How to round to two decimal places?

Question

PHP

require_once 'phpquery.php';
  function get_price($url) {
    $html = file_get_contents($url);
    $doc = phpQuery::newDocument($html);
    $price = $doc->find('/* Иду до числа типа float, вот до такого 74,5995*/')->text();

    return (float) (round($price, 2));
  }
        echo get_price(/* Туть юрл */);

The returned number is a floating point number, and when it is returned I round it to 2 decimal places, but it is output as an integer.
