Its package history is unusually old-school: a Unix mathematical tool maintained through tarballs, mirrors, distro packages, and now GitHub releases. ### プロジェクトの歴史 The official author page says most of calc was written by David I. Bell, with source and releases maintained by Landon Curt Noll, and credits Ernest W. Bowen plus others for numerical and help-file improvements. It also notes that portions derived from earlier public-domain arbitrary-precision routines posted to the net around 1984, though little recognizable code remained. The official README presents calc as an interactive calculator that can also execute a single command from the shell. It supports huge integer arithmetic, exact fractions, complex numbers, transcendental functions, variables, loops, and user-defined functions in a C-like language. The current CHANGES file shows active maintenance into the 2020s, including XDG Base Directory support and a 2026 2.17.0.0 line that synchronizes changes from the newer 3.0 work while keeping a legacy branch for very old systems. ### 採用の歴史 calc has been packaged broadly across Unix-like systems because it fills the gap between simple desk calculators, `bc`, and larger computer algebra systems. The repository README gives install examples for yum, pacman, apt, dnf, Termux, and source builds, matching its presence in many package managers. Its adoption is strongest among users who want scriptable exact arithmetic without pulling in a full CAS. Landon Curt Noll's pages also connect calc scripts to large-prime and astronomical interests, a good example of how small Unix math tools become personal research infrastructure. ### 使われ方 Users run `calc` interactively, pass an expression as a command-line argument, or write scripts in calc's C-like language. Typical package-manager usage is installing the binary and then relying on it for precise integer, rational, modular, complex, and high-precision floating calculations. The tool supports startup configuration through `calcrc` paths, with recent release notes documenting XDG Base Directory adoption alongside the older `~/.calcrc` convention. ### パッケージ好きにとっての重要性 calc matters to package nerds because it is a preserved lineage of pre-Git, pre-GitHub Unix numerics that still receives modern portability work. It is not just another calculator: it is a programmable arbitrary-precision environment small enough for base developer workflows. It is also a reminder that package ecosystems carry historical software forward. The same package is at home in Debian, Fedora, Arch, Homebrew, MacPorts, Nix, Termux, and source tarballs, because the CLI contract has stayed useful for decades. ### タイムライン - 1984: Earlier public-domain arbitrary-precision routines were posted to the net, later influencing calc's ancestry. - 1990s-2000s: calc circulated as source, binaries, and mirrored tarballs maintained by Landon Curt Noll. - 2022: Official calc web pages point users to GitHub releases and the GitHub source repository. - 2026: CHANGES documents calc 2.17.0.0 work, including C17 expectations, XDG Base Directory support, and a legacy branch for old systems. ### Related projects - Related tools include `bc`, `dc`, GNU bc, PARI/GP, Python's decimal and fractions modules, Maxima, and small Unix math utilities. calc occupies the middle ground: scriptable and exact like `bc`, but with a richer C-like language and built-in math library. ### ソース - - - - - ## セキュリティノート calc に一致するローカルシークレット処理マニフェストは見つかりませんでした。将来の対応で安定したパッケージ URL を使えるよう、Nucleus パッケージメタデータはここに公開されています。 ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
