delta
1. A qua NTitative change, especially a small or increme NTal one (this use is general in physics and engineering). "I just doubled the speed of my program!" "What was the delta on program size?" "About 30 perce NT." (He doubled the speed of his program, but increased its size by only 30 perce NT.) 2. [Unix] A diff, especially a diff stored under the set of version-co NTrol tools called SCCS (Source Code Co NTrol System) or RCS (Revision Co NTrol System). See {change manageme NT}. 3. A small qua NTity, but not as small as epsilon. The jargon usage of delta and epsilon stems from the traditional use of these letters in mathematics for very small numerical qua NTities, particularly in "epsilon-delta" proofs in limit theory (as in the differe NTial calculus). The term delta is often used, once epsilon has been me NTioned, to mean a qua NTity that is slightly bigger than epsilon but still very small. "The cost isn' t epsilon, but it' s delta" means that the cost isn' t totally negligible, but it is nevertheless very small. Common constructions include "within delta of ---", "within epsilon of ---": that is, "close to" and "even closer to".
