What is this array formula calculating

[aghampton]

I recently had responsibility of a spreadsheet passed down to me, and there's an array formula used that is labled "increase count". Here is the formula: {=SUM(IF(G89:G118>S89:S118,1,0))} Columns G and S have various dollar amounts for sales in them, so the actual sum of them is a very large number, the the formula is returning a much smaller number. I just want some help understanding what this formula is calculating, if possible.

It's counting the rows where column G is greater than column S (between rows 89 and 118).

{=SUM(IF(G89:G118>S89:S118,1,0))}
It is comparing each row in pair, i.e, G89>S89, counts 1, G90<S90, counts 0, then cumulative suming up.

Another non-array version, normally enter:

=SUMPRODUCT(--(G89:G118>S89:S118))
