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.
Thanks,
Ted Ersek
