 MrExcel Message Board :: View topic - double minus sign in clever SUMPRODUCTS
One of the, if not the, fastest and most efficient ways is to use two negation operators together, which changes the sign twice, resulting in a numeric value.
My understanding of the double unary is that the first “-” converts true/false to -1/0 (True = 1, false = 0) and the second “-” changes the sign to 1/0.
If you go to the thread referred to by Paddy, and remove the double unary from the Sumproduct formula, the answer is 0 (zero).
