XMLP Rounding issue vs Excel???

Question

Hey all,
We're modifying the Sales Order Acknowledgement using XML Publisher for an australian business unit. The standard Sales Order Ack has just the line total, but we need to break out GST tax and show it separately.
GST calculation is original price plus 10%. For example a cricket bat for $250 would be $250 plus $25 GST. Total cost of $275.00. When rounding i.e. $17.356666 this would be$17.35. You must round down.
Here is an example of what we are trying to accomplish:
The formula is as follows:
In the Unit Selling Price: <?xdofx:round( (SELLING_PRICE) div (1.1),2)?>
In the GST column: <?xdofx:round( (SELLING_PRICE) div (11),2) *C_ORDERED_QUANTITY?>
This is not producing the correct output.
Our developer has moved on, but his last comment to us was this:
Regarding Sales Acknowledgment, there is discrepancy on rounding between excel and xml publisher. Excel rounds .35 where as xml rounds it to .34 and oracle db also calculates to .34.
Can anyone shed some better light on this subject?

Answer 1

Well, you could make sure you never have costs > $10,000 and that would solve it!

Okay, couldn't resist.
What about trying to change the default formatting for that folder's item in Disco Admin against the EUL directly (ie: setting the format to none like you found, or setting it to 2 digit accuracy, etc.) and see if that works.
