Trying to set value in array to a constant

I'm having trouble setting the value of "price" to 999, but it keeps pulling the value of 800 from the database:

<?php
namespace Hera;

require_once ("dbcontroller.php");
$db_handle = new DBController();

$productByCode = $db_handle->runQuery("SELECT * FROM tblproduct WHERE code='LPN45'");

$itemArray = array(
   $productByCode[0]["code"] => array(
   'id' => $productByCode[0]["id"],
   'name' => $productByCode[0]["name"],
   'code' => $productByCode[0]["code"],
   'quantity' =>2,
   'price' => "999",
   'image' => $productByCode[0]["image"]
   )
);               
echo print_r($productByCode[0]["price"]);
echo "<br>";
echo $productByCode[0]["price"];
echo "<br>";
print_r($productByCode[0]["price"]);
echo "<br>";
echo round($productByCode[0]["price"], 2);
echo "<br>";
?>

Select allOpen in new window

It, doesn't pull the 999, it results in:

800.001

800.00
800.00
800
