[issue39436] Strange behavior of comparing int and float numbers

New submission from Petr Pisl : When python compares float and int created from the same int number should be equal like int(1) == float(1) but from 9007199254740993 this is not true. int(9007199254740993) == float(9007199254740993) is not true. The same behavior is for bigger odd
