VBA ROUND Function

Excel VBA Round Function

Round function in VBA is a mathematical function which as the name itself suggests it rounds up or round down the given number to the specific set of decimal places specified by the user, this function uses the logic of round even which means it takes 5 as the reference and any number with last digit after the decimal is below 5 then it is round down and vice versa.

You can round a number to a two-digit decimal, three-digit decimal, or no decimal at all. For example, if you have the number 5.8697. If you round the number to a two-digit decimal, it will be 5.87. If you round to three digits, then it will round to 5.870. If you wish to round to zero, then it will 6.-

In banking numbers, all the decimal places which are less than 0.5 will be rounded down to the previous integer value, and all the decimal places which are greater than or equal to 0.5 will be rounded up to the next integer value.

I hope you have used the ROUND function in the worksheet. In VBA, too, we can use this function, but we have a difference in these functions. We will see the difference between these two functions later in this article.

Syntax

Take a look at the syntax of the Round function.

Number: This is the number we are trying to round.

[Number of Digits after Decimal]: How many digits you need after the decimal value.

Examples

Assume you have the number 4.534, and you want to round to two digits.

Follow the below steps.

Step 1: Declare the variable as Variant.

Code:

Sub Round_Example1()

  Dim K As Variant

End Sub

Step 2: For this variable “k,” assign the value through the ROUND function.

Code:

Sub Round_Example1()
  Dim K As Variant

  K = Round(

End Sub

Step 3: Number is nothing, but what is the number we are trying to round. In this case, the number is 4.534

Code:

Sub Round_Example1()
  Dim K As Variant

  K = Round(4.534,

End Sub

Step 4: How many digits we need to round? In this case, we need to round to 2 digits.

Code:

Sub Round_Example1()
  Dim K As Variant

  K = Round(4.534, 2)

End Sub

Step 5: Now show the variable “k” value in the message box VBAMessage Box VBAVBA MsgBox function is an output function which displays the generalized message provided by the developer. This statement has no arguments and the personalized messages in this function are written under the double quotes while for the values the variable reference is provided.read more.

Code:

Sub Round_Example1()
  Dim K As Variant

  K = Round(4.534, 2)
  MsgBox K

End Sub

Run this code and see what we get.

We got the result as 4.53 when we rounded to 2 digits.

Now I will change the number from 4.534 to 4.535. Look what happens now.

Code:

Sub Round_Example1()
  Dim K As Variant

  K = Round(4.535, 2)
  MsgBox K

End Sub

Now run the code and see what the result is.

We got the result as 4.54, one decimal higher than the previous value of 4.53. This is because, in this example, we have supplied the number like 4.535, so after the number 3 next number is 5, so it is rounded to the next number, so 3 becomes 4.

Now I will supply the number as 2.452678, and I will try to round to 3 digits.

Code:

Sub Round_Example2()
  Dim K As Variant

  K = Round(2.452678, 3)
  MsgBox K

End Sub

Run this code to see the result.

The result is 2.453.

2.452678 Here numbers after the 2^nd decimal place are 2678. After number 2, the next number is 6, which is greater than or equal to 5, so it is rounded up to the next decimal number.

Now I will use the same number to round to zero and see what happens.

Code:

Sub Round_Example3()
  Dim K As Variant

  K = Round(2.452678, 0)
  MsgBox K

End Sub

Run the code and see what we get.

Since I have used the round to zero, we got the result as 2.

The reason why we got the result as 2 because here, the decimal first number is 4, which is less than the 0.5, so it is rounded down.

Difference Between Excel and VBA ROUND Function

There are mainly 2 differences.

#1 – Syntax of Both the Functions:

If you look at the syntax of both the function, we have a difference here.

Excel Round Syntax: Round (Number, Number of Digits After Decimal)

VBA Round Syntax: Round (Number, [Number of Digits After Decimal])

In excel, both the arguments are mandatory but in VBA second argument is optional.

In VBA, if you ignore the second argument, it takes the default argument as zero, so we will get the whole number.

#2 – Results:

The results given by these two functions are different. Below are a few examples
