Round uses Banker's Rounding. That means if the last digit is 5 the rounding
takes place toward the nearest even number so .235 rounds to .24 and .245
rounds to .24. The theory is that this will be closer to the correct amount
if you round a lot of numbers.

There are other rounding algorithms that will round the way you wish.

John,

I appreciate the respond and it works however, I have one more question if
we have a number/currency like 10.325 and we round it to two decimal place as
you suggested would this number be 10.32 or 10.33. Access is giving me 10.32
I thought in math anything 5 or above should be rounded to the next number,
does Access think the same way. I do see 10.33 if I round the field in the
report into two decimal place under the field properties by not using the
formula of Round([exp],2).

Thanks again

The problem is that Taxes needs to be rounded off during the calculation.

Taxes: Round(([matsales]+[scharge])*0.0875,2)

AND when you sum
SUM(Round(([matsales]+[scharge])*0.0875,2))

Otherwise small discrepancies are going to creep into your calculation of the
Total Tax. You may see 0.39 for the calculation [matsales]+[scharge])*0.0875
but the actual result may be 0.39375. When you total a few like that before
rounding you end up with extra pennies. On the other hand .3965 will display
as .40 and total a few of those and you might loose a penny or two.

I have a report that feeds of a query. The query has the following fields
matsales: [order details]!unitprice*[order details]!quantity
scharge: [order details]!surcharge*[order details]!quantity
Taxes: ([matsales]+[scharge])*0.0875

0.0875 is that tax values

On the report the sum in the footer =Sum(matsales) and = Sum(scharge) are
correct however, =Sum(Taxes) is off. For example the total should be $161.88
after the taxes has been rounded off in two decimal places but its giving me
$161.85 the actual total if the taxes were not rounded off.

The matsales and scharge total are correct and they are rounded as well. I
think the problem im having is similar in excel if its not "Set as precision
as displayed."
I have tried every possible format in both the sum field in the report and
query, I even converted the numbers to CSng or Cdbl. Tried rounding off the
quesry as well, and none worked.

Is there a way on access to sum the values as displayed if not is there a
solution for the problem I described above.

Thanks
