Hi,
I have two separate issues here. First, I'm struggling to get math cases
to work. The wiki suggests that the following code
\starttext
\startformula
f(x) = \startmathcases
\NC x, \NC if $0 \le x \le \frac12$ \NR
\NC 1-x ,\NC if $\frac12 \le x \le 1$ \NR
\stopmathcases
\stopformula
\stoptext
should typeset everything after the \NC in text mode, but when I compile
it's still in math mode. Is this a bug or is the wiki out of date?
Secondly, how can I enter text mode whilst in a formula, whilst also
only using the roman font? For example, I would like it so that even if
the whole text is wrapped in {\em ...}, the text in the formulae are in
roman font. I've tried the following:
\starttext
{\em
\startformula \startalign[align=left]
\NC {\rm multiple words of text} \NR % Does not provide spacing
\NC \mathrm{multiple words of text} \NR % Does not provide spacing
\NC \text{multiple words of text} \NR % Still italicised
% \NC \text{\rm multiple words of text} \NR % Error
% \NC {\rm \text{multiple words of text}} \NR % Error
\stopalign \stopformula
}
\stoptext
Thanks,
Jack
