Let's round down the given number n to the nearest integer which ends with 0 and store this value in a variable a. a = (n / 10) * 10. So, the round up n (call it b) is b = a + 10. If n - a > b - n then the answer is b otherwise the answer is a.

To round off any number to any decimal place we can use this method by first multiplying the input number with 10 ^ decimal place, so in our case it is 2 that is Math.round(3.14159265359 * (10 ^ 2)) and then divide it by 10 ^ decimal place like Math.round(3.14159265359 * (10 ^ 2)) / (10 ^ 2) so it will now round off the given number to 2 decimal places. If (Num%10)> 0){ Num = Num + ( 10 - (Num%10)) } Basically take 10 - mod of the number and add it to the number

For example, if we want to round 9,842 to the nearest 10, we'd divide it by 10 to get a decimal: 984.2. Then, we can use Math.round () on that number, and multiply the result by our precision again to return it to it's correct value/length.
