Mar 20, 2013 at 16:16 comment added acl @cormullion don't bother, I am just doing it out of boredom. all our answers are useless to the OP; what they need to do is learn basic mathematica syntax and complex numbers. But since everybody else is after my upvotes, well... :)

more silliness
Mar 20, 2013 at 15:37 comment added cormullion very nice; I feel I ought to delete my derivative answer now that you've started illustrating your own answer so well ... (But I don't think I will... :)

added link to tutorial on exact vs approximate numbers
Mar 20, 2013 at 11:50 comment added acl @nikie is correct; press F1 to bring up the help centre, then paste tutorial/ExactAndApproximateResults into the top bar to see this tutorial.
Mar 20, 2013 at 11:37 comment added Niki Estner @hhh: "0" is an exact number. "0." is a machine-precision number, and calculations with machine-precision numbers are much faster.
Mar 20, 2013 at 11:30 comment added hhh why do you the dot "0." in the term "NestWhileList[#^2+c &,0.,Abs[$]<escapeRadius&," and not "0"?
