Object of class stdClass could not be converted to int
<p>I have error like this
Object of class stdClass could not be converted to int</p>

<p>controller</p>

<pre><code>if ($this-&gt;input-&gt;post('nama') == 'pendek boju jeans') {
                    $a=0.810;
                }else{
                    $a=1.144;
                }
                $kain= $this-&gt;input-&gt;post('id_kain');
                $b=$this-&gt;jeans_model-&gt;luaskain($kain);
                $tpotongan=round($a/$b);
</code></pre>

<p>model</p>

<pre><code>    public function luaskain($kain)
  {
    $this-&gt;db-&gt;select("ukuran");
    $this-&gt;db-&gt;from("bahankain");
    $this-&gt;db-&gt;where('id_kain',$kain);
    $query = $this-&gt;db-&gt;get();
    return $query-&gt;row();
  }
</code></pre>

<pre><code>|ukuran|
|800|
</code></pre>
