An executable was run on one machine with .NET 4 installed and one machine with .NET 4.5 installed. A series of calculations were performed on an identical set of inputs from one input file. The resulting numerical answers should be identical between both machines but the answers from the .NET 4.5 machine differ from those on the .NET 4 machine (which are validated to be correct). Sample output is provided in the attached forms. It cannot be determined by us which operations or functions cause this discrepancy but it has been isolated to a .NET 4 versus 4.5 issue. All testing conducted on 4 and 4.5 machines produces consistent results.
