Rounding in receipt

In RMS, 40column receipt format, i am using this code for transaction rows

<ROW> Entry.Description "|" Entry.Quantity "|" Entry.ExtendedExclsvPrice "|" Entry.Quantity*ExtendedExclsvPrice </ROW>

The problem is , when you give a discount RMS spreads the discount to the rows, and some strange numbers appear, like 4.234 , 3.167

This makes the customers confused about the retail prices.

I tried ceiling formula but didnt work .

How can I get rounded numbers in the transaction lines after discount. What formula should I use in the xml file for receipt?

Any help would be appreciated

Regards
