Description:
------------
I'm working with geolocation and storing latitude and longitude data in a DOUBLE PRECISION field on firebird.

When searching for these records, the PDO is rounding the values, as well as returning them as a string.

The insertion of the data is not done from PDO but by an external system and is correct.

Test script:
---------------
<?php
  $conn = new PDO("firebird:dbname={$database}", "SYSDBA", "masterkey");

  $query = $conn->query('SELECT CAST(25.3639309364232 AS DOUBLE PRECISION) FROM RDB$DATABASE');

  echo $query->fetchColumn();

Expected result:
----------------
25.3639309364232

Actual result:
--------------
25.363931
