i mod 2 gives you the remainder from dividing by 2. If there IS a remainder
- meaning i mod 2 is not equal to zero, and therefore "true" - then the
number is odd.

I have a cfloop that loops 6 times, I want to be able to be
able to output what loop number the current loop is on, and
tell if the number is even or odd.
You can use the MOD operator, in conjunction with the current loop iteration
value:
cfloop index="i" from="1" to="10"
Row
cfif #number# mod 2 eq 0
I'm even
cfelse
I'm odd
/cfif
I dont remember CF's mod operator, but I'm sure there is one.

cfset x="1"
cfloop index="count" from="1" to="6" step="1"

cfset x=x+1

Now just add a condition in there. It makes it easy since you know that you
Try the Mod() function. It returns the remainder of a division. Any even
number divided by 2 is 0 so
cfif LoopNumber mod 2 is 0
LoopNumber is even
cfelse
LoopNumber is not even (odd)

Take a look at the MOD operator in CF help. Basically, if INDEX MOD 2 = 1,
then the number is odd.

Increment a counter inside the loop, and check the value of counter MOD 2.

You want to use 'Mod' - can't find it in the help doco, but if you run the code below
you should be able to figure out whats happening
CFOUTPUT
CFLOOP FROM="1" TO="6" INDEX="i"
#i# is
CFIF i Mod 2
even
CFELSE
odd
/CFIF
BR
/CFLOOP

To find out if a number is Odd, use BitAnd()
BitAnd(nYourNumber,1)
If nYourNumber is Odd, BitAnd() will return 1, else it will return 0.

Use the following code as an example, the function you should look at is MOD
cfloop from="1" to="6" index="currentnumber"
cfoutput
The number : #currentnumber# is cfif (currentnumber MOD

If your loop is using a numeric index that is incrementing, use that
(assuming it starts at "1"), otherwise, set a counter variable to one before
the loop begins, then increment it on each pass. To detect whether it's odd
or even: CFIF counter_var MOD 2 IS 0 it's even CFELSE it's odd/cfif or
use
cfset thisnum =1
cfloop
cfif thisnum is 2do this/cfif
Blah Blah
cfset this num = #thisnum# + 1

Use the MOD operator
An even Number will return a 0, and odd number will return a 1

Pardon the possible duplicate post.
I prefer this method to the other solutions provided because it is a
standard style function.
To find out if a number is Odd, use BitAnd()
BitAnd(nYourNumber,1)
If nYourNumber is Odd, BitAnd() will return 1, else it will return 0.

Jason didn't say WHY he cared about even or odd, but if you want to use it
to make every other row a different color, a great "trick" is to include
the digits "0" and "1" in style class names and then use the MOD value to
pick which style without ever having to use CFIF
You just define style
