[ePiX-users] How to plot x^(1/5)

[Gunnar]

Hello.

I've tried that with the function


double g5(double x) {
        if (x==0)
                return 0;
        else
                return exp(log(x)/5);
}

and plot with

plot(g5,Xmin,Xmax,80);

but the curve doesn't look very smooth for x small. 
Any suggestions?
I use ePiX 1.0.20 and gcc 4.1
Thanks, Gunnar.
