@cdonovick, can you confirm that the test_get_mant (in test_pe.py) is a valid test?

@rdaly It looks like you are defining bfloat incorrectly. It should be FPVector[8, 7, ...]. I'm also not sure how you are constructing from the fpdata tuple. I'm also not sure how it is being cast from FPVector to Bitvector. FGetMant looks correct to me.
Caveat I am trying to do this review on my phone while waiting in the security line at the airport so I might have missed something.
