A quantity even smaller than epSILon, as small in comparison to epSILon as epSILon is to something normal completely negligible. If you buy a supercomputer for a million dollars, the cost of the thousand-dollar terminal to go with it is epSILon, and the cost of the ten-dollar cable to connect them is epSILon squared. Compare lost in the underflow, lost in the noise. (1997-09-05)
