Scheme seems to think so.E.g.: (magnitude 2+3i) => 3.605551275463989 (magnitude +2i) => 2 This is just the distance to the origin (0,0) in 2space. It is very well defined. Without complex _numbers_ you can't do a lot of math (e.g. in electronics). Is the point 2+3i more real to you than +2i? Are 2d points less real than "points on the number line"? I think you made my point. 8^) In 3space you can do even more! ;^) -KenD _______________________________________________ r6rs-discuss mailing list r6rs-discuss@lists.r6rs.org http://lists.r6rs.org/cgi-bin/mailman/listinfo/r6rs-discuss
