How to Use the Rounding Function in Excel Simply and Effectively

Learning how to use the rounding function in excel simply and effectively doesn't have to be complicated. This updated guide presents a clear workflow, practical checks, and troubleshooting advice you can use while completing the process.

Key Takeaways

• Review ROUND() function - rounds numbers after and before decimal points.
• Explore MROUND() function - rounds to a multiple of another number.
• Understand ROUNDDOWN() and ROUNDUP() functions.

1. ROUND() Function - Rounds Numbers After and Before Decimal Points

Syntax:

ROUND(Number to round, num_digits).

In there

Example:

With the number 1234.5678, when you use the Round function, the result will be as shown below:

2. MROUND() Function - Rounds to a Multiple of Another Number

Syntax:

MROUND(number to round, multiple).

- Multiple: The number you need to round the number to its multiple.

- If Number and Multiple have different signs, the function will report the #NUM! Error.

- If Number and Multiple are equal, the result is the number itself.

- MROUND() will round up, if the divisor of Number by Multiple is greater than or equal to 1/2 Multiple, and round down if the divisor of Number by Multiple is less than 1/2 Multiple.

Example:

Suppose you need to round to a multiple of another number, the result of rounding will be as illustrated below:

3. ROUNDDOWN() and ROUNDUP() Functions

These two functions are essentially the same as the ROUND() function, except that they only round in one direction: ROUNDDO?() always rounds a number toward 0, while ROUNDUP() always rounds a number away from 0.

Syntax:

ROUNDDOWN(Number to round, num_digits).

ROUNDUP(number, num_digits)

Example:

You can see the comparison result between ROUNDDOWN() and ROUNDUP() functions in the Excel table below:

4. CEILING() Function and FLOOR() Function

These two functions are similar to the MROUND() function - rounding to the nearest multiple of a specified number, with a slight difference in the calculation method: CEILING() always rounds a number away from 0, while FLOOR() rounds towards 0.

Syntax:

CEILING(Number to be rounded, significance).

FLOOR(number, significance)

- Significance: The number to which you need to round the Number to a multiple of it.

- If Number and Significance have different signs, the function will report the #NUM! Error.

- If Number is a multiple of Significance -> the result is that number.

Example:

Suppose we need to compare between CEILING(), FLOOR() and MROUND() - in this example, consider Significance as Multiple of MROUND() -> you will get the result as shown below:

5. EVEN() and ODD() Functions

These two functions round very simply. EVEN() rounds to the nearest even integer, and ODD() rounds to the nearest odd integer. Both round away from zero.

Syntax:

EVEN(number)

ODD(number)

Example:

Suppose you need to round numbers in Excel and use 2 functions EVEN and ODD, you get the result as illustrated below:

6. INT() and TRUNC() Functions

These two functions are almost the same in usage if you want to round a number to an integer.

Syntax:

INT(number)

TRUNC(number [, num_digits])

- Num_digits: Is an integer, indicating how you want to truncate the number.

- Num_digits > 0 if Number is a decimal number, then Num_digits indicates the number of decimal places you want to keep (after the decimal point).

- Num_digits = 0 or not entered: remove all decimal parts of Number (if any).

- Num_digits less than rounds Number to an integer and rounds Number left to a multiple of 10.

The INT() function rounds a number to the nearest integer.

For positive numbers, INT() and TRUNC() give the same result ( Num_digits of TRUNC() = 0 or none), but for negative numbers, the two functions give completely different results.

Example:

INT(123,456) = 123 | TRUNC(123,456) = 123.

INT(-123.456) = -124 | TRUNC(-123.456) = -123.

TRUNC() is different from ROUND() in that: ROUND() rounds, while TRUNC() only truncates the number but doesn't round when Num_digits is not 0.

Some examples of the TRUNC() function to help you visualize:

This guide has just introduced you to how to use rounding functions in Excel, including: ROUND, ROUNDUP, ROUNDDOWN, MROUND, CEILING, FLOOR, EVEN, ODD, INT and TRUNC.

Understanding the rounding functions makes it easier to calculate more accurately and conveniently when working with Excel. In addition, you should also learn the basic functions in Excel to improve work efficiency and process data effectively.

Final Thoughts

The most reliable way to handle use the rounding function in excel simply and effectively is to follow the process in order, verify each important setting, and test the result before moving on. Use the guidance above as a practical reference, then adjust the details for your device, software version, or specific goal.
