> The following files have something like:

> \applications\accounting\src\org\ofbiz\accounting
> \invoice\InvoiceServices.java (11 matches)
> \invoice\InvoiceWorker.java (4 matches)
> \payment\PaymentWorker.java

> \order\OrderReturnServices.java
> \shoppingcart\CheckOutHelper.java
> However BigDecimal already provides a constant BigDecimal.ZERO (as well as BigDecimal.ONE which are both inherited from superclass BigInteger) such that doing this is unnecessary (but not incorrect) and just creates more objects. The scale of the mathematical results will not be unaffected, as described in the JDK.

> There is no BigDecimal.ZERO. I tried compiling, got an error, looked at the javadoc and realized it is only BigInteger.ZERO. We're better off setting a static ZERO ourselves somewhere, preferably at the top of the Java file along with the scale and rounding mode.
> Look at InvoiceServices.java for example. Also, I was setting the scale of zero out of paranoia in that code, it probably isn't necessary.
> ===================================================
> Re-factor the following to use arithmetic.properties instead of setting them directly:
> org/ofbiz/accounting/tax/TaxAuthorityServices.java: taxTotal.setScale(2, BigDecimal.ROUND_CEILING);
> org/ofbiz/accounting/tax/TaxAuthorityServices.java: priceWithTax.setScale(2, BigDecimal.ROUND_CEILING);
> org/ofbiz/accounting/invoice/InvoiceWorker.java: invoiceTotal = invoiceTotal.add( amount.multiply(quantity)).setScale(2,4);
