The test-case hasn't been corrected for PHP 4.3.3-dev
------------------------------------------------------------------------

Should always test myself and not trust others:
# /usr/src/web/php/php5/sapi/cli/php -n t.php
5.04499999999999992894573
5.04999999999999982236432
5.04999999999999982236432
5.05
No bug anywhere.

With this script:
<?php
$mul = 1;
$one = 5;
$two = 0.9;
ini_set("precision", 24);
$res = 5 * (1 + (0.9 / 100));
$bar = round($res, 2);
$foo = round(1 * $bar, 2);
echo $res, "\n", $bar, "\n", $foo, "\n";
echo sprintf("%1.2f", $foo);
?>
Result with PHP 4.3.3-dev:
5.04499999999999992894573
5.04999999999999982236432
5.04999999999999982236432
5.05
Result with PHP 4.2.3:
5.04499999999999992894573
5.04000000000000003552714
5.04000000000000003552714
5.04
Nokia 6120 (the $res):
5.045
TI-32:
5.045
With pen and paper:
5.045
Round 5.045 with precision of 2 == 5.05
So I think PHP 4.3.2 actually works as expected
and anything before (and after, PHP 5? :) doesn't.
Reclassified as ZE2 bug.

hmm, actually this changed between PHP 4.2.2, PHP 4.2.3 an PHP 4.3.0:
[EMAIL PROTECTED] derick]$ cat foo.php
<?php
$mul = 1;
$one = 5;
$two = 0.9;
echo sprintf("%1.2f", round($mul * round($one * (1 + ($two / 100)), 2),
2));
?>
[EMAIL PROTECTED] derick]$ php-4.2.2 foo.php
5.04
[EMAIL PROTECTED] derick]$ php-4.2.3 foo.php
5.05zend_hash.c(98) : Bailed out without a bailout address!
[EMAIL PROTECTED] derick]$ php-4.3.0 foo.php
5.05
[EMAIL PROTECTED] derick]$ php-4.3.0dev foo.php
5.05
[EMAIL PROTECTED] derick]$ php-5.0.0dev foo.php
5.04
So something is definitely screwed in the PHP_4_3 branch
