Thank you!
In the manual only casting to (string) is mentioned. If casting to
float is necessary too, I think it should be mentioned in the manual,
because it is not "usual php behaviour".
btw. I don't understand why casting must be necessary here, because it
is not necessary when using arrays or anything else. I think it's
confusing for many people.

Works with latest CVS. (you need to cast the stuff to float / string
though)

Description:
------------
If I want to calculate with numbers (decimals) from an xml file/string
parsed by simplexml, php does not convert these strings (e.g. "1.2") to
float (1.2), it converts them to integer (1).
Reproduce code:
---------------
<?php
$xmlstr = <<<XML
<?xml version='1.0' standalone='yes'?>
<test>
<num>1.2</num>
<num>0.2</num>
<num>0.5</num>
</test>
XML;
$xml = simplexml_load_string($xmlstr);
foreach ($xml->num as $number) {
echo $number, " * 3 = ", $number * 3, "\n";
echo "var_dump: ", var_dump($number), "\n";
}
$number_array = array('1.2', '0.2', '0.5');
foreach ($number_array as $number) {
echo $number, " * 3 = ", $number * 3, "\n";
echo "var_dump: ", var_dump($number), "\n";
}
?>
Expected result:
----------------
The following loop:
foreach ($xml->num as $number) {
echo $number, " * 3 = ", $number * 3, "\n";
}
should display:
1.2 * 3 = 3.6
0.2 * 3 = 0.6
0.5 * 3 = 1.5
(as it actually works with $number_array)
Actual result:
--------------
1.2 * 3 = 3
0.2 * 3 = 0
0.5 * 3 = 0
