A Survey of Error Analysis.

Abstract : Rounding error is just one kind of error, and an easier kind to analyze than some others. Error and uncertainty in data is a more important kind, and not so easy to estimate nor analyze; here is where error analysts are currently busiest. The most refractory kind of error is attributable to flaws in the design of computer systems, both hardware and software, caused primarily by misconceptions about the other kinds of error. (Author)
