Description:
------------
When you select and fetch integers and reals from an SQLite database, they are returned as strings.  Why?  I would prefer that when I fetch an integer (or a float), the SQLite PDO driver give me an integer (or a float) rather than converting everything to a string (which is annoying).  Thanks!

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

$pdo = new PDO ('sqlite::memory:');
// $select = $pdo->query ('select 5 as foo, typeof (5) as bar;');
$select = $pdo->query ('select 5.0 as foo, typeof (5.0) as bar;');
$row = $select->fetch (PDO::FETCH_ASSOC);

print "actual result:\n";
var_dump ($row);

print "\n";

print "expected result:\n";
$row['foo'] = (float) 5.0;
var_dump ($row);

?>


Expected result:
----------------
array(2) {
  ["foo"]=>
  float(5)
  ["bar"]=>
  string(4) "real"
}


Actual result:
--------------
array(2) {
  ["foo"]=>
  string(3) "5.0"
  ["bar"]=>
  string(4) "real"
}
