Description:
------------
This is similar to the bug 67839.

The patch for that was only done to the mysqlnd driver and needs to be reapplied to the libmysqlclient driver as well.

Test script:
---------------
On a MySQL DB, run the following queries:

CREATE TABLE test(id INT PRIMARY KEY, fp4 FLOAT, fp8 DOUBLE) ENGINE = InnoDB;
INSERT INTO test(id, fp4, fp8) VALUES (1, 9.9999, 9.9999)

Now using mysqli, SELECT the one row out:
        $id = null;
        $fp4 = null;
        $fp8 = null;

        $stmt = mysqli_prepare($link, "SELECT * FROM test");
        mysqli_stmt_bind_result($stmt, $id, $fp4, $fp8);
        mysqli_stmt_execute($stmt);
        mysqli_stmt_fetch($stmt);

        $test = array($id, $fp4, $fp8);

        var_dump($test);


Expected result:
----------------
It should be:
array(3) {
  [0]=>
  int(1)
  [1]=>
  float(9.9999)
  [2]=>
  float(9.9999)
}

Actual result:
--------------
The output will be:
array(3) {
  [0]=>
  int(1)
  [1]=>
  float(9.9998998642)
  [2]=>
  float(9.9999)
}
