The round() function is used to round a number to the nearest integer. Let's calculate the results:

round(3 / 2) is equal to round(1.5), and when rounded to the nearest integer, it becomes 2.

round(5 / 2) is equal to round(2.5), and when rounded to the nearest integer, it becomes 2.

So, the results are:

round(3 / 2) equals 2.

round(5 / 2) equals 2.

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