Actually if you do that, then you it will not round properly. e.g. it fails in the following examples:

$distance=1.0050000     returns $roundeddistance = 1 (should be 1.01)
$distance=1.9000000     returns $roundeddistance = 1.9 (should be 1.90)


You should use sprintf function to round decimals:

$roundeddistance = sprintf "%0.2f", $distance;

Or, if you want it to to look a bit cleaner (i.e. have a leading '0' - 0.21 instead of .21) then you can use the following:

$roundeddistance = sprintf "%1.2f", $distance;

Hope this helps.
