Richard Fateman states: > About using N[ ...,30] around everything... this may not work > because in Mathematica, f[N[...,30]] and N[f[...],30] are not the same. This is correct and reveals a subtle point about the use of N in Mathematica. Jerry Keiper's tutorial notes on this topic (available, as mentioned previously, directly from Wolfram Research) help to clarify this matter further. Paul C. Abbott
