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 as
others have suggested and precompute them all (for n=1 to upperx; x=n^3;
next; ).
Put the precomputed numbers in a list. Just do a lookup and match into the
list.
If you have no idea beforehand what the upper limit will be you'll have to
do a cube root in cf. I've never tried that. Not sure if you can. Um....
sec.... oh yea, Tom Numaker has a tag. CFX_Functions. I think it does cubed
roots.
Maybe not. Seeing exponents, but no roots.

Oh well. Perhaps you could use a bit of algebra and get the same effect with
the exp function though. ;-)
