php not multiply

[Salvis]

I have code:

   <?php
$_GET["price"]="3.13";
$_GET["currency"]="EUR";
         if($_GET['currency']!="LVL"){
            $bank=simplexml_load_file('http://valutas.info/xml/'.$_GET["currency"]);
                foreach ($bank->item->rates as $item)
                        echo "Kurss: ".$item->sellInCash."<br />";
                        echo "Cena: ".$_GET['price']."<br />";
                        $kaka=$_GET['price']*$item->sellInCash;
                        echo "Reizinasana: ".$kaka."<br />";
                        $tests1="0.7028000000000";
                        echo "Tests: ".$_GET["price"]*$tests1."<br />";

                    }            
            }
?>

I noticed that

$_GET['price']*$item->sellInCash

gives out 0

but

$_GET["price"]*$tests1

returns all correct.

Why? Where is mistake?

I'd be inclined to believe that $item->sellInCash contains an incorrect value, or rather something that is 0 when cast to int.

And to check what's in there:

var_dump($item->sellInCash);

[Salvis]

var_dump($item->sellInCash);

returns:

object(SimpleXMLElement)#5 (1) { [0]=> string(5) "0.708" } 

[Mchl]

How about

var_dump($item->sellInCash[0]);

[Salvis]

If i use

$kaka=$_GET['price']*(double)$item->sellInCash;

on line #9, it works!

 

Thanks all for helping.
