But for floor division in python 2 int int int to understand m.
Python floor division negative numbers.

Ordinary division with operator 2.
Python s default division of integers is return the floor towards negative infinity with no ability to change that.
The rounding towards zero behavior was deprecated in python 2 2 but remains in python 2 7 for the sake of backward compatibility and was removed in python 3.
5 2 2 but if one of the operands is negative the result is floored i e rounded away from zero towards negative infinity.
In python 2 the quotient returned for the expression 11 2 is 5.
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.
To do round up division you would use.
The truncate towards negative infinity rule can cause precision loss for x 1 0 when x is a very small negative number.
To get a float result in python 2 without floor rounding we can specify one of the operands with the decimal point.
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.
You can read the bdfl s reason why.
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.
I was asked again today to explain why integer division in python returns the floor of the result instead of truncating towards zero like c.
7 2 3 but python is giving output 4.
Phyton python floor division operator python floor division example python floor the expression 6 4 yields 1 where floor division produces the whole number after dividing a number.
There are two types of division operations in python.
Division works differently in python 2 and 3.
But with a negative number why does 6 4 return 2.
Tim peters who knows where all python s floating point skeletons are buried has expressed some worry about my desire to extend these rules to floating point modulo.
The above example of 2 3 which gives 0 in python 2 shall be used as 2 3 0 or 2 0 3 or 2 0 3 0 to get 0.
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.
For positive numbers there s no surprise.
