Maybe some fellow monk can fill me in on how to use the int-function, with which perl cuts the decimals of a floating point number. Let me phrase my specific question as a debugger meditation: (perl -d -e 1, which explains, why there are no ";" between the commands) 

$i = 1.255
$j = $i * 100 + 0.5
$j = $j * 10000000
<p>
print $j
<p>
  ->  1260000000
<p>
print int ( $j )
<p>
  ->  1259999999

Is there a way to make perl behave as a humble user of arithmetics would have expected, without needing additional modules like Math::Round?
