I am trying to Round a group of numbers and then add up thei
values...any ideas??? FOR EXAMPLE...i have the following numbers...

100,324.51
53,213.76
34,527.33
344,869.50
18,803.66
241,406.10
2,299.88
38,171.09
183,350.12
71,334.89
66,924.06
472,549.11
166,470.45
215,908.16
34,572.53
52,408.16
251,905.22
59,723.59
20,782.59
131,984.95
334,036.00
3,638.02
30,650.25
314,257.83
46,297.56
*3,290,409.32 * <= They need to add up to this

Now if you actually did add all those numbesr up it would come ou
right...except those values actually are a lot longer than just
digits after the decimal...so sometimes when i sum those up...i am of
.01 or.02 give or take...so what i want to do in the total cell i
round all the numbers to 2 decimal places and and those values up...i
this possible?

Thanks!

Hi,

Assume data is in A2:A26:

=SUM(ROUND(A2:A26,2))

This needs to be confirmed with Ctrl + Shift + Enter because it is an
array formula.

When I add up those numbers I get a different answer:

3,136,871.05


But that's probably due to a typo or a missing value in what you posted.

In any event, to ROUND to two decimals and then SUM the result, use the
following *array-entered* formula:

=SUM(ROUND(A1:A24,2))

To *array-enter* a formula, after typing or pasting the formula into the
formula bar, hold down <ctrl><shift> while hitting <enter>. Excel will place
braces {...} around the formula if you did it correctly.

Aaah, the old 'customer doesn't think you can add problem'. I've had the
same with pricing issues myself.

Try :

=SUM(ROUND(A1:A13,2)

Then hold down the CTRL + SHIFT keys as you press the ENTER key. This will
create an "array formula". The result will look like {=SUM(ROUND(A1:A13,2)}
in your formula bar.
