The conditional statement is illustrated in Figure~\ref{fig:conditional}.

\begin{figure}
\tt \small
\begin{verbatim}
if
    (x>0)
then
    return x
else
    return -x;
\end{verbatim}
\caption{Example of a conditional statement.}
\label{fig:conditional}
\end{figure}

\LaTeX\ will move the figure to a point not earlier than the page on
which the text preceeding the figure lies.  Note that a backslash is
required after the macro call to \verb+\LaTeX+ in the preceeding
sentence.
