:Well, they are similar, but I don't think they're the same thing. Round-off error inherently uses rounding, while quantization error can be rounding, truncation, etc. (Not sure what it is for floating-point numbers.) Also quantization error is generally found in discussions about sampling theory and the error between internal representation and real-life signals , while round-off error is generally about computations on numbers.
:In other words, in the signal processing realm, quantization error is added to a signal when it is first digitized, and round-off error is added as you do computations on that already-digital signal. Maybe they are the same thing with different names, but I think they are different enough to have different articles. Maybe, maybe not. — [[User:Omegatron|Omegatron]] 14:14, 18 October 2005 (UTC)
