• Arguments that contain TRUE evaluate as 1; arguments that contain FALSE evaluate as 0 (zero). 
• Array or reference arguments that contain text evaluate as 0 (zero). Empty text ("") evaluates as 0 (zero). 
• If an argument is an array or reference, only values in that array or reference are used. Empty cells and text values in the array or reference are ignored. 
• Arguments that are error values or text that cannot be translated into numbers cause errors.
