   @sandeep-krishnamurthy  This is a case of type promotion. Why is it an issue? In general in python, or in computer science, a warning or error is required only when there is a loss of information during a data type conversion. 
   
   If a float gets converted to an int then it is a matter of concern, but an int getting converted to a float should not be an issue, because there is no loss of information.
   
   For example, in the below code there is an implicit type promotion for the integer value ``a`` during the addition operation and we don't see any errors or warnings -
   ```python
   a = 1      # int value
   b = 1.5  # float value
   c = a + b
   print(type(c_sum))
   <class 'float'>
   ```
