i'm not quite sure how to do this but i need to trim after two decimal places. say like:

359.96999999999997 -- keep .96 and drop all others so the result would be:

359.96


function cal() {
      var price = 119.99; //product price
      var quantity = document.orderform.txtbxQuantity.value; //3
      var qtyPriceTotal = price*quantity; //359.96999999999997 -- keep .96 and drop all others
      document.orderform.txtbxCalculatedAmount.value = qtyPriceTotal;

	  var shipCost = 9.00; //shipping cost
	  var shipqty = shipCost*quantity; //3*9=27
	  var subTotal = qtyPriceTotal; //359.96999999999997
	  
	  var total = shipqty+subTotal; //386.96999999999997
	  document.orderform.txtbxTotal.value = total; //386.96999999999997
 	  document.orderform.txtbxTotal2.value = total; //386.96999999999997
}

      var quantity = document.orderform.txtbxQuantity.value; //3
      var qtyPriceTotal = price*quantity; //359.96999999999997 -- keep .96 and drop all others
      document.orderform.txtbxCalculatedAmount.value = qtyPriceTotal;

	  var shipCost = 9.00; //shipping cost
	  var shipqty = shipCost*quantity; //3*9=27
	  var subTotal = qtyPriceTotal; //359.96999999999997
	  
	  var total = shipqty+subTotal; //386.96999999999997
	  document.orderform.txtbxTotal.value = total.toFixed(2); //386.96999999999997
 	  document.orderform.txtbxTotal2.value = total.toFixed(2); //386.96999999999997
