Python 3 Floor Division

Division and type conversion.

Python 3 floor division.

The resultant value is a whole integer though the result s type is not necessarily int. Ordinary division with operator 2. Python operator examples. Using to do division this way is deprecated.

If you want floor division use available in python 2 2 and later. So for example 5 2 is 2. For python 2 x dividing two integers or longs uses integer division also known as floor division applying the floor function after division. Here are a few examples to illustrate the same.

The operators and work just like in most other languages for example pascal or c. Floor division with operator note. Expression syntax is straightforward. This means that a b first divides a by b and gets the integer quotient while discarding the remainder.

You can type an expression at it and it will write the value. 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. 10 3 3 3333333333333335 and in python 2 x. But for floor division in python 2 int int int to understand m.

In python 2 the quotient returned for the expression 11 2 is 5. 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. There are two types of division operations in python.

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. Python 3 s approach provides a fractional answer so that when you use to divide 11 by 2 the quotient of 5 5 will be returned. In python 2 7 the operator works as a floor division for integer arguments. Division works differently in python 2 and 3.

2 3 first output is fine but the second one may be surprising if we are coming java c world. Parentheses can be used for grouping. The interpreter acts as a simple calculator. 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.

This operation brings about different results for python 2 x like floor division and python 3 x. Python 2 s operator performs floor division where for the quotient x the number returned is the largest integer less than or equal to x.
