<?
$int = 0.293847289472983;
echo $int ."\n";
echo round($int,2) . "\n";
echo round((int)$int,2) . "\n";
echo round((float)$int,2) . "\n";
echo round((double)$int,2) . "\n";
?>
outputs on php 4.0.6:
0.29384728947298
0.29
0
0.29
0.29
however, using php 4.1.0, it outputs:
0.29384728947298299761570206101168878376483917236328125

is this a bug, or a new 'feature' ? Closest report I found was http://marc.theaimsgroup.com/?l=php-dev&m=100750316722784&w=2
on the php-dev mailinglist.
