Details:

The target user for most of Octave is scientists and engineers.  The
scientists can already display results in their favorite format,
scientific notation.  Engineers, however, have to make due with
scientific notation.  As an electrical engineer I do a lot of work with
kiloOhms and megaOhms and it would be much more convenient if I could
display results in an engineering format (mantissa + exponent where the
exponent is a multiple of 3). 

I realize the C++ stream libraries don't naturally support engineering
format, but a look at the code in pr-output.cc seems like it should be
possible to insert a routine that does the work before passing it on to
the output.  Not that it matters, but Matlab has figured it out and
'format eng' is an accepted command
(http://www.mathworks.com/access/helpdesk/help/techdoc/ref/format.html).
