We have
{{{
sage: ComplexIntervalField(64).an_element() +
RealIntervalField(128).an_element()
1 + 1*I
sage: parent(_)
Complex Interval Field with 64 bits of precision
}}}
But
{{{
sage: ComplexIntervalField(128).an_element() +
RealIntervalField(64).an_element()
Traceback (most recent call last):
...
TypeError: unsupported operand parent(s) for '+'
}}}
The above should work with parent `ComplexIntervalField(64)`.
