Improving assurance of high-consequence systems using formal methods and automated reasoning 
News Article, July 14, 2025 • Error from imperfect computer representations of numbers when visualizing a sphere at 1km and 20,000km distance from an observer. Computers typically represent numbers one of two ways: fixed-point (via integers) and floating-point numbers. Floating point provides improved efficiency and productivity, but errors can accumulate if not managed carefully. Error from...
