SUMMARY
This article contains a sample Microsoft Visual Basic for Applications function that converts an integer number to any base less than 10.



MORE INFORMATION
Microsoft provides programming examples for illustration only, without warranty either expressed or implied. This includes, but is not limited to, the implied warranties of merchantability or fitness for a particular purpose. This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements. Following is a sample function called "baseconv" that takes two arguments. The first argument, InputNum, is an integer number to be converted. The second argument, BaseNum, is the number of the base to convert InputNum to.

Sample Visual Basic Procedure
Function baseconv(InputNum, BaseNum)

Dim quotient, remainder As Single Dim answer As String quotient = InputNum  ' Set quotient to number to convert. remainder = InputNum ' Set remainder to number to convert. answer = ""

Do While quotient <> 0  ' Loop while quotient is not zero.

' Store the remainder of the quotient divided by base number in a        ' variable called remainder. remainder = quotient Mod BaseNum

' Reset quotient variable to the integer value of the quotient ' divided by base number. quotient = Int(quotient / BaseNum)

' Reset answer to contain remainder and the previous answer. answer = remainder & answer

Loop baseconv = Val(answer)  ' Convert answer variable to a number.

End Function The function should be typed in a worksheet cell as follows: =baseconv(InputNum, BaseNum) For example, the following call to the baseconv function: =baseconv(100,2) returns the following value in the cell:

1100100
