What Is Floor Division In Python 3

Floor division always rounds away from zero for negative numbers so 3 5 will round to 4 but towards zero for positive numbers so 3 5 will round to 3.

What is floor division in python 3.

Let me use this math floor function of python on list items. Division and type conversion. Html css python javascript java sql bash shell ruby c r c php go swift kotlin. Ordinary division with operator 2.

There are two types of division operations in python. This means that a b first divides a by b and gets the integer quotient while discarding the remainder. Python floor division example a 10 b 3 x a b print x y a b print y output. For python 2 x dividing two integers or longs uses integer division also known as floor division applying the floor function after division.

However the operator returns a float value if one of the arguments is a float this is similar to c. The fractional part is truncated if there. This means that the result of a b is always an integer. Floor division with operator note.

If you imagine a room where 3 is on the ceiling and 2 is on the floor. Here we are using the for loop to iterate list item and then applying floor function for each item. This operation brings about different results for python 2 x like floor division and python 3 x. Floor division means the will always take the floor or the lower number.

Python floor list example. Division works differently in python 2 and 3. 10 3 3 truncation division also known as floordivision or floor division the result of this division is the integral part of the result i e. In python 2 7 the operator works as a floor division for integer arguments.

Also referred to as integer division. Using to do division this way is deprecated. The resultant value is a whole integer though the result s type is not necessarily int. 10 3 3 3333333333333335 and in python 2 x.

If you want floor division use available in python 2 2 and later. But for floor division in python 2 int int int to understand m. The operator in python 3 is used to perform floor based division. Here are a few examples to illustrate the same.

2 3 first output is fine but the second one may be surprising if we are coming java c world. 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.
