Which if any platforms running Mathematica version 3 or 4 return something different for the following input. ----------- In[1]:= {N[2^-52] === $MachineEpsilon, N[2^-1022] === $MinMachineNumber, N[2^1024] === $MaxMachineNumber} Out[1]= {True, True, True} ------------- I understand this is the case for double precision on any computer which uses IEEE 754 floating point arithmetic.
