CLI Calculator is a high‑performance, cross‑platform command‑line calculator built for precision, reproducibility, and automation‑centric workflows.

It is designed around computational transparency: evaluation rules are explicit, internal state is intentionally constrained and inspectable, and outputs are stable and predictable—whether you’re using it interactively or inside CI/CD pipelines.

What you can do

  • Explore interactively in a REPL with history and named variables
  • Evaluate expressions with strict, well-defined precedence and semantics
  • Work with matrices for common linear‑algebra tasks
  • Use number‑theory utilities like prime factorization and divisor enumeration
  • Convert numeral systems (binary, octal, decimal, hexadecimal)
  • Persist variables in human‑readable TOML for traceable state
  • Run batch scripts with lightweight control flow (@set, @if, @loop)

Why CLI Calculator

  • Deterministic by construction: predictable results, no hidden heuristics
  • Automation‑ready: integrates cleanly into shell scripts, tooling, and CI
  • Performance‑oriented: implemented in modern C++ with low overhead
  • Cross‑platform consistency: uniform behavior across Linux and Windows
  • Zero runtime dependencies: compact and portable binary

Who it’s for

  • Developers and DevOps engineers who want reliable terminal tooling
  • Students and researchers working with math, algorithms, or systems programming
  • Power users who prefer keyboard‑driven, scriptable utilities
