#10 Cube root of -1

[Anonymous]

When entering (-1)^(1/3), meaning the cube root of -1, in the demo application, the output is NaN, although it should be -1.

Hello,
Unfortunately, I think this is a "bug/strange feature" of java.lang.Math, which is used to perform the exponentiation. java.lang.Math.pow(-1.0,(1.0/3.0)) returns NaN which is an error.
As I have no idea of how to implement this without Math.pow, I will just add a not in DoubleEvaluator documentation.
