Microsoft Excel's 'Not The Wichmann-Hill' random number generators

Abstract

Microsoft attempted to implement the Wichmann-Hill RNG in Excel 2003 and failed; it did not just produce numbers between zero and unity, it would also produce negative numbers. Microsoft issued a patch that allegedly fixed the problem so that the patched Excel 2003 and Excel 2007 now implement the Wichmann-Hill RNG, as least according to Microsoft. We show that whatever RNG it is that Microsoft has implemented in these versions of Excel, it is not the Wichmann-Hill RNG. Microsoft has now failed twice to implement the dozen lines of code that define the Wichmann-Hill RNG.
