I have a question about rounding values to, say, 3 or 4 digits in the spreadsheet.  I've come up with the following hack that does the job, but i was wondering if there was a more elegant (built-in?) way to do it.


$x = &SUMSEQ("T","regexp:Homework")/&SUMSEQ("S","regexp:Homework")*100;
$x *= 1000;
$x = int($x);
$x /= 1000;
$x; 

In the above code, columns S and T contain points available and points earned, depending on whether the due date has passed or not.
