5 Ways To Round Up In Excel Vba

When working with numbers in Excel VBA, rounding values is a common task. Rounding can be necessary for various reasons, such as simplifying calculations, reducing decimal places, or meeting specific formatting requirements. Excel VBA provides several methods to round up numbers, each with its own strengths and use cases. Here, we'll explore five ways to round up in Excel VBA, including their syntax, examples, and practical applications.

1. Using the RoundUp Function

The RoundUp function is a part of the WorksheetFunction object in Excel VBA. It rounds a number up to the nearest multiple of a specified value.

Sub RoundUpExample()
    Dim num As Double
    num = 12.345
    
    ' Round up to the nearest integer
    MsgBox WorksheetFunction.RoundUp(num, 0)
    
    ' Round up to the nearest tenth
    MsgBox WorksheetFunction.RoundUp(num, 1)
End Sub

Syntax:

WorksheetFunction.RoundUp(Number, Num_digits)

Number: The number to be rounded up.
Num_digits: The number of digits to round up to.

2. Using the Ceiling Function

The Ceiling function is another part of the WorksheetFunction object in Excel VBA. It returns the smallest integer that is greater than or equal to a given number.

Sub CeilingExample()
    Dim num As Double
    num = 12.345
    
    ' Round up to the nearest integer
    MsgBox WorksheetFunction.Ceiling(num)
    
    ' Round up to the nearest multiple of 5
    MsgBox WorksheetFunction.Ceiling(num, 5)
End Sub

Syntax:

WorksheetFunction.Ceiling(Number, [Significance])

Number: The number to be rounded up.
[Significance]: The multiple to which the number should be rounded up.

3. Using the Application.WorksheetFunction.RoundUp Method

The Application.WorksheetFunction.RoundUp method in Excel VBA

This method is similar to the WorksheetFunction.RoundUp function but is accessed through the Application object.

Sub ApplicationRoundUpExample()
    Dim num As Double
    num = 12.345
    
    ' Round up to the nearest integer
    MsgBox Application.WorksheetFunction.RoundUp(num, 0)
    
    ' Round up to the nearest tenth
    MsgBox Application.WorksheetFunction.RoundUp(num, 1)
End Sub

Syntax:

Application.WorksheetFunction.RoundUp(Number, Num_digits)

Number: The number to be rounded up.
Num_digits: The number of digits to round up to.

4. Using VBA's Built-in Round Function

VBA has its own Round function, which can be used to round numbers up or down.

Sub VARoundExample()
    Dim num As Double
    num = 12.345
    
    ' Round to the nearest integer
    MsgBox Round(num)
    
    ' Round to the nearest tenth
    MsgBox Round(num, 1)
End Sub

Syntax:

Round(Number, [Num_digits])

Number: The number to be rounded.
[Num_digits]: The number of digits to round to.

Note that this function does not always round up; it rounds to the nearest value based on the specified number of digits.

5. Using a Custom VBA Function

If you need more control over the rounding process or want to create a reusable function, you can create a custom VBA function.

Function RoundUpCustom(num As Double, Optional digits As Integer = 0) As Double
    RoundUpCustom = WorksheetFunction.RoundUp(num, digits)
End Function

Syntax:

RoundUpCustom(Number, [Num_digits])

Number: The number to be rounded up.
[Num_digits]: The number of digits to round up to.

This custom function uses the WorksheetFunction.RoundUp function but allows for more flexibility and readability in your code.
