Odd Numbers 
Jan 13 2007, 02:57 PM Post#1  
Posts: 16 Joined: 10January 07  I'm relatively new to access and have what I hope is a basic question. Can I get access to return numbers based on whether they are odd or even. What I want is to make a query that basically looks like this IIf ([Field]=Odd, yes, no) For Iif (Odd([field]), yes, no) (thats how I do it in excel) Any thoughts? Thanks a bunch

Use the Mod operator. IIf(8 Mod 2,"Odd", "Even" )

So 8 Mod 2 is dividing 8 by 2 and there is no remainer so the result is 0. An odd number will always have a remainder 7 Mod 2 will be 1 From Access VBA Help<

Posts: 1 Joined: 1May 14  Hi Everybody, This is my first post so I hope all is well! Just want to ask why did the IIF statement return a false value on this IIf(8 Mod 2,"Odd", "Even" ) when there is no logic operator? I'm sorry for the question but I really don't get it and by the way I'm a rookie..... hehehehe! Thanks in advance!

This takes advantage of the convention in programming that 0 = FALSE and [any number other than 0, though usually 1 or 1] = TRUE. Odd numbers will have a remainder of 1  so this is evaluated as TRUE So, the expression essentially says: IIf(TRUE,"Odd", "Even" ) Even numbers will have a remainder of 0  so this is evaluated as FALSE So, the expression essentially says: IIf(FALSE,"Odd", "Even" ) hth, d
