Sumproduct

[Guest]

Hi, can anyone inform me the reason for using the "--" in formulas
(especially the sumproduct function)

Someone referred me to this link but I cannot decipher HOW the formula works.

hi

the double unary "--" which converts text value into numeric
is mostly used for ignoring errors..!!

Not really mate, it is used to coerce True/False arrays into 1/'0 arrays
which can then be summed.

No, it is used to coerce True/False arrays to 1/0 arrays. SP is generally
used to test multiple conditions, and these tests return an array of TRUE or
FALSE. This is of no use to get a count, so that needs to be changed to
arrays of 1 and 0, which is what the double unary does.
