Determining Even and Odd numbered Pages

This is a general programming question. I'm actually using it in Crystal Reports, but it's just the logic that I need.

I want to say if the pagenumber is odd-numbered then do X, if it's even-numbered then do Y. I just can't find a good mathematical way of figuring that out.

For example, if [pagenumber] is divisible by 2, then it's even. And if [pagenumber] is NOT divisible by 2, then it's odd. But that doesn't really work. Anyway, there must be a simple way of doing this. Maybe using the '%' operator??

Thank you for your help!!

Try using the modulas operator (MOD). MOD command find the remainder of one number divided by another

For Example,

OddEven = PageNumber MOD 2

Or use it in an If...Then,

If (PageNumber MOD 2) = 0 Then 'zero remainder
'even page
Else
'odd page
Endif
