epsilon see delta 1. n. a small quantity of anything. "the cost is
   epsilon." 2. adj. very small, negligible; less than marginal. "we can
   get this feature for epsilon cost." 3. `within epsilon of': close enough
   to be indistinguishable for all practical purposes, even closer than
   being `within delta of'. "that's not what i asked for, but it's within
   epsilon of what i wanted." alternatively, it may mean not close enough,
   but very little is required to get it there: "my program is within
   epsilon of working."
