Question : MS Access Report (NZ Function)

I have a simple report which is just 3 columns of numerical data, which some values are null.  The 3rd column is the difference of the 1st 2.  I am using the NZ function in the query, so I would get a 0.00 in the report where there is no data (Expr1: NZ([fieldname], 0).  The problem is for the columns in the report that contains those values from the NZ function, I am unable to format to 2 decimal places.  It actually shows up to 13 decimal places.  And those that are round numbers, show no decimal places.  

If I do not use the NZ function in the query, the formatting to fixed and 2 decimal places works.  Are there any other options so I get 2 decimal places and zero values in place of the nulls?

Answer : MS Access Report (NZ Function)

You could do the formatting in the reports controls rather than in the query.

In query you could try:
Expr1: format(NZ([fieldname], 0), "0.00")
