New Calculator Handles Disjoint Interval Sets
The creator of a new calculator, who has been studying interval arithmetic for weeks, has built a tool that accurately handles division by intervals containing zero. Computing 1 / [-1, 2] yields [-∞, -1] U [0.5, +∞], a union of two disjoint intervals.
The calculator, posted on Show HN and available open-source, was built with TypeScript. The author notes that standard interval arithmetic poorly handles division by intervals containing zero, a problem their calculator addresses.
The calculator’s implementation ensures accuracy using IEEE 754 double precision floats with outward rounding. This development could significantly impact fields requiring precise computations.
