ROUND Function
ROUND Function in Excel
Summary
The Excel ROUND function returns a number rounded to a given number of digits. The
ROUND function can round to the right or left of the decimal point.
Purpose
Round a number to a given number of digits Return value A
rounded number.
Syntax
=ROUND (number, num_digits) Here, =ROUND (A2, B2) // Result
is in C2
The formula is
The result is
Arguments
• number - The number to round.
• num_digits - The number of digits to which number should
be rounded.
Usage notes
• The
ROUND function rounds a number to a given number of places. The number of
places to
round to is controlled by the number of digits provided to ROUND, as
seen in the table below:
Example 1 - round to right
To round values to the right of the decimal point, use a positive number for digits:
=ROUND(A1,1) // Round to 1 decimal place
=ROUND(A2,2) // Round to 2 decimal places
=ROUND(A2,3) // Round to 3 decimal places
=ROUND(A2,4) // Round to 4 decimal places
Example 2 - round to left
To round values to the left of the decimal point, use
zero or a negative number for digits:
=ROUND(A2,0) // Round to nearest whole number
=ROUND(A2,-1) // Round to nearest 10
=ROUND (A2,-2) // Round to nearest 100
=ROUND (A2,-3) // Round to nearest 1000
=ROUND (A2,-4) // Round to nearest 10000
Example 3 - nesting inside ROUND
Other operations and functions can be nested inside the ROUND function. For example, to
round down the result of A1 divided by B1, you can ROUND in a formula like this:
=ROUND(A2/B2,0) // round result to nearest
integer
Any formula that returns a numeric result can be nested inside the ROUND function.
Notes
• Round works by rounding numbers 1-4 down and rounding
numbers 5-9 up.
• The ROUND function rounds numbers to a specified level of precision, determined by
num_digits.
• If a number is already rounded to the given number of places, no rounding occurs.
Round to nearest 1000
Formula
=ROUND(number,-3)
Explanation
If you need to round a number to the nearest 1000, you can use the ROUND function and
supply -3 for number of digits.
How this formula works
In the example, cell C2 contains this formula: =ROUND(A2,-3)
The result will be
The value in A2 is 45955.784 and the result is 46000. With the ROUND function, negative
numbers for the second argument round to the left of the decimal and positive numbers
round to the right of the decimal. In this case, by supplying -3, we are telling ROUND to
round the number to the 3rd
place on the left – the 1000's place.
