import struct
pack it into a str [Python 2.X] using d format
unpack it using Q format, gets you a 64-bit unsigned int
do "some bit operation" using & | ^ ~ << >> operators
pack it into a str using Q format
unpack it into a float using d format

What is "some bit operation"? Perhaps there is already a high-level
way of doing some of what you want e.g. in the math module: frexp,
ldexp, isnan, isinf, ...
