First, I didn't realize someone had already posted the way to do it with adding and subtracting before I posted it. But it only took two minutes to figure out (well, less, because that includes the time it took to write the message). So, sory for the repeative post. :) Second, someone said that the xor method doesn't work with negative numbers. That is false. It works just fine, with gcc 2.7.2 on Linux Slackware: Method One (xor) ---------------- A B -1 -3 2 -3 2 -1 -3 -1 Method Two (add) ---------------- A B -1 -3 -4 -3 -4 -1 -3 -1 Tested, too, with a = 1 and b = 9, and vice-versa (just in case). Anyway, it is kind of a tired topic. ObCircle: Completely hypothetical situation...if, someone--let's call him...Bob--was thinking about releasing a derivitive of Circle based on one of the bpls, that added/removed/changed features. What are some of the features that you think should be added to stock; removed from stock; and changed in stock. Your thoughts, please. (even my ObCircle wasn't all that much on topic :P) Hypothetically speaking, of course. daniel koepke / dkoepke@california.com +------------------------------------------------------------+ | Ensure that you have read the CircleMUD Mailing List FAQ: | | http://democracy.queensu.ca/~fletcher/Circle/list-faq.html | +------------------------------------------------------------+
