WhatA static analysis tool or language plugin that uses interval arithmetic to detect unreachable code branches, integer overflows, and division-by-zero errors at compile time.
SignalMultiple commenters independently described real applications of interval arithmetic in static analysis and type checking — tracking value ranges through code paths to prove branches unreachable or flag potential runtime errors — suggesting this is a recognized but underserved need among compiler and tooling developers.
Why NowMemory safety and correctness are dominating the systems programming conversation (Rust adoption, White House memo on memory-safe languages), and AI-assisted coding is generating more code that needs automated verification.
MarketEnterprise software teams and safety-critical industries (automotive, aerospace, medical devices) paying for static analysis; ~$3B SAST market; competes with Coverity, CodeSonar, and Polyspace but interval-based analysis is largely absent from mainstream tools.
MoatIntegration into CI/CD pipelines creates high switching costs, and a comprehensive interval-arithmetic-based analysis engine requires deep numerical computing expertise that is scarce.
