Rooters,
I noticed that if I do
foo=new TF1("foo","sqrt(x)");
foo->SetRange(-10,10);
foo->Draw("C")
what I actually get is sqrt(abs(x)) drawn. Naively,
I'd expect to get zeros on the negative side of zero.
Is there a reason that this convention was chosen other
than a simple way to deal with errors from the sqrt function?
