Question

I have a problem with LaTeX – I don’t know how to put mathematical equations and symbols in listings. I use the listings package and it’s offers great looking listings, but it doesn’t allow math symbols in $ ... $. Another package, algorithms, allows math, but listings doesn’t look as good as with listings (the problem is that algorithms demands to get new line after every if, then, etc.)

Answer 1

You can use the option mathescape for your environment which gives you the ability to use the normal latex behavior of the $-signs. Try:

\begin{lstlisting}[mathescape]
...
\end{lstlisting}

For more info, take a look into the listings package manual.
