Methods of Rounding Numbers in Excel VBA

There are several methods of rounding numbers in Excel VBA, each with its unique advantages and use cases.

1. Round Function

The Round function is the most commonly used method for rounding numbers in Excel VBA. The syntax for the Round function is:

Round(number, num_digits)

• number is the value to be rounded.
• num_digits is the number of digits to round to.

For example:

Sub RoundNumber()
    Dim num As Double
    num = 123.456
    MsgBox Round(num, 2) ' Output: 123.46
End Sub

2. WorksheetFunction.Round

The WorksheetFunction.Round method is similar to the Round function, but it uses the WorksheetFunction object to access the Round method.

Sub RoundNumber()
    Dim num As Double
    num = 123.456
    MsgBox WorksheetFunction.Round(num, 2) ' Output: 123.46
End Sub

3. Format Function

The Format function can be used to round numbers by specifying the number of decimal places.

Sub RoundNumber()
    Dim num As Double
    num = 123.456
    MsgBox Format(num, "0.00") ' Output: 123.46
End Sub

4. Fixed Function

The Fixed function rounds a number to a specified number of decimal places and returns the result as a string.

Sub RoundNumber()
    Dim num As Double
    num = 123.456
    MsgBox Fixed(num, 2) ' Output: 123.46
End Sub
