Really insightful article about the difficulties of writing correct software - particularly in the realm of numerical calculation.
Also references an Excel 2007 calculation (display) error where the formula 850*77.1 is displayed as 100,000 (instead of 65,535)!

Excel Bugs and the intricacies in doing arithmetic efficiently and correctly. We normally take all this for granted but there's much more going on behind the scenes (especially in Mathemtica) to ensure correct arithmetic.
