Description:
------------
PHP:  PHP 5.3.10-1ubuntu3.11 with Suhosin-Patch and PHP 5.5.9-1ubuntu4 (my test env).  Appears to span multiple versions.

Description:  Using SimpleXML Nodes in mathematical equations doesn't correctly convert strings to floats, as expected, but only to integers (stopping at the decimal).

Modules:  aptitude managed, with cURL installed.  Everything else is vanilla.



FYI - the "PHP Version" can't be changed on the bug submitting form after an error occurs when submitting asking me to change it....

Test script:
---------------
<?php

// Does NOT work as expected.
$sxml = simplexml_load_string('<test><num>20.5</num><den>1</den></test>');
$ans = $sxml->num / $sxml->den;

echo "XML Test:\n";
echo "{$sxml->num} / {$sxml->den} = {$ans}\n";
// Output:  20.5 / 1 = 20



// Works as expected.
$num = "20.5";
$den = "1";
$ans = $num / $den;

echo "String Test:\n";
echo "{$num} / {$den} = {$ans}\n";
// Output:  20.5 / 1 = 20.5
