This is some interesting:



-8^(1/3)

[1] -2

x=(-8:8)

y=x^(1/3)

y

  [1]      NaN      NaN      NaN      NaN      NaN      NaN      NaN      NaN
0.000000 1.000000

[11] 1.259921 1.442250 1.587401 1.709976 1.817121 1.912931 2.000000



So, can anybody explain this?! (Why is x[1]^(1/3)=y[1]=NaN, but
-8^(1/3)=-2?)



Thx!!!
