Hi all, A colleague of mine here at GW, who teaches both Ada and C++ here and is reasonably language-neutral, has asked me to probe my friends in net-land and find out "whether there are Ada projects out there that have really relied on complex numbers". Intuitively both of us think there are. He is a mathematician at heart, and a big believer that a language without complex support is doomed to fail in the scientific community. He wants, I think, to be able to "sell" complex numbers to students based on their genuine applicability and application. So please help me out if you can. Please don;t speculate - if you _know_ of a project that has used either an Ada 83 add-on, or the Ada 95 complex stuff, plase let me know privately. Tell me as much or as little as you feel comfortable with. Let's not start a thread here; I will summarize the responses after I get some.:-) Thanks! Mike Feldman
