> What are the use-cases for float // float where integer result is not acceptable?
It can lead to unexpected memory consumption when dealing with
arbitrary precision values. What should Decimal('1e123456')//1 return?
The result is exactly equal to Decimal('1e123456') but the
corresponding Python integer will consume ~55KB of RAM.
I'm also concerned that returning a very large integer will lead users
to assume that the result is more precise than it really is. Assuming
standard 64-bit double format, only the first 53 bits are significant.
All the remaining bits are 0.
