Summary: float issue for NaN type in .pyc file

Initial Comment:
There is a difference in output between .pyc and .py 
file, while dealing with NaN float. In fact I am doing 
a float range validation as part of my requirement. 

The content of my sample program
[test.py]
aboveMax = 1.8e+308
belowMin = -1.8e+308
print aboveMax, belowMin

While execution:
command: python test.py
output: 1.#INF -1.#INF
This output is expected and good, however if I use 
compiled python file as below,

command: python test.pyc
output: 1.0 -1.0 
This output is wrong, it does not show Nan floating 
point.
