cubic root [message #83966]

Hi all

I have a question about cubic roots. The cubic roots of a negative number there exists. The cubir root of -1 is -1, 0f -2 is -1.25 and so on why when I typed in IDL to calculate the cubic root of a negative value it print out NaN which means Not a Number?

E.g. I typed: (-1)^1.0/3 and it prints out NaN

Is there any way to fixed it and don't get NaNs but get the actual value?

Best Wishes
Maria
