Description:
------------
When I select a float column in an SQL query, the value returned has the decimal point moved one place to the right.
123.5000 would be returned as 1235.000. This seems to happen for any value that has a non-zero digit to the right of the decimal point, so 123.000 would be returned properly.

Reproduce code:
---------------
$sql = "select my_float_col from my_test_table";
$res = $ifxpdo->query($sql);
$row = $res->fetch(PDO::FETCH_OBJ);
print_r($row);


Expected result:
----------------
With a test value of 123.500, I expect to see the result of 123.500.

Actual result:
--------------
The actual result would be 1235.00.
