Buying WTH: Javascript to VBA for Excel

I need a Javascript (few lines of code) translated to Excel VBA, to be run as UDF, user defined function.

The javascript code is: http://jsfiddle.net/49Xks/

The code should be a function like the one below, so that it can be inserted with Alt + F11, Insert --> Module

Function stringOfUniques(inputString As String) As String
    Dim inArray() As String
    ...
End Function

Code (markup):

I need only a slight modification of the linked script Instead of

document.write(fractionToDecimal(223,7) + "<br>\n");

Code (markup):

(for example), the code I need should take the nominator, e.g. 223, from cell A1 in Excel, and the denominator, e.g. 7, from cell B1.

If you can do that get in touch in Skype: markmu1965
