Roman numerals

[jamesons...@gmail.com]

Someone on my site is trying to use the following command:

\MakeUppercase{\text{\romannumeral 1}}

Both parts aren't rendering but he claims this renders properly on his Latex program. In the future, should I look at a list of your extensions before asking about this? I'm not able to find it right now but I don't want to waste your time. Any comments though on the above command are appreciated.

From the documentation:

Note that the TeX input processor implements only the math-mode macros of TeX and LaTeX, not the text-mode macros. MathJax expects that you will use standard HTML tags to handle formatting the text of your page; it only handles the mathematics. So, for example, MathJax does not implement \emph or \begin{enumerate}...\end{enumerate} or other text-mode macros or environments. You must use HTML to handle such formatting tasks. If you need a LaTeX-to-HTML converter, you should consider other options.

see

http://docs.mathjax.org/en/latest/tex.html

for the details of the TeX support in MathJax. MathJax is extendible and if some missing commands turn out to be really needed, then you can implement a extensions to implement them. It seems to me that a first approximation would be to just use a capital I here.
