Benefits of Double Division Operator over Single Division Operator in Python
The Double Division operator in Python returns the floor value for both integer and floating-point arguments after division.
2 -3 2.0
The single division operator behaves abnormally generally for very large numbers. Consider the following example.
500000001.0 50000000000000000 50000000000000001
The Output should have been Hello if the single division operator behaved normally because 2 properly divides x. But the output is World because The results after Single Division Operator and Double Division Operator ARE NOT THE SAME.
This fact can be used for programs such as finding the sum of first n numbers for a large n.
Sum using single division operator : 50000000005000003584 Sum using double division operator : 50000000005000000000
Thus the result found by using the single division operator is Wrong, while the result found by using the double division operator is Correct. This is a huge benefit of Double Division Operator over Single Division Operator in Python.
