In Excel formulas everything is a function. IF, AND, OR, NOT are all functions. It is awkward and goes against what software devs are familiar with, but there are probably more people familiar with the Excel IF function than any other forms. Here is an example taken from the docs... =IF(AND(A3>B2,A3<C2),TRUE,FALSE)

Excel cell formulas are the most widely used functional programming language in the world.

Yes I stand corrected - we were using C so definitely not a function there.
