Having a div/0 error in excel 2007 return a 0 with in a large formula


I apologize if this is not considered real programming since it is in Excel but I need help and this is the most helpful place I know!

Alright so I have a very large if formula in excel:

=IF(AND(($EZ16+LF$1139)>$B$1145,($EZ16+LF$1139)<$B$1146),IF(OR(AND($FB16<LF$1141,$FB16>LF$1142),AND($FE16<LF$1141,$FE16>LF$1142),AND($FH16<LF$1141,$FH16>LF$1142),AND($FK16<LF$1141,$FK16>LF$1142),AND($FN16<LF$1141,$FN16>LF$1142),AND($FQ16<LF$1141,$FQ16>LF$1142),AND($FT16<LF$1141,$FT16>LF$1142),AND($FW16<LF$1141,$FW16>LF$1142),AND($FZ16<LF$1141,$FZ16>LF$1142),AND($GC16<LF$1141,$GC16>LF$1142),AND($GF16<LF$1141,$GF16>LF$1142)),FALSE,(EU16/EI16-1)),FALSE)

What can I do to it so that if it returns a div/0 error it will pass a value of 0 instead of the #DIV/0! error?

Would it be something like:

=IF(ISERROR(A1/B1),0,A1/B1)

If so how can I add that to my current formula and not break it? Would it be:

=IF(ISERROR(IF(AND(($EZ16+LF$1139)>$B$1145,($EZ16+LF$1139)<$B$1146),IF(OR(AND($FB16<LF$1141,$FB16>LF$1142),AND($FE16<LF$1141,$FE16>LF$1142),AND($FH16<LF$1141,$FH16>LF$1142),AND($FK16<LF$1141,$FK16>LF$1142),AND($FN16<LF$1141,$FN16>LF$1142),AND($FQ16<LF$1141,$FQ16>LF$1142),AND($FT16<LF$1141,$FT16>LF$1142),AND($FW16<LF$1141,$FW16>LF$1142),AND($FZ16<LF$1141,$FZ16>LF$1142),AND($GC16<LF$1141,$GC16>LF$1142),AND($GF16<LF$1141,$GF16>LF$1142)),FALSE,(EU16/EI16-1)),FALSE))**),0,IF**(AND(($EZ16+LF$1139)>$B$1145,($EZ16+LF$1139)<$B$1146),IF(OR(AND($FB16<LF$1141,$FB16>LF$1142),AND($FE16<LF$1141,$FE16>LF$1142),AND($FH16<LF$1141,$FH16>LF$1142),AND($FK16<LF$1141,$FK16>LF$1142),AND($FN16<LF$1141,$FN16>LF$1142),AND($FQ16<LF$1141,$FQ16>LF$1142),AND($FT16<LF$1141,$FT16>LF$1142),AND($FW16<LF$1141,$FW16>LF$1142),AND($FZ16<LF$1141,$FZ16>LF$1142),AND($GC16<LF$1141,$GC16>LF$1142),AND($GF16<LF$1141,$GF16>LF$1142)),FALSE,(EU16/EI16-1)),FALSE))

Thank you for the help!

EDIT: Tim a tried your suggestion:

=IF(AND(($EZ16+LF$1139)>$B$1145,($EZ16+LF$1139)<$B$1146),IF(OR(AND($FB16<LF$1141,$FB16>LF$1142),AND($FE16<LF$1141,$FE16>LF$1142),AND($FH16<LF$1141,$FH16>LF$1142),AND($FK16<LF$1141,$FK16>LF$1142),AND($FN16<LF$1141,$FN16>LF$1142),AND($FQ16<LF$1141,$FQ16>LF$1142),AND($FT16<LF$1141,$FT16>LF$1142),AND($FW16<LF$1141,$FW16>LF$1142),AND($FZ16<LF$1141,$FZ16>LF$1142),AND($GC16<LF$1141,$GC16>LF$1142),AND($GF16<LF$1141,$GF16>LF$1142)),FALSE,IF(EI16=1,0,EU16/EI16-1)),FALSE)

Still getting a #DIV/0 error, any idea why?


Solution

  • =IsError(100/0) will return TRUE, so make the conditional before to output 0, =IF(IsError(*),0,...)
