Hi,
I could have used array instead of longtable but, it is not handy to
write "normal text" within the mathematical mode and I need to mix both...
the package "array" helps. it defines the >{} and <{} column modifiers
for tabular environments:
\documentclass{minimal}
\usepackage{fontspec}
\usepackage{unicode-math}
\setmainfont{Linux Libertine O}
\setmathfont{Asana Math}
\usepackage{array}
\begin{document}
\begin{tabular}{l>{$}l<{$}}
5+7&5+7
\end{tabular}
\end{document}
The second column is in math mode.
Ross has pointed the problem of spacing and shape of mathematical symbol
(and some oher ones..): indeed \texttimes is not the same as $\times$
for instance.
And that should be thought about. What do you want to express: Some kind
of math, then it should be typed like math. A symbol for the grammatical
numerals "five" and "seven"? Then it should be typed like text.
Btw: It's spacing and font which differ in math- and text-mode.
Btw2: The multiplication sign is in unicode at u00d7: ×.
I was wondering if there would be some fonts feature like:
[Numbers=OldStyle], one could imagine: [Numbers=MathNumbers]
You have a lot of similar options if you use kpfonts. Unfortunately,
these kpfonts do not work with xelatex and I need xelatex, to have
Sanskrit texts (which I mix in my article) hyphenated... I don't know
how to adapt the gloss-sanskrit.ldf file for a use with babel.
Thanks for all these answers.
Another solution: the package "siunitx" supplies a good number parser.
Try the following:
\documentclass{minimal}
\usepackage{fontspec}
\usepackage{unicode-math}
\setmainfont{Linux Libertine O}
% \setmainfont{TeX Gyre Pagella}
\setmathfont{Asana Math}
\usepackage{siunitx}
\begin{document}
5×7 : \(5\times 7\) : \num{5x7} : \sisetup{mode=text}\num{5x7}\\
\end{document}
Yet another solution: The font TeX Gyre Pagella is similar to Linux
Libertine and works like charm with the math font Asana Math. Simply
change the comments before the \setmainfont-commands in the above examples.
Bye
Toscho
