floating point verification using is?

If I have 2 identical floating point values, how do I ensure they are  
binary equivalents of eachother?  I'm trying to write some unittest/assert  
code, and it's not exactly trivial.

I thought 'a is b' would work, but it just morphs into a == b, which isn't  
helpful.  Why doesn't 'is' just do a bit compare for floating points?
