The rationale for a separate imaginary type has been laid out in Kahan & Thomas, "Augmenting a programming language with complex arithmetic", http://www.eecs.berkeley.edu/Pubs/TechRpts/1992/CSD-92-667.pdf, and has also been requested on the D mailing lists: http://forum.dlang.org/thread/[email protected] Briefly, it should allow more efficient calculations (as unnecessary manipulations of 0 are avoided) and should allow a way round some calculations that unnecessarily evaluate to NaN under the IEEE floating point standard.

IMHO, this is not a bug, but a request for an enhancement...
