[pdftex] calculating in LaTeX

[David Carlisle]

this is a latex question not a pdftex one, so it's teh wrong list but
anyway

I think it would be if you loaded calc package, otherwise declare a new
length, \mylength in the document preamble then you could go


\newcommand{\mycommand}[2]{\begin{figure}
\setlength{\mylength}{#1} \includegraphics[height=\mylength,
width=2\mylength]{#1} \end{figure}}

> Is there any way to evaluate expressions?
see the calc package.
