Although there seems to be not much interest in polynomial rootsolving, here's finally my program for the WP34s - maybe at least a few members here will like and use it. ;-)

I've put it in the Article section:

Now I've also put the file in my download folder:

If you have any remarks, suggestions or questions about my program feel free to post them here. Of course also if you find any polynomial(s) where my program fails or gives wrong or inaccurate results - although this is very unlikely. ;-)

Just in case you need a polynomial rootsolver for the PC, or if you want to test my WP34s program - here's a very interesting website about polynomial rootsolving, which has programs for the PC and also an online rootsolver:

There's also still the previous version of this 'RootFinder' program available (WinSolve), which has the advantage that it doesn't need .NET4, so this is my prefered version:

Merry Christmas to all,
