If you are one of those persons who work with statistical data or analyze data a lot, then this formula might be useful for you in so many ways. Here we will learn to round a number to the nearest 1000, 100, and 10.

## Round a Number to the Nearest 1000

In Excel, there’s a function called ROUND that you can use to round a number to the nearest 1000. Here I have the number “123456789”, and I want to round this number.

You can use the following steps.

- First, edit cell B1, and start entering the ROUND function “=ROUND(”.
- Now, refer to cell A1 where we have the number that you want to round.
- Next, in the second argument, enter -3.
- In the end, enter the closing parenthesis and hit enter to get the result.

=ROUND(A1,-3)

The moment you hit enter it returns 123457000 which the rounded to 1000 version of 123456789. As you have the last four numbers 6789, it has rounded it to 7000.

But if you change that number to 123456489 where you have 6489 in the end, the same function rounds it downwards to 123456000.

The ROUND function is quite smart to identify on which side the number needs to be rounded. But there might be a situation where you need to ROUND down or up a number to the nearest 1000.

=ROUNDDOWN(123456789,-3) = 123456000

=ROUNDUP(123456489,-3) = 123457000

## Other Methods to Round a Number to the Nearest 1000

There are a few more ways that you can use it:

**FLOOR Function**: FLOOR(123456789,1000) = 123457000- In this function, you need to use a positive 1000 to round a positive number and a negative -1000 to round a negative number.

**CEILING Function**: CEILING(C1,1000) = 123457000- In this function, you need to use a positive 1000 to round a positive number and a negative -1000 to round a negative number.

## ROUND a Number to Nearest 100

In the same way, you can use the ROUND function to round a number to the nearest 100. For this, you just need to use the -2 in the num_digit argument.

=ROUND(A1,-2)

## ROUND a Number to Nearest 10

And if you want to round a number to the nearest 10, then you use the ROUND function in the following way.

=ROUND(A1,-1)
