Negative Cube roots...Bug or not?

If you try to take a cube root of a negative number in C2 - for instance (-8)^(1/3), the answer should be -2.

If I try to do this operation in C2 though, it comes out as NaN. Reading up on it, I'm seeing that this is an issue in some other programming languages, and I'm wondering if this is something that's possible to fix in C2 or not - It seems pretty fundamental.

Assuming this can't be fixed...does anybody have an easy workaround for this?

The exponents are calculated with the Math.pow javascript function. Looking here it says for negative bases the result is always Nan when the exponent is less than 1.

It has further links to get into the nitty gritty why that's so. It says it has to do with precision issues.

Doubt it will be something to fix.

For just cubed root you could do something like this:

x = any number

sign = (x>0)-(x<0)

result = sign*abs(x)^(1/3)
