Description:
------------
Money column is wrongly converting to the char column and this cause that value is rounding to the 2 digits after delimiter (dot).

Test script:
---------------
$dsn = 'mssql:dbname=DBNAME;host=HOSTNAME';
$user = 'USERNAME';
$password='PASSWORD';
$dbh = new PDO($dsn, $user, $password);
$sth = $dbh->query  ('create table #tmp(col money)');
$sth = $dbh->query  ('insert into #tmp(col) values(-0.1234)');
$sth = $dbh->query  ('insert into #tmp(col) values(0.1234)');
$sth = $dbh->prepare('select * from #tmp');
$sth->execute();
$r = $sth->fetchAll(2);
print_r($r);

Expected result:
----------------
Array
(
    [0] => Array
        (
            [col] => -0.1234
        )

    [1] => Array
        (
            [col] => 0.1234
        )

)

Actual result:
--------------
Array
(
    [0] => Array
        (
            [col] => -0.12
        )

    [1] => Array
        (
            [col] => 0.12
        )

)
