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? -- RAINMAN "How much does a piece of gum cost Ray?" "About $100."
