Jacques Le Roux commented on OFBIZ-4038:
----------------------------------------
Jeremy,
My apologies, the rounding was already present in the divide operation, so the
additional setScale wasn't necessary.
> Rounding error in prorating returned adjustments

> The error is in
> applications/order/src/org/ofbiz/order/order/OrderReturnServices.java the
> getAdjustmentAmount method is prorating using this code:
> newAmount = returnTotal.divide(originalTotal, decimals,
> rounding).multiply(amount).setScale(decimals, rounding);
> it should be:
> newAmount = returnTotal.multiply(amount).divide(originalTotal, decimals,
> rounding);
> else by dividing first what should be for example 1/3 of the adjustment ends
> up being 0.33
