Nathan,
A workaround would be to do a sprintf in the script and then use the string in
the text of the problem.
<script type=“loncapa/perl”>
$length = 157;
$result = sprintf("%.02E", $length);
</script>
<startouttext/> The length is $result meters.<endouttext/>
It’s a bit cumbersome, but it looks like it works.
