Qty values are rounded down

Hello,

I rolled back to version 9.1.1 and the values in the cart are not rounded down anymore. The issue was happening with versions 9.2.0 and 9.3.1 (didn’t had the chance to try other versions).

In order to ger decimal values in the cart, we use the Min Max Step Quantity Limits Manager for WooCommerce plugin and also we added these to functions.php (please note that these functions were added after the issue with cart qty rounding):

add_filter( 'woocommerce_loop_add_to_cart_link', 'view_product', 10, 2 );

function disable_qty_field_for_specific_category($product_quantity, $cart_item_key, $cart_item) {
$parent_category_slug = 'piele-naturala';

// Get the product ID
$product_id = $cart_item['product_id'];

// Check if the product belongs to the specified parent category
if (has_term($parent_category_slug, 'product_cat', $product_id)) {
    // Return only the product quantity without the input field
    return sprintf('<span class="product-quantity">%s</span>', $cart_item['quantity']);
}

// Return the default quantity input field for other products
return $product_quantity;

}
add_filter('woocommerce_cart_item_quantity', 'disable_qty_field_for_specific_category', 10, 3);

add_filter( 'woocommerce_quantity_input_args', 'custom_decimal_quantity_step', 10, 2 );
function custom_decimal_quantity_step( $args, $product ) {
$args['step'] = 0.01;
$args['min_value'] = 0.01;
return $args;
}

add_filter( 'woocommerce_cart_item_quantity', 'allow_decimal_quantities_in_cart', 10, 3 );
function allow_decimal_quantities_in_cart( $product_quantity, $cart_item_key, $cart_item ) {

$product_quantity = wc_format_decimal( $cart_item['quantity'], 2 );
return $product_quantity;
}

Products with decimal qty values are all variable products.

Example: one product is available in 2.35, 4.30, 4.37 and 4.68 sizes. For the variations the min and max qty is set to it’s corresponding size and the qty field is disabled (so customers cant override the values). So, if a somebody wants choses the 4.37 size, then 4.37 qty is added to the cart.
