<?php
$test="2.03";
$amount=($test*100);
echo $amount . "\n";
printf("%06d\n",$amount);
$amount=(2.03*100);
printf("%06d\n",$amount);
?>


Produces the following output:

203
000202
000202

My math is a little fuzzy but I think 2.03 * 100 = 203. This
used to work in php 3.x but seems to be broken since the 4.x
beta.

The famous rounding issue.
By using 'f' (float) would give you correct result.
Not a bug.
