in reply to Strange int() result

The simplest way to round to a whole number is to add 0.5 before truncating with int:

19:26 >perl -wE "say int(35784.45 * 100); say int(35784.45 * 100 + 0.5 +);" 3578444 3578445 19:27 >

Hope that helps,

    ... and for negative values subtract 0.5
    perl -wE "say int(-35784.45 * 100 - 0.5);" -3578445
