<?php

$x = 10.95;
$y = 0.70;

$e = $x*$y;

print "Discounted price = $e\n";

var_dump($e);

$z = round($e, 2);

var_dump($z);

print "Rounded Price = $z\n";

// this works grrr

$x = round(7.665, 2);

print "Working example of round = $x\n";

?>

Produces

[cnewbill@storm cnewbill]$ php -q t.php
Discounted price = 7.665
float(7.665)
float(7.66)
Rounded Price = 7.66
Working example of round = 7.67
[cnewbill@storm cnewbill]$ php -v
4.0.6

Which is wrong, it should be 7.67.  If I don't do the multiplication and
simply send round 7.665 it works right!!??

Any ideas?
