 Well,  40115 of the little devils would do it... Actually,
that would give accuracy to about 1 part in 10^8.

Sort of like the time a friend was bar hopping years ago, here
in Silicon Valley. He ran into this girl who worked in mark-and-pack
at the end of the assembly line at a local I.C. manufacturer. They
talked a while, maybe even on a coule of nights, and she told him
that she could "get him any I.C.s he wanted", right off the line.
Well, "Hell!" he says; why not. Tells her he could use whatever
7400s she could get. (Yeah this *was* a while back!) Couple weeks
later, he runs into her again and she says that she has something
in the car for him. Yep. About 2000 Seventy Four Zero Zeroes...

Now, isn't there a theorem that proves that you can build ANY logic
system, using only 2-input NAND gates?

(Oh yeah - spoiler:


    Put 113 strings in parallel, each with 355 1 Ohm resistors...)
