third (odd) radical of a negative number

[Former user]

Originally reported on Google Code with ID 232 ``` (-8)^(1/3)

it is the third radical of -8

the result is -2, because -2^3=-8 but speedcrunch says NaN

I hope this issue isn't allready reportet, anyway i don't found it. ```

``` It has been reported in issue 55, and in addition, this behavior is explained in the speedcrunch documentation found in /doc. NaN is all Speedcrunch can give here ```
