Hi,
I pushed a new change with short support to my branch here.
http://bitbucket.org/rpg/eigen2-rpg-branch/overview/
I did just as Benoit spelled out here,
http://listengine.tuxfamily.org/lists.tuxfamily.org/eigen/2009/08/msg00108.html
If you look into the NumTraits.h and MathFunctions.h files, the short
portion added by me is a virtual clone of the int portion. with int
replaced by float.
Yet, when I try to run the unit tests, I get this,
~/Documents/numerical/eigen2-rpg-branch/build@rpg> make -j2

Will somebody be please kind enough to look into what went wrong?
precision<short> is plainly there. Thanks
