[edit] arbitrary precision?
I don't believe that lanczos can be used for arbitrary precision because it is a single asymptotic expansion and is thus subject to divergence due to stoke's phenomenon. Does anyone have evidence that it is suitable for arbitrary precision? --njh 04:34, 13 June 2006 (UTC)
