Hello,
The operator ^ seems to return the real part of one of the complex roots of x^3=1.
If x=[-10:1:10]
and
y = x^(1/3);
Thus, for x<0, the values of y are half the opposite of values obtained with x>0.
With y=x.^(1/3), the values of y are complex for x<0.

I have problems to graph the function
x=[-10:1:10]
y = x^(1/3);
plot(x,y);
the same in plot of google gives a graph but scilab does anything with the sign.
