testing equality of floating point - any libraries?

About two years ago, I saw an article in some C++/programming
journal (whose name I have forgotten) about testing equality 
of floating point numbers.  The author had used templates,
gave a thorough discussion of the all the issues, and
his solution with source code.  Unfortunately I was never
able to find it when I came to look for it, and all I remember
is that the author had a maybe Indian name.  

Can anyone guide me to the original article, or a good 
C++ implementation for this task?  I didn't notice
anything relevant on the Boost libraries page.

Thanks,
Paul.

p.s. I know about the C solution at http://fcmp.sourceforge.net/.
