This has been discussed quite a bit lately. Just as there are fractions 
for which no exact decimal representation exists (1/3, for example), 
there are decimal floating-point numbers for which no exact binary 
representation exists.

In an earlier thread on this topic, Chris Hulan said "Have a look at 
"What Every Computer Scientist Should Know About Floating-Point 
Arithmetic" (http://docs.sun.com/source/806-3568/ncg_goldberg.html)"
