MS Access: Round Function

This MSAccess tutorial explains how to use the Access Round function with syntax and examples.


The Microsoft Access Round function returns a number rounded to a specified number of decimal places. However, the Round function behaves a little peculiar, so before using this function, please read the following:

The Round function utilizes round-to-even logic. If the expression that you are rounding ends with a 5, the Round function will round the expression so that the last digit is an even number.

For example:

Round (12.55, 1)
Result: 12.6   (rounds up)

Round (12.65, 1)
Result: 12.6   (rounds down)

Round (12.75, 1)
Result: 12.8   (rounds up)

In these cases, the last digit after rounding is always an even number. So, be sure to only use the Round function if this is your desired result.


The syntax for the Round function in MS Access is:

Round ( expression, [ decimal_places ] )

Parameters or Arguments

expression is a numeric expression that is to be rounded.

decimal_places is optional. It is the number of decimal places to round the expression to. If this parameter is omitted, then the Round function will return an integer.

Applies To

The Round function can be used in the following versions of Microsoft Access:

  • Access 2013, Access 2010, Access 2007, Access 2003, Access XP, Access 2000


Let's look at how to use the Round function in MS Access:

Round (210.67, 1)
Result: 210.7

Round (210.67, 0)
Result: 211

Round (210.67)
Result: 211

Example in VBA Code

The Round function can be used in VBA code in Microsoft Access.

For example:

Dim LNumber As Double

LNumber = Round (210.67, 1)

In this example, the variable called LNumber would now contain the value of 210.7.

Example in SQL/Queries

You can also use the Round function in a query in Microsoft Access.

For example:

Microsoft Access

In this query, we have used the Round function as follows:

Expr1: Round([UnitPrice],1)

This query will return the UnitPrice rounded to 1 decimal place and display the results in a column called Expr1. You can replace Expr1 with a column name that is more meaningful.

For example:

RoundedValue: Round([UnitPrice],1)

The results would now be displayed in a column called RoundedValue.

Frequently Asked Questions

Question: I read your explanation of the Round function using the round-to-even logic. However, I really need to round some values in the traditional sense (where 5 always rounds up). How can I do this?

Answer: You could always use the following logic:

If you wanted to round 12.65 to 1 decimal place in the traditional sense (where 12.65 rounded to 1 decimal place is 12.7, instead of 12.6), try adding 0.000001 to your number before applying the Round function:


By adding the 0.000001, the expression that you are rounding will end in 1, instead of 5...causing the Round function to round in the traditional way.

And the 0.000001 does not significantly affect the value of your expression so you shouldn't introduce any calculation errors.
