Bug description: PDO Mysql returns garbage value for float column
Description:
------------
When selecting from a FLOAT column, PDO returns garbage instead of the
right value.
Tested in PHP 5.1.2 and 5.1.6; both fail in similar ways.
Reproduce code:
---------------
<?php
error_reporting(E_ALL);
$db = new PDO("mysql:host=localhost;dbname=test", 'root', '', array());
$db->setAttribute(PDO::ATTR_ERRMODE,PDO::ERRMODE_EXCEPTION);
$db->exec("CREATE TEMPORARY TABLE test ( num FLOAT NOT NULL)");
$db->exec("INSERT INTO test VALUES (1.5)");
$st = $db->query("SELECT * FROM test");
$row = $st->fetch(PDO::FETCH_ASSOC);
var_dump($row);
?>
Expected result:
----------------
array(1) {
["num"]=>
string(12) "1.5"
}
Actual result:
--------------
array(1) {
["num"]=>
string(12) "-2.87989e-05"
}
Also other incorrect values; it seems nondeterministic.
