When to use os.name, sys.platform, or platform.system?

....49999999999999994, (see it live).
Another common implementation involves casting a floating point type to an integral type, which can invoke undefined behavior in the case where the integral part can not be represented in the destination type. We can see this from the draft C++ standard section 4....
