Bug report

Bug description:

When using the ** operator with a Fraction as a base and an object that implements __rpow__ as an exponent the fraction gets wrongfully casted into a float before being passed to __rpow__

from fractions import Fraction

foo = Fraction(4, 3)

class One:
    def __rpow__(self, other):
        return other

bar = foo**One()
print(bar)
print(type(bar))

Expected Output

4/3
<class 'fractions.Fraction'>

Actual Output:

1.3333333333333333
<class 'float'>
