    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. This is 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."
