A developer has created an open-source TypeScript calculator implementing interval union arithmetic, which improves upon standard interval arithmetic by handling division by zero-containing intervals and discontinuous functions through disjoint interval sets. The project is based on a 2017 academic paper and provides accurate results with IEEE 754 floating-point outward rounding. This offers practical utility for numerical analysis and mathematical computing applications.
Background
Interval arithmetic is a numerical method that represents values as ranges to track rounding errors and uncertainties, but traditional implementations struggle with division by intervals containing zero. Recent research has proposed using unions of disjoint intervals to address these limitations.
