THRESHOLD may be any number more than 1. eveything 0 or more makes pretty much every number which is anything like another number equal... threshold is in count of bits... therefore for 1millionth digit accuracy that would be 20 bits. 10 bits is thousanths different are near 0 bits is if the same magnitude of number... but may be quite different -10 bits is thousands different are near 1 == 1.5 1 == 1.01
