Example 1: How round() works in Python? # for integers print(round(10)) # for floating point print(round(10.7)) # even choice print(round(5.5)) Run Code Output 10 11 6 Here, round(10):rounds the integer to10 round(10.7):rounds the float10.7to nearest integer,11. round(5.5):round...
A round-to-nearest operation takes an original number with an implicit or specified precision; examines the next digit, which is at that precision plus one; and returns the nearest number with the same precision as the original number. For positive numbers, if the next digit is from 0 throug...

Q4. In Python, the round() function rounds up or down? The round() function can round the values up and down both depending on the situation. For <0.5, it rounds down, and for >0.5, it rounds up. For =0.5, the round() function rounds the number off to the nearest even number....
Python uses the math module, NumPy, and Pandas libraries to offer different methods of rounding up numbers. Round up using the math module The math.ceil() function from math is used to round up a number to the nearest integer. The syntax is shown below. # Import the math module to acce...
