While it can not cause any loss of precision for numbers under
2**53, and all the affected cases do not deal with numbers larger than0xffffff, this is still a code smell (and is not obviously correct - usingint(value / 4)instead ofvalue // 4can cause loss of precision for e.g.value = 2**63 - 1, resulting in a number off by one. Using floordiv with Python integers (which do not have limited bitwidth) avoids such questions entirely.
