What Is Floor Division

To round a floating point number look at the round function.

What is floor division.

The behavior of this method follows ieee standard 754 section 4. If the passed argument is an integer the value will not be rounded. 2 5 would fit in the middle. This kind of rounding is sometimes called rounding toward negative infinity.

It basically cuts of the part after the period. For example 5 2 in floor division is not 2 5 but 2. Floor division description. Floor division is division where the answer is rounded down.

To round a number up to the nearest integer look at the ceil function. The floor function rounds a number down to the nearest integer if necessary and returns the result. But for floor division in python 2 int int int to understand m. Double values 7 03 7 64 0 12 0 12.

Floor division with operator note. Floor division means the will. Ordinary division with operator 2. Division works differently in python 2 and 3.

The following example illustrates the math floor double method and contrasts it with the ceiling double method. Division by a power of 2 is often written as a right shift not for optimization as might be assumed but because the floor of negative results is required. Remarks also referred to as integer division. The floor method rounds a number downwards to the nearest integer and returns the result.

If you imagine a room where 3 is on the ceiling and 2 is on the floor. 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. 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. Assuming such shifts are premature optimization and replacing them with division can break software.

The resultant value is a whole integer though the result s type is not necessarily int.
