Summary: 0003469: quercus float/rounding bug
Description: I have a report that accumulates odometer values it pulls from the db. You can see in the image it does some funky math while interpreting this code:

    while($rs->moveNext())
    {
      $vehId = $rs->fields['veh_id'];
      
      if ($showSummary)
      {
        if (!isset($odomCache[$vehId]))
          $odomCache[$vehId] = 0;
        $odomCache[$vehId] += $rs->fields['distance_from_last'];
        $rs->fields['odom'] = $odomCache[$vehId];
      }
    }

I've put the list of values below.

note the two image files are mis-named -rounding. In reality, there should not need to be any rounding.

Can you try the Resin 4.0 snapshot at: http://www.caucho.com/download [^]

We had made our float rounding to be more like PHP.

I tried resin 4, but I cant even log into the app b/c it wont connect to db. See bug: http://bugs.caucho.com/view.php?id=3471 [^]
