I have a range of randomly generated, positive whole numbers and need
to count the even values.

I assumed something like =SUM(--(ISEVEN(A1:A100))) entered as an array
formula would work, similar to entering =SUM(--(ISBLANK(A1:A100))) as
an array formula counts the blank cells within the referenced range.

But using ISEVEN in this manner returns #VALUE!

Is there another way to do this?

Thanks.
