double unary
Thank you to who ever suggested this site
http://www.xldynamic.com/source/xld.SUMPRODUCT.html But I am still unclear on which unary or operator to use, ,--, *, +, - I understand by using an arithmetic operator you will get the result of additions or subtractions. Here is what I'm up against. I want to count the number of N's and U's in (column AH), that fall in the month of July (Column AX) and contains a number in (column AM) =SUMPRODUCT(--(Odyssey!$AH$2:$AH$999="N")+(Odyssey!$AH$2:$AH$999 ="U"),-- (Odyssey!$AM$2:$AM$999<"")*(Odyssey!$AX$2:$AX$999 =DATE(2006,7,1))*(Odyssey! $AX$2:$AX$999<=DATE(2006,7,31))) I am getting the correct results I just want to understand why I used * between the dates and + between N and U and -- and the start of the formula. Thanks again -- Message posted via http://www.officekb.com |

For the double - you can find a clear explanation he http://mcgimpsey.com/excel/formulae/doubleneg.html while * is the equivalent of the AND operator and + is the equivalent of the OR operator. So your formula could work also in this way: =SUMPRODUCT(((Odyssey!$AH$2:$AH$999="N")+(Odyssey! $AH$2:$AH$999="U"))*(Odyssey!$AM$2:$AM$999<"")*(O dyssey!$AX$2:$AX$999=DATE(2006,7,1))*(Odyssey!$AX $2:$AX$999<=DATE(2006,7,31))) -- Hope I helped you. Thanks in advance for your feedback. Ciao Franz Verga from Italy |

Who knows why you used it? I certainly don't (well actually I do, but it is
not necessary (see later). I quote from that article, ... There is no situation that I know of whereby a solution using -- could not be achieved somehow with a '*'. Conversely, if using the TRANSPOSE function within SUMPRODUCT, then the '*' has to be used. In your formula, -- would have worked where you have *,. As written, * would not have worked where you use --, because of the OR (+) condition, but just by wrapping extra brackets around the OR conditions, you could have used *. IMO, the worst you can do is mix them. You could even get rid of the + with =SUMPRODUCT(--(Odyssey!$AH$2:$AH$999={"N","U"}), --(Odyssey!$AM$2:$AM$999<""), --(Odyssey!$AX$2:$AX$999=DATE(2006,7,1))*(Odyssey!$ AX$2:$AX$999<=DATE(2006, 7,31))) -- HTH Bob Phillips (replace somewhere in email address with gmail if mailing direct) "s2m" <u23063@uwe wrote in message news:65346e330a7fa@uwe...

Excel is very forgiving.
I wouldn't have mixed and matched. I would have used separate arguments. =SUMPRODUCT(--((Odyssey!$AH$2:$AH$999="N")+(Odyssey!$AH$2:$AH$99 9="U")), --(Odyssey!$AM$2:$AM$999<""), --(Odyssey!$AX$2:$AX$999=DATE(2006,7,1)), --(Odyssey!$AX$2:$AX$999<=DATE(2006,7,31))) The + in the first line of that expression is acting like an "or". If AH#=N or AH#=U. But the * in the original formula are acting like "and"'s. Using the * or using separate arguments pretty much boils down to what you like. I like the separate arguments. I think it's easier to read/modify. s2m wrote: Thank you to who ever suggested this site http://www.xldynamic.com/source/xld.SUMPRODUCT.html But I am still unclear on which unary or operator to use, ,--, *, +, - I understand by using an arithmetic operator you will get the result of additions or subtractions.

=SUMPRODUCT(--(Odyssey!$AH$2:$AH$999={"N","U"}),
is the same as a or statement? Bob Phillips wrote: Who knows why you used it? I certainly don't (well actually I do, but it is not necessary (see later). I quote from that article, ...

Yes it is, it is saying if the range is equal to N or equal to U. Of course
if you are ORing different ranges, you need the other approach. -- HTH Bob Phillips (replace somewhere in email address with gmail if mailing direct) "s2m via OfficeKB.com" <u23063@uwe wrote in message news:6542e792abe6d@uwe... =SUMPRODUCT(--(Odyssey!$AH$2:$AH$999={"N","U"}), is the same as a or statement?
