{Precision@N[2^1024],N[2^1024]===$MaxMachineNumber}

on my computer, this command gives {15.9546,False} However, I think the result is supposed to be {MachinePrecision,True} Is there something wrong with N? My computer is an Athlon XP running Windows XP SP2. Also, why does ByteCount@$MaxMachineNumber give 16 ? I'm sure I am missing something, but I thought a double precision floating point number would only take up 8 bytes. Thanks. -- http://chris.chiasson.name/
