    cur_obj = self.pool.get('res.currency')
    res = {}
    if context is None:
        context = {}
    for line in self.browse(cr, uid, ids, context=context):
        if line.amount_discount:
            price = line.price_unit - (line.discount or 0.0)
            taxes = tax_obj.compute_all(cr, uid, line.tax_id, price, line.product_uom_qty, line.product_id, line.order_id.partner_id)
            res[line.id] = taxes['total']
        if line.invoice_ids:
               cur = line.invoice_ids.currency_id
               res[line.id] = cur_obj.round(cr, uid, cur, res[line.id])  
            price = line.price_unit  * (1 - (line.discount or 0.0) / 100.0)
            taxes = tax_obj.compute_all(cr, uid, line.tax_id, price, line.product_uom_qty, line.product_id, line.order_id.partner_id)
            cur = line.order_id.pricelist_id.currency_id
