How to round off a two decimal number to the nearest number?

Question

67.12
=67
And. 52.51
=53 and not 52

Answer 1

double a = 45.67;
System.out.println((int)Math.round(a));

Answer 2

import the math class to your project using the next line of code.

import java.lang.Math;

You can then round variable type double like you describe. the next line is an example where x holds the value you want to round.

System.out.println(Math.round(x));

Answer 3

It’s been a while every since I did rounding back in my days but I’ll try to help you:
Round the number n to p decimal places by first shifting the decimal point in n by p places by multiplying n by 10ᵖ (10 raised to the p th power) to get a new number m . Then look at the digit d in the first decimal place of m . If d is less than 5, round m down to the nearest integer. Otherwise, round m up.
Just like Real life, check the number on your right (I mean the digits) if that digit on the right is 5 or higher then round it to the nearest 10s.
Example: 38 rounded to the nearest ten is 40.
Hope this helps 👌😄
