How to Add Decimal Quantity to WooCommerce

Today we are going to talk about adding decimal quantities in WooCommerce. You have to paste the following function in your active/child theme’s function.php file.

// Add min value

add_filter('woocommerce_quantity_input_min', 'decimal');
function decimal($val) {
    return 0.1;
}

// Add step value to the quantity field

add_filter('woocommerce_quantity_input_step', 'allowDecimal');
function allowDecimal($val) {
    return 0.1;
}

// Removes the WooCommerce filter

remove_filter('woocommerce_stock_amount', 'intval');

// Add a filter

add_filter('woocommerce_stock_amount', 'floatval');

// Add unit price fix

add_filter('woocommerce_order_amount_item_total', 'unit_price', 10, 5);
function unit_price($price, $order, $item, $incTax = false, $round = true) {
    $qty = (!empty($item['qty']) && $item['qty'] != 0) ? $item['qty'] : 1;
    if($incTax) {
        $price = ($item['line_total'] + $item['line_tax']) / $qty;
    } else {
        $price = $item['line_total'] / $qty;
    }
    $price = $round ? round( $price, 2 ) : $price;
    return $price;
}
