2.Why does round(5 / 2) return 2 instead of 3? (BRAIN) >>> round(7 / 2) >>> round(3 / 2) >>> round(5 / 2)

Best answer

**Answer 1: ***4, 2, 2*

**Answer 2:***The issue here is that Python’s round method implements banker’s rounding, where all half values will be rounded to the closest even number.*

the answer is 2.5 so if its returning an integer, it will disregard everything after the decimal point

the round() function rounds the quotients of 7/2 and 3/2 to the nearest integer, which is 3 and 1, respectively. However, the quotient of 5/2 is rounded to 2. This is because the quotient 2.5 is closer to 2 than it is to 3.

the round() function performs rounding based on certain rules. In the case of half-values (e.g., 2.5), it rounds to the nearest even number. This behavior is known as "round half to even" or "rounding to nearest, ties to even."

because integer / integer is always be a integer

like 5/2 is integer /integer then answer is integer it remove the number after the point and showing only who's number are before point

The result of the execution of the following code is:

2

3

2

The round() function rounds a number to the nearest integer. In the first two cases, the result is the nearest integer to the quotient of the two numbers. In the third case, the quotient, 2.5, is halfway between 2 and 3. The round() function rounds halfway cases to the even number, so the result is 2.

The round() function uses a rounding algorithm called banker's rounding. Banker's rounding is a rounding algorithm that rounds halfway cases to the even number. This algorithm is often used in financial applications because it is considered to be more fair than other rounding algorithms.

rounding option rounds to the next higer integer value if the number of digits for precision is zero. hence 5/2 is only 3. not 2
