Calculation differences between PC and Windows RT computers

When you create formulas and use Excel worksheet functions on a Windows RT computer, you may see small differences between the results of its calculations and the results on PCs with traditional x86-based architecture. This is due to a difference between the design of processors used in Windows RT and x86-based computers. These differences occur at a very high level of precision, such as at the 14th or 15 significant digit.
