Cancellation[edit]

I saw your edit on loss of significance, where you say that it is also known as "cancellation". I'm sure you're right, but at the moment I can't think of an example. Could you please help my memory by giving an example where "cancellation" is used in that sense? Thanks. -- Jitse Niesen (talk) 03:31, 14 March 2007 (UTC)[reply]

Come to think of it I guess I'm not entirely sure that the concepts are equivalent, but there is a link in the Addition section of the floating point article called "cancellation" that links to Loss of significance. The terms are also used seemingly interchangeably in a lot of the text books I've read on numerical analysis (it is also sometimes referred to as "catastrophic cancellation"). Feel free to change it back if they are not the same! -- Ehdr 17:05, 14 March 2007 (UTC)[reply]
