Your numbers should not appear as 32. or 16. And if anyone types your input into Mathematica, the results are 4 Sqrt[3]. You must have some hidden characters in there, or you did something very strange with Precision and Accuracy. Mathematica has problems with numbers if you are used to conventional interpretations as in Fortran or C. -- Richard J.
