If this is done by setting all bytes of the memory to 0, this doesn't
necessarily map to 0.0 in the floating point formats of all machines.
If the ntp code does something more clever (like knowing that a certain
address range is an array of doubles), it might still work if you make
sure the assumptions of that clever code still holds.
