is intended to simulate a Blackboard Bold (Open Face, Double Struck)[1] font for use in mathematical formulas using standard HTML+CSS. The template does not attempt to use any Blackboard Bold font that may be installed on several operating systems, either as default or as part of a package. (Currently, since we can't rely on those fonts being installed, the template resorts to using Unicode code points.) This template may also be used to get \mathbb{...}
in LaTeX markup (see Help:Displaying a formula).
Contents
Usage
- {{mathbb|text}}
or
- {{mathbb|text|format}}
where text is
- a Latin alphabetic character (uppercase or lowercase) or a Hindu-arabic numeral (LaTeX only supports uppercase Latin characters);
and format is among
- htm: to get HTML+CSS (default),
- tex: to get LaTeX code.
Tests
The code
- {{mathbb|ABCDEFGHIJKLMNOPQRSTUVWXYZ abcdefghijklmnopqrstuvwxyz 0123456789}}
yields
- Mathbb error: Only a single Latin alphabetic character (uppercase or lowercase) or a Hindu-arabic numeral is currently supported with the HTML+CSS option.
