Rounding of a number is a process to assign a numerical value to place value. Rounding number calculator is a calculator
tool which round off the number up to specified digits.
To round off a number we look at the right digit of the place value and decide the numerical value of place value
accordingly. If it is less than 5 then place value remains unchanged. If it is 5 or greater than 5 then numerical value of
place value becomes one more than place value.
Example 1: round 25.2 to nearest tens.
Solution: here tens place digit is 2 and its place value is 2. Number to the right side of 2 is 5. Since it is 5 or greater than 5 we
increase a place value 2 by 1 and right side digit 5 becomes zero.
2 + 1 = 3 and instead of 5 write 0.
Hence 25.2 rounding to nearest tens is 30.
Example 2: round 1001.9 to the nearest thousands.
Solution: here thousands place digit is 1 and units place digit is 1. Since units place digit is 1
(i.e. less than 5) numerical value of thousands place number remains same as its place value.
Make all digits zero except the thousand place digit. Hence we get a number rounded to the nearest thousands of 00.9 as
