Python 2 7 Floor Division

Also referred to as integer division.

Python 2 7 floor division.

In python 2 3 and later. Division and type conversion. 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. The resultant value is a whole integer though the result s type is not necessarily int.

But for floor division in python 2 int int int to understand m. 10 3 1 11 3 2 floor division. The dividend and the divisor. 2 3 first output is fine but the second one may be surprising if we are coming java c world.

There are two types of division operations in python. The division and floor division operators yield the quotient of their arguments. Floor division in python figure 1. The floor division operator is an example of a binary operator as it takes two operands.

Using to do division this way is deprecated. 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. The numeric arguments are first converted to a common type. In python the floor division operator consists of two forward slashes.

The result is that of mathematical division with the floor function applied to the result. Floor division the division of operands where the result is the quotient in which the digits after the decimal point are removed. In python 2 7 the operator works as a floor division for integer arguments. For python 2 x dividing two integers or longs uses integer division also known as floor division applying the floor function after division.

But if one of the operands is negative the result is floored i e rounded away from zero towards negative infinity 9 2 4 and 9 0 2 0 4 0 11 3 4 11 0 3 4 0. Plain or long integer division yields an integer of the same type. To get a float result in python 2 without floor rounding we can specify one of the operands with the decimal point. Floor division is also used to carry out euclidean division but unlike the modulo operator floor division yields the quotient not the remainder.

So for example 5 2 is 2. To give you another example 11 3 gives us a quotient of 3 and a remainder of 2. If you want floor division use available in python 2 2 and later. Ordinary division with operator 2.

However the operator returns a float value if one of the arguments is a float this is similar to c. With floor division one number the dividend is divided by another number.
