interval

3.2.2 (2026-02-16)

The interval package provides tools for performing interval arithmetic with real numbers. Instead of working with single values, it lets you evaluate functions over entire ranges of inputs. Because interval arithmetic tracks rounding and approximation errors automatically, all computed results are guaranteed to be correct within their bounds. This approach is useful for handling uncertainties, estimating numerical errors, and ensuring results you can rely on. It is also widely applied in areas such as computer‑assisted proofs, constraint programming, and verified computing. The package represents interval endpoints using binary64 floating‑point numbers and follows the IEEE Std 1788‑2015 standard for interval arithmetic.
