Using Modifier discount % is applied - how to control the calc to 2 digits after the decimal

Hi Pricing guru's

We have a credit scenario like below

List price -- 100

Discount Modifier: 52.125

Net amount will be paid to customer.

While calculating the amount paid to the paid to customer, as normal functionality the discount is calculated with 5 digits after decimal --- where as we need the discount to be restricted to 2 digits after the decimal...

Please suggest options that i should check to get this functionality for this scenario.

Thanks and Regards,

Srini
