How To Do Floor Division In Python

I hope you learnt something new and if you re looking to upgrade your python skills even further you might want to check out our complete python course.

How to do floor division in python.

If you want floor division use available in python 2 2 and later. For python 2 x dividing two integers or longs uses integer division also known as floor division applying the floor function after division. Python number method floor returns floor of x the largest integer not greater than x. Floor division and modulo are linked by the following identity x x y y x y which is why modulo also yields unexpected results for negative numbers not just floor division.

Let us again consider the python equation. So for example 5 2 is 2. Division and type conversion. First output is fine but the second one may be surprising if we are coming java c world.

The floor division operator will always return an integer value if the 2 operands that it takes be integers. Integer division and float division. However the operator returns a float value if one of the arguments is a float this is similar to c. In python 2 7 the operator works as a floor division for integer arguments.

That is the values after the decimal point are discarded. Integer division returns the floor of the division. But for floor division in python 2 int int int to understand m. 8 5 1 6 but let us do things a little differently.

Using to do division this way is deprecated. The resultant value is a whole integer though the result s type is not necessarily int. Division works differently in python 2 and 3. It is written as in python 3.

In python there are two kinds of division. X this is a numeric expression. Floor division with operator note. There are two types of division operations in python.

If you imagine a room where 3 is on the ceiling and 2 is on the floor. 8 5 1 in the above example we have now employed the floor division operator. Integer values are precisely stored so they are safe to use in. Import math math floor x note this function is not accessible directly so we need to import math module and then we need to call this function using math static object.

So 1 3 0 2 3 0 and 3 3 1. 2 5 would fit in the middle. Following is the syntax for floor method.
