A&S is Abramowitz and Stegun, a mathematical reference. It is a collection of common/useful mathematical formulae, and 26.2.16 is one of those formulae. You may find it spelled out here: http://www.math.ucla.edu/~cbm/aands//page_932.htm BTW, I am not a mathematician, so I don't know how familiar the work is in that community, but it certainly gets a lot of citations in the J Forum and the APL community generally (and Ken and Roger's posts/papers in particular, in my experience). -Dan Sent from my Verizon Wireless BlackBerry ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
