How do I determine if a number is even or odd?
An even number is any number that can be divided by 2 with no remainder. ColdFusion provides a function, mod, that returns the remainder of a division operation. To determine if a number is even, simply see if the value, modded by 2, returns 0:
<cfset x = 5>
<cfif x mod 2 is 0>
The number is even.
<cfelse>
The number is odd.
</cfif>
If the remainder is 1, then the number is odd.
