This is my private mail address. Post to the list by mailing to the address [EMAIL PROTECTED] I have forwarded this mail there. >From your subject line it sounds like you know the answer already. If you multiply the value up so that all the digits you want are to the left of the decimal point then you can use 'int' before scaling it back. my $val = 24.325613832; print int ($val * 100) / 100; OUTPUT 24.32 You question says the result should be 24.33, which is wrong - this would involve rounding as well. If that's what you want, then think how you could transform all values from 24.325 to 24.335 to something between 2433.0 and 2433.99. Then you can use 'int' like I did above and reverse the scaling.
