Element formatting

assuming we have:

    <div class="prices">
        <span class="price">12434.445</span>
        <span class="price">123434545</span>
        <span class="price">12345.7834893748973</span>
        <span class="price">15.56</span>
    </div>

the script:

    $('.price').number_format(2, '.', ',');

will convert it to:

    <div class="prices">
      <span class="price">12,434.45</span>
      <span class="price">123,434,545</span>
      <span class="price">12,345.78</span>
      <span class="price">15.56</span>
    </div>
