ROUND in Excel

The Microsoft Excel ROUND Function is a Math/Trig Function, which is used to return a number rounded to a specific number of digits. The ROUND in Excel can be used as a worksheet function in Excel worksheets. You can use this ROUND in Excel to round to the right or left of the decimal point.

ROUND Formula in Excel

The ROUND Formula in Excel accepts the following parameters and arguments:

Number – The number which has to be rounded.

Num_Digits – The total number of digits to round the number to.

Return Value:  The ROUND function in excel returns a numeric value.

ROUND in Excel Usage Notes

1. The ROUND function in Excel works by rounding the numbers 1-4 down and rounding the numbers 5-9 up.
2. You can use the ROUND function in excel for rounding numbers to a specified level of precision. ROUND can be used for rounding to the right or left of the decimal point.
3. If num_digits is greater than 0, number will be rounded to the specified decimal places to the right of the decimal point. For example, =ROUND (16.55, 1) will round 16.55 to 16.6.
4. If num_digits is less than 0, number will be rounded to the left of the decimal point (i.e. to the nearest 10, 100, 1000, and so on). For example, =ROUND (16.55, -1) will round 16.55 to the nearest 10 and return 20 as the return value or result.
5. If num_digits = 0, number will be rounded to the nearest integer (no decimal places). For example, =ROUND (16.55, 0) will round 16.55 to 17.

 

Explanation of ROUND Function in Excel in Terms of Math Rules

The ROUND in excel follows the general math rules for rounding the numbers. In this Excel Round Function, the number to the right of the rounding digit will determine whether the number should be rounded upwards or downwards. The rounding digit is considered to be the last significant digit after the number is rounded and it also gets changed which depends on whether the digit that is following it is less or greater than 5.

• In case the digit to the right of the rounding digit is 0,1,2,3, or 4, the rounding digit will not be changed, and the number will be rounded down.
• In case the rounding digit is followed by 5,6,7,8, or 9, the rounding digit will be increased by one and the number will be rounded up.

Consider the following table to understand the above theory more deeply. In this ROUND in Excel example, we are taking the Number 106.864 and the position is cell number A2 in the spreadsheet.

Formula	Result	Description
=ROUND (A2,2)	106.86	Number in A2 is rounded to 2 decimal places.
=ROUND (A2,1)	106.9	Number is A2 is rounded to 1 decimal place.
=ROUND (A2,0)	107	Number in A2 is rounded to the nearest integer.
=ROUND (A2,-1)	110	Number in A2 is rounded to the nearest multiple of 10.
=ROUND (A2-2)	100	Number in A2 is rounded to the nearest multiple of 100.

How to Open the ROUND Function in Excel?

1. You can simply enter the desired ROUND formula in the required cell to attain a return value on the argument.
2. You can manually open the ROUND formula in Excel dialogue box in the spreadsheet and enter the logical values to attain a return value.
3. From the below spreadsheet, you can see the Formulas Section in the Menu Bar. Under the Formulas Section, Click on the Math & Trig.

4. After clicking the Math & Trig option, select ROUND. The ROUND formula in Excel dialogue box will open as shown below.

5. Now you can easily put the arguments and attain a return value. Just put the required values on Number and Num_digits and you will get the return value.

Other Rounding Functions in Excel

You can also force Excel to always round a number up (away from zero) with the help of ROUNDUP function in excel. If you want to force Excel to always round a number down (towards zero), use the ROUNDDOWN function in Excel. For specifying the multiple (example 0.5) that Excel is using to round, use the MROUND function.
