I'm having an annoying little problem with version 4.0.1.0. I wrote the following info in a notebook and ran it: Clear[v2] v2 = {4, 0, -6} N[Sqrt[v2.v2]] N[Sqrt[v2.v2], 3] Now the third line gives me 7.2111 but the fourth line gives me the same instead of 7.21. Does anyone have any idea what may be the problem? Am I doing something wrong? thanks, Nalanji Dreaming
