function updateTotalBasket(){
    var basketItems = document.querySelectorAll(".basket_item");
    var quantity;
    var price;
    var totalPrice = 0.00;
    basketItems.forEach((item) => { 
        quantity = item.querySelector(".quantity");
        price = item.querySelector(".price");
        console.log("quant : " + quantity.value);
        console.log("price : " + price.innerHTML);
        totalPrice += parseFloat(quantity.value) * parseFloat(price.innerHTML);
    });
    var totalPriceElement = document.querySelector("#totalPrice");
    totalPriceElement.innerHTML = totalPrice.toFixed(2);
    console.log(totalPrice);
}

enter image description here

Total Price should be 2953.48, but 2952.00 is coming. I think there is a problem with float multiplications. how can i fix this?

    Please don't post code as an image. Type the text. Also include the actual HTML that drives the results you get from `querySelector[All]` calls. We should be able to just run your code "out of the box" and see the results you mention at the end. – trincot Aug 12 '22 at 12:51

  • Could you add the logs in order to have the same data as you? And try to log the data allready with the parseFloat – Edoldin Aug 12 '22 at 12:54

  • The reason for my question is 313.15 in the price section, so it does not see the comma when using js. stubbornly wants a point. – Hasan Polat Aug 12 '22 at 13:01

Your decimal formatting is a problem with parseFloat - replace the "," with a "."
