Madcoder, old boy, perhaps you have not paid enough attention to what I have
been saying.  From your own comments here, I doubt you are qualified to judge
whether or not my understanding of IEEE representation is sufficient.

It seems that you yourself don't understand the right to freedom of speech. 
Feel free to disagree with me, even vehemently- but you can't stop me from
saying what I want to.

I am well aware of the IEEE rounding modes etc.  I am equally aware of the rules
of decimal arithmetic.

When a standard library cannot convert a value with max precision 15 decimals
from text to a double precision and back to the same text then I couldn't give a
hoot about IEEE rounding modes- your binary to text conversion is broken.

Your head is so deeply buried in the pile of standards documents that you can't
see reason.  Standards are like statistics.  You can get them to say just about
anything you like.

Refer to the program listing above for a binary to decimal conversion procedure
that actually works.
