Bug in iteration for complex numbers

Hello everyone,

Correct me if I am grown but I think the calculations for this applet are incorrect when z_0=i.

https://www.geogebra.org/m/tEetDqXF

The values should be as follows

z_0=i

z_1=-1+i

z_2=-i

z_3=-1+i

z_4=-i

further iterations will just repeat the values -1+i and −i. But in the worksheet you can see that this is not the case and shows that the orbit is unstable, which is incorrect.

I also checked it in the desktop and online version. Both have the same issue.

I hope you can help me with this. Thanks in advance. :)

Thanks, we'll check. for now if you change

z^2


to

z * z


then it will work better
