How to show product_id in Front office

[zahiras]

Hi everyone!
Right now Prestashop shows product reference on the product front page:
 

 <div class="feature_line" id="product_reference" {if isset($groups) OR !$product->reference}style="display: none;overflow: hidden;"{else}style="overflow: hidden;"{/if}><span class="feature_line_left">{l s='Product code'}:</span><span class="feature_line_right" itemprop="sku">{$product->reference|escape:'htmlall':'UTF-8'}</span></div>

How can I change it, in order to show product id (numbers)? I tried for 2 hours with no success :/ 
I'm editing product_tpl file.

Hi,

Please try with: {$product->id|intval}

Thanks,

Hello prestamonste!
Your answer was not completely accurate, but gave a hint. Thank you
There were needed more changes in the code. This code shows product ID instead of reference number:
 

<div class="feature_line" id="product" {$product->id|intval}><span class="feature_line_left">{l s='Product code'}:</span><span class="feature_line_right" itemprop="sku">{$product->id|intval}</span></div>
