Answer:
You look at the operands of the operator.

But what if one operand is an integer and the other is a floating point? The rule is:

            


            
For example, the following are integer operations (assume that a and b are int variables):

            

                
                    

                        
                            
12 * b

                        		
                        
                            
a - 2

                        		
                        
                            
56%a

                        		
                    

                
            

            
Each operation in the following expressions is a floating point operation (assume that a and b are int variables, and that x and y are floating point
                variables):

        

    





    

        

            

                

            

        

    





    

        

            

                
                    

                        
                            
x * b

                        		
                        
                            
(a - 2.0)

                        		
                        
                            
56*y

                        		
                    

                
            

        

        

            
In complicated expressions, an operand of a particular operator might be a subexpression. But the rule still applies: if one or both operands is a floating point type then the operation is floating point. In the following, each / operation
                is floating point:

            

                
                    

                        
                            
(12.0 * 31) / 12

                        		
                        
                            
(a - 2.0) / b

                        		
                        
                            
56*x/3

                        		
                    

                
            

            
In that last example, the 56*x is a floating point subexpression that becomes an operand for the division operator. (Because * and / have equal precedence, the evaluation
                is done from left to right.)
