Thomas: By default, Mathematica displays all results to 6 significant digits. Therefore, it rounds to 6 significant digits. To change the number of significant digits Mathematica displays (and rounds to), press Ctl+Shf+O to popup the Option Browser, select either Global or Notebook, and search for PrintPrecision. Then highlight the number 6, and change it (type over it) with your preferred precision (say, 10). Then click Apply, close the Option Browser, and recalculate your expression. You will now see results displayed (and rounded) at 10 significant digits. To see all of your results, use FullForm[result]. This will display all the significant digits Mathematica keeps. For this exercise, that number will be $MachinePrecision (~16) decimal digits. Regards, Harold
