Opposite of raisedToInteger: or raisedTo:

Hi , I am new to pharo smalltalk and need a method opposite to raisedToInteger: or raisedTo: in order to calculate more roots than sqrt. I can only see the sqrt method but looking for a method that can calculate n roots.
Any immediate help would be appreciated.
Thanks

#nthRoot: anInteger is your friend.

i.e.:
256 nthRoot: 8 "will return 2"

Re: Opposite of raisedToInteger: or raisedTo:

Is there any method that does this in Pharo?

Yes, again, #nthRoot: :)

It is available in Pharo 1.4 at least.

Did you try evaluating "27 nthRoot: 3" in a Workspace?

Are you sure you're using Pharo 2.1? Because there is no such version (yet).

In Pharo 2.0 there is a #nthRoot: method. I don't know what will happen with in the v2.1, but I'm pretty sure it will remain there.
