Dashes in Functions
They're just minus signs. By applying a unary minus operation to a
true/false, you force Excel to turn the booleans into numbers. By applying the minus twice, you get back to a positive number. So --(true) is 1; --(false) is 0. "LPS" wrote: Has anyone ever seen the use of "dashes" in functions or formulas before? I have a user who has several instances where dashes have been used (someone sent her the spreadsheet) and none of us have ever seen this before. An example follows: =SUMPRODUCT(--(F3:F838<121),--(E3:E838=1)) Any suggestions / explanations? Thanks, -- LPS |
