YOU'RE PAYING TOO MU
Nathan,
I think you're a little off in your interpretation.
3 ^ 3 = 27 ( 3 x 3 = 9, 9 x 3 = 27)
27 ^ (1/3) = 3

You're right. On both counts. It would have to be an nth root, so easier

Here it goes (I started with David Gassner's code and here is what I
have.)

Since everyone else has taken a stab at it, this is how I would do it:
There aren't that many powers of three, so I think it would be quicker to pick
it out of a list.

Notcing a few posts go by today, I thought I'd expand by saying that _IF_
you know the upper limit to these number then the best thing to do is a
Okay, Okay, Quick Question can you give us a hint as to why you want this?

I guess you could run a loop and keep dividing by 3 until the final number
is either 1 or has a decimal

in that case, I'd have to go with Courtney on this one. you could do a "3
EXP counter" comparison, too (using her logic structure).

of times a number is
divisible by 3 also happens to be divisible by 3, though.

It's not very elegant, but the most efficient method (assuming it's always 3
that you care about) might be to put all the values you care about into a
list in the application or request scope and do a listfind. You can't have
that many entries before you hit the CF biggest-number limit.

Umm. Take it's cubed root? See if the fraction is other than 0?

I have a loop that needs to fire an event at every power of three that it
