Excel VBA Integer

Data types are so important in any coding language because all the variable declaration should be followed by data type assigning to those variables. We have several data types to work with and each data type has its own advantages and disadvantages associated with it. When we are declaring variables is important to know details about the particular data type. This is the article dedicated for “Integer” data type in VBA. We will show you the complete picture of “Integer” data type.

What is the Integer Data Type?

Integers are whole numbers which could be positive, negative, and zero but not a fractional number. In VBA context “Integer” is a data type we assign to the variables. It is a numerical data type which can hold of whole numbers without decimal positions. Integer data type 2 bytes of storage which is half of the VBA LONG datatype i.e. 4 bytes.

Examples of Excel VBA Integer Data Type

Below are the examples of Vba Integer Data type.

Example #1

When we declare a variable it is necessary to assign a data type to it and integer one of them which is commonly used by all the users based on the requirements.

As I told integer can only hold of whole numbers, not any fractional numbers. Follow the below steps to see the example of a VBA integer data type.

Step 1: Declare the variable as Integer.

Code:

Sub Integer_Example()

  Dim k As Integer

End Sub

VBA Integer Example 1

Step 2: Assign the value of 500 to the variable “k”.

Code:

Sub Integer_Example1()

  Dim k As Integer

  k = 500

End Sub

VBA Integer Example 1-1

Step 3: Show the value in the VBA message box.

Code:

Sub Integer_Example1()

  Dim k As Integer

  k = 500

  MsgBox k

End Sub

VBA Integer Example 1-2

When we run the Code using F5 key or manually then, we can see 500 in the message box.

VBA Integer Example 1-3

Example #2

Now I will assign the value as -500 to the variable “k”.

Code:

Sub Integer_Example2()

  Dim k As Integer

  k = -500

  MsgBox k

End Sub

VBA Integer Example 2

Run this code manually or press F5 then, it will also show the value of -500 in the message box.

VBA Integer Example 2-1

Example #3

As I told VBA Integer data type can hold only whole numbers not fraction numbers like 25.655 or 47.145.

However, I will try to assign the fraction number to a VBA Integer data type. For an example look at the below code.

Code:

Sub Integer_Example3()

    Dim k As Integer

    k = 85.456

    MsgBox k

End Sub

Example 3

I have assigned 85.456 to the variable “k”. I will run this VBA code to see what the result is.

VBA Integer Example 3-1

  • It has returned the result as 85 even though I have assigned the value of the fraction number. This is because of VBA round the fraction numbers to the nearest integer.
  • All the fraction number which are less than 0.5 will be rounded down to the nearest integer. For an example 2.456 = 2, 45.475 = 45.
  • All the fraction number which are greater than 0.5 will be rounded up to the nearest integer. For an example 10.56 = 11, 14.789 = 15.

To have another look at the roundup integer lets the value of “k” to 85.58.

Code:

Sub Integer_Example3()

    Dim k As Integer

    k = 85.58

    MsgBox k

End Sub

Example 3-2

When I run this code using F5 key or manually it will return 86 because anything more than 0.5 will be rounded up to the next integer number.

VBA Integer Example 3-3

Limitations of Integer Data Type in Excel VBA

Overflow Error: Integer data type should work fine as long as the assigned value is between -32768 to 32767. The moment it crosses the limit on either side it will cause you an error.

For an example look at the below code.

Code:

Sub Integer_Example4()

    Dim k As Integer

    k = 40000

    MsgBox k

End Sub

Example 4

I have assigned the value of 40000 to the variable “k”.

Since I have complete knowledge on Integer Data Type for sure I know it doesn’t work because integer data type cannot hold the value anything more than 32767.

Let’s run the code manually or through F5 key and see what happens.

VBA Integer Example 4-1

Oops !!!

I got the error as “Overflow” because Integer data type cannot hold anything more than 32767 for positive numbers and -32768 for negative numbers.

Type Mismatch Error: Integer data can only hold numerical values between -32768 to 32767. If any number assigned more than these numbers will show Overflow error.

Now I will try to assign text or string values to it.  In the below example code I have assigned the value as “Hello”.

Code:

Sub Integer_Example4()

    Dim k As Integer

    k = "Hello"

    MsgBox k

End Sub

Example 4-2

I will run this code through run option or manually and see what happens.

VBA Integer Example 4-3

It is showing the error as “Type mismatch” because we cannot assign a text value to the variable “integer data type”.
