difference between blank and zero ....

rather than 0.

Is this behaviour to be expected? If so, is there an elegant way to handle
cells with a blank value, as having "0.00" all over the sheet is a bit untidy?


Something like:

=if(ItemPrice="","",YourFormula)
--ron

The difference is in what functions and type of formula you're using. Some
functions evaluate an empty cell as 0 and some functions ignore empty cells.
In the case of MIN, it ignores empty cells unless *all* of the cells
referenced are empty then it will return 0.

How you deal with it depends on the application.

If you want this to return 0 when "price" is empty:

MIN(price,75)

Try it like this

MIN(price*1,75)

Both MIN and MINA functions/formulas ignore BLANKS...

If you want to treat a blank as a zero and get MIN as zero then try
=MIN(IF(A1:A100="",0,A1:A100))

This will convert all blanks to 0 in the range A1:A100 and then pass it to MIN

Clarification:

In the case of MIN, it ignores empty cells unless *all* of the cells
referenced are empty then it will return 0.
MIN(price,75)

Ok, you might think: well, "price" is *all* of the referenced cells so why
doesn't it evaluate as 0?

Because 75 is another argument that isn't an empty referenced cell. So, I
should have said:

....it ignores empty cells unless *all* of the referenced arguments are empty
cells then it will return 0.

Ah, the irony. Straight after I posted, I see the other post "Cell is not
blank" - serendipitous.

Thanks, Biff. The "*1" has done the trick.

Each occurrence of the formula references a single target cell (albeit three
times), not a range, so this was the easiest fix.

=ROUND(MIN(E29*1,75)*0.0525+(MIN(925,MAX(E29-75,0)))*0.0275+MAX(E29-1000,0)*0.015,2)

only needed the first term modified.

You're welcome. Thanks for the feedback!
