Mark-
I've tried that. The function &roundto($x,$n) works fine in problem scripts,
but returns "undefined" in the spreadsheet.

Rex,
There is a function: roundto(x,n) available in perl safe space within the
coding of a
problem. You might try it to see if it works in the spreadsheet.
$y = &roundto($z,3);
will round z to 3 decimal places.
Later,
Mark
