Dear all,

A few months ago I proposed to add an imaginary number class to boost in 
order to extend the std::complex class and improve performance when 
computations involving pure imaginary numbers are involved.  Some of you 
showed some interest and proposed some possible improvements, the main 
one being to actually replace the std::complex class by a boost::complex 
and boost::imaginary pair of classes in order for all operations to be 
truly symmetric and closer to the mathematical notation.

I have applied these modifications and the code now corresponds to an 
extended version of Thorsten Ottosen's n1869 proposal 
(http://www.open-std.org/JTC1/SC22/WG21/docs/papers/2005/n1869.html)

The sources and documentation are available here : 
http://code.google.com/p/cpp-imaginary-numbers/
They can be retrieved via the SVN repository or downloaded directly as 
an archive.

The archive contains the complex.hpp header, a performance test, an 
accuracy test and two examples showing the benefits of the imaginary 
numbers in "downscaled" real life situations. I have tentatively 
embedded everything in the boost::math namespace in order to look for 
potential naming conflicts between my code and the existing boost ones.

I would be happy to hear any comment from your side and still hope that 
this work is of some interest to you.

Regards,

Matthieu
