The fix broke NumPy (see also https://github.com/numpy/numpy/pull/19612)
It seems incorrect. After all, it doesn't matter much whether the float can be converted to an integer correctly (or even if it returns an undefined value), so long `int_value == float_value` remains sensible.
The old cast cast integers to complex when they were out of range (which is fine), the new code raises an error instead.
