Don't know if this'll work or not, but try dividing by a hundred (or 10 or 1000):

PHP Code:

if($stats['activepercent'] > 100)
{
$statscache['activepercent'] = vb_number_format(($numbermembers / $newuserid) * 100 / 1000, 2 ) . '%'; 
}
else
{
 $statscache['activepercent'] = vb_number_format(($numbermembers / $newuserid) * 100, 2) . '%';
}
