It actually is possible to represent 0.1 exactly in binary, but not in IEEE Floating Point. Check out unum by John Gustafson.

You are absolutely correct; there are multiple varieties of floating points available out there. I should have specified IEEE-754 definitions since those are the ubiquitous (but not sole) representations of floating points in modern computing. Thanks for the clarification!
