Solution(By Examveda Team)
The correct answer is Option A: Rounds a floating-point number to the nearest integer.The round() function in Python is used to round a floating-point number to the nearest integer.
It takes one or two arguments. If given one argument, it rounds the number to the nearest integer.
If given two arguments, it rounds the first argument to the number of decimal places specified by the second argument.
For example:
num1 = 3.7
num2 = 9.2
rounded_num1 = round(num1)
rounded_num2 = round(num2)
print(rounded_num1) # Output: 4
print(rounded_num2) # Output: 9
