VPL doesn't calculate cube root

Question

I was trying to calculate cube root using VPL:

What I'm doing is setting the value to the power of 1/3

And as a result it gives me 1 all the time. Where the problem could be? Thank you.

Answer 1

I bet 1/3 is getting truncated to 0, because the numerator and denominator are both integers. Any number raised to the 0 power gives 1.

If you use 1.0/3.0 instead, it might work.
