Under your proposal, `math.isnan(101000)` would be `False`, but `math.isnan(Fraction(101000))` would again raise an `OverflowError`, as would `math.isnan(Decimal('1e500'))`.

But what you're proposing doesn't match that description! Under your proposal, `math.isnan(10**1000)` would be `False`, but `math.isnan(Fraction(10**1000))` would again raise an `OverflowError`, as would `math.isnan(Decimal('1e500'))`.
