that the number is not rounded but truncated to 0, as the int documentation will tell you.

You can get around the truncation problem fairly easily with:

$string = int( ($number * 100) + 5 ) / 100;
Update: Well Alright then for the pedantic among us, see below ;-) (no offence meant, please don't take any)
my $dec = 100; # Change as appropriate to give you the number # of decimal places you want int( ($number * $dec) + int($number * $dec) % 2 ? 0.5 * $dec : 0) / $dec
That should sort out the rounding towards an even number.
