Round[Range[10]+.5] {2,2,4,4,6,6,8,8,10,10}T Of course every time run this, you will get the same answer. SO could you please send us an example where Round, in your own words: "doesn't give the same answer every time"? > It's one reason that makes me think Mathematica is not really > "Engineering Grade" I think the problem is just the opposite: some engineers are just not "Mathematica grade" mathematicians and programmers.
