<?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?
