Usually order sum rounding is used to speed up the service and convenience of customers by discarding pennies, or as a legal requirement. For example, if ResultSum is 1320.74, the callback may return -0.74 to round the sum down to 1320, or return 0.01 to round the sum up to 1320.75 (to the nearest multiple of 0.05).
