what i am saying is that your system will not distinguish between e and
(e+5*10^-k) and will make the same choices for both values. if it doesn't
matter that it makes the same choice for both values, you don't really need
to store e to k significant digits, so using an analogue system gets you
nothing. if it does, there is nothing you can do. which ever component makes
a decision based on the voltage value it's supplied from another component
will not be able to distinguish the two. (by voltmeter i did not mean an
external debugging device. i meant another part of the system)

this makes no sense to me.

we are talking about non quantum computer, and the noise is very simply
electro-magnetic waves generated by everything around your system.
(including all the sub-parts of the system)

sorry, this is obviously not sl4, and i will stop here.
