 # ROUND

In this comprehensive guide, we will explore the ROUND function in Excel, which is a widely used formula for rounding numbers to a specified number of digits. This article will cover everything you need to know about the ROUND function, including its syntax, examples, tips and tricks, common mistakes, troubleshooting, and related formulae. By the end of this guide, you will have a thorough understanding of the ROUND function and how to use it effectively in your Excel spreadsheets.

## ROUND Syntax

The ROUND function in Excel has a simple syntax with two required arguments:

=ROUND(number, num_digits)

number – This is the number you want to round. It can be a cell reference, a formula, or a constant value.

num_digits – This is the number of digits to which you want to round the number. A positive value will round to the right of the decimal point, a negative value will round to the left of the decimal point, and a value of 0 will round to the nearest integer.

## ROUND Examples

Here are some examples to help you understand how to use the ROUND function in Excel:

Example 1: Basic rounding

=ROUND(3.14159, 2)

This formula will round the number 3.14159 to two decimal places, resulting in 3.14.

Example 2: Rounding with a cell reference

=ROUND(A1, 1)

Assuming cell A1 contains the value 5.678, this formula will round the value in A1 to one decimal place, resulting in 5.7.

Example 3: Rounding with a negative num_digits value

=ROUND(12345, -2)

This formula will round the number 12345 to the nearest hundred, resulting in 12300.

Example 4: Rounding the result of a calculation

=ROUND(SUM(A1:A10) / 10, 2)

This formula will calculate the average of the values in cells A1 to A10 and round the result to two decimal places.

## ROUND Tips & Tricks

Here are some tips and tricks to help you get the most out of the ROUND function in Excel:

1. Use the ROUND function in combination with other functions, such as SUM, AVERAGE, or COUNT, to round the results of calculations.
2. If you want to round a number to the nearest integer, you can set the num_digits argument to 0.
3. To round a number to the nearest multiple of a specific value, you can use the MROUND function.
4. Remember that the ROUND function uses “round half to even” or “bankers’ rounding” method, which means that if the number to be rounded is exactly halfway between two possible rounded values, the function will round to the nearest even number.

## Common Mistakes When Using ROUND

Here are some common mistakes that users make when using the ROUND function in Excel:

1. Forgetting to include both the number and num_digits arguments in the formula.
2. Using a positive num_digits value when you want to round to the left of the decimal point, or a negative value when you want to round to the right of the decimal point.
3. Not understanding the “round half to even” method used by the ROUND function, which can lead to unexpected results in some cases.

## Why Isn’t My ROUND Function Working?

If your ROUND function isn’t working as expected, here are some possible reasons and solutions:

1. Check that you have included both the number and num_digits arguments in the formula.
2. Ensure that the num_digits argument has the correct sign (positive, negative, or 0) for the desired rounding direction.
3. Make sure that the number argument is a valid number, cell reference, or formula.
4. If you’re still having trouble, consider using alternative rounding functions, such as ROUNDDOWN, ROUNDUP, or MROUND, depending on your specific needs.

## ROUND: Related Formulae

Here are some related formulae that you might find useful when working with the ROUND function in Excel:

1. ROUNDDOWN: This function rounds a number down to a specified number of digits. Syntax: =ROUNDDOWN(number, num_digits)
2. ROUNDUP: This function rounds a number up to a specified number of digits. Syntax: =ROUNDUP(number, num_digits)
3. MROUND: This function rounds a number to the nearest multiple of a specified value. Syntax: =MROUND(number, multiple)
4. FLOOR: This function rounds a number down to the nearest multiple of a specified value. Syntax: =FLOOR(number, significance)
5. CEILING: This function rounds a number up to the nearest multiple of a specified value. Syntax: =CEILING(number, significance)

By mastering the ROUND function and its related formulae, you can greatly enhance your ability to manipulate and analyze numerical data in Excel. We hope this comprehensive guide has provided you with all the information you need to use the ROUND function effectively in your spreadsheets.
