Equivalent to dataframe + other, but with support to substitute a fill_value for missing data in one of the inputs.

Parameters:

Parameters:	other : Series, DataFrame, or constant axis : {0, 1, ?index?, ?columns?} For Series input, axis to match Series index on fill_value : None or float value, default None Fill missing (NaN) values with this value. If both DataFrame locations are missing, the result will be missing level : int or name Broadcast across a level, matching Index values on the passed MultiIndex level
Returns:	result : DataFrame

axis : {0, 1, ?index?, ?columns?}
