Query execution behaves differently when I use Input core library

Hello guys! I am new to CodeIgniter and I have started implemention with it! I like it.

 I am facing a strange problem here and I will need you help. I will attach my code and logs:

Example correct:

PHP Code:

    public function searchTest() {
        $myparams = array();
        $myparams[] = 200;

        $sql = "
            SELECT
                    id,
                    title
            FROM
                    movies
            WHERE length > ?
        ";

        $q = $this->db->query($sql, $myparams);
        log_message('debug', 'myparams: '.print_r($myparams, true));
        log_message('debug', 'Rows: '.count($q->result_array()));
    } 


Logs of correct example:

Now here is the Strange/Incorrect example:

PHP Code:

    public function searchTest() {
        $myparams = array();
        $myparams[] = $this->input->get('length');

        $sql = "
            SELECT
                    id,
                    title
            FROM
                    movies
            WHERE length > ?
        ";

        $q = $this->db->query($sql, $myparams);
        log_message('debug', 'myparams: '.print_r($myparams, true));
        log_message('debug', 'Rows: '.count($q->result_array()));
    } 


Here are the logs of the incorrect example:

05/10 02:39:18.588 - INFO  --> Config Class Initialized
05/10 02:39:18.588 - INFO  --> Hooks Class Initialized

The only difference in these two examples is this:

$myparams[] = 200;

$myparams[] = $this->input->get('length');

The first example returns only 1 row in the query result, while the second example returns an incorrect number of rows.

What is happening here ?

(If you have time, please have a local test and provide feedback)

OK guys, the solution is this:

$myparams[] = (int) $this->input->get('length');

Previously the CI treated $this->input->get('length') as a string.
