show percentage discount price

[markauberg]

Hi, I need to see a percentage discount on the product page, but it counts me wrong.
Where am I making a mistake ?
Thank you

{if $product.discount_type === 'percentage'} <span class="badge badge-discount discount discount-percentage">-{$product.discount_percentage_absolute}</span> {else} <span style="color:#000; font-weight:600;font-size: 1.2em;"><!--{$product.discount_to_display}--> -{round(($product.price / $product.regular_price) * 100,2)} %</span> {/if}
