This is right.

This is wrong, since there is a loss of information in the float cast:
>>> float('9007199254740993.0')
9007199254740992.0
Notice the last digit switched from a 3 to a 2? Floats in python don't
have arbitrary accuracy. You would need to import decimal and use it
for rounding to work properly.
