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

  • To: mathgroup at smc.vnet.net
  • Subject: [mg80685] {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.
