Hi, of course are Mathematica programs hardware dependent, if they use the processor arithmetic units. And there are differences, if you use a 16, 32 or 64 bit processor. or a 586, ppc or a xyz processor Mathematica runs on (...for 8 bit Mathematica was not implemented, as far as I know...). If you define a arbitrary precision, Mathematica is not (so much...) hardware depended.

Mathematica 5.0 AC: Could you please elaborate on your comment ... > Because MachinePrecision depends on the underlying hardware > architecture, Mathematica programs are hardware dependent! I had the notion that any problem could be set-up in Mathematica using variables with arbitrary (user-specified) precision, but perhaps I misunderstand the passage where I read this. Please help me clarify this. Harold
