in reply to perl newbie question

Sure ... but why wouldn't you want to use s/printf?

At the risk of answering a homework question: 

$newtemp =int(100*((($temp-32)*5)/9))/100;

    Note that int always rounds towards zero. To get it to round (more) correctly: 
    $newtemp =100*((($temp-32)*5)/9);
if ($newtemp > 0) {
  $newtemp = int($newtemp + 0.5)/100;
} else {
  $newtemp = int($newtemp - 0.5)/100;
}

    But (s)printf really is the right solution here...
