>> What is the coolest way of programming the quadratic formula in J?
Here's a version (although not J) which I find rather cute: concise, perfectly accurate, easy to read, and if run through a computer, it prints in a most beautiful way that everybody recognizes at once ;) {-b \pm \sqrt{b^2-4ac} \over 2a} ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
