Graphics, Figures & Tables ⇒ how to assign a value to a variable

[steem84]

Hello,

I am a newbe in Latex and I'm wondering how to assign a value to a variable. This could then be useful to give every figure a constant figure width, for example. This is what I am trying to do


\newcommand{\figurewidth}{0.9\textwidth}

% and then later, in the figure enviroment

\begin{figure}
\includegraphics[width=\figurewidth]{dog}
\end{figure}


unfortunately integers do not work with \newcommand. How to do this?

Just use \newlength{\figurewidth} and then \setlength{\figurewidth}{0.9\textwidth}.

See LaTeX lengths.

That does the job. Thanks!
