软件包摘要
Arbitrary-precision unit-aware calculator
历史
项目历史与用法
fend is an arbitrary-precision, unit-aware calculator available as a CLI, web app, Rust crate family, WebAssembly package, and packaged desktop/server-side tool.
项目历史
The GitHub release history starts with v0.1.0 on 2020-08-31. Early releases built up the calculator core, REPL behavior, history handling, terminal color, configuration support, and unit operations.
By 2022, fend had added automatic currency exchange-rate downloads and file input. Later releases expanded into custom units, decimal separator options, roman numerals, number-to-words conversion, scripting-oriented print functions, web UI improvements, and more reliable exchange-rate sourcing.
The 1.x series remains active. The changelog lists v1.5.8 on 2026-01-24, with fixes and improvements around TLS defaults, the interactive clear command, significant-figure rounding, pi precision, currency conversions, Turkish lira aliases, variable serialization, and performance.
采用历史
The official README documents package-manager installation through Homebrew, MacPorts, AUR, AOSC OS, Void Linux xbps, Nix, Cargo, Windows Package Manager, Chocolatey, Scoop, and Pkgx, alongside manual binaries from GitHub releases.
fend also appears beyond the CLI: the README lists the web interface, npm WebAssembly packages, a Telegram bot, and projects using fend such as MicroPad, Fendesk, metasearch2, FendApp, and Asleh.
使用方式
fend is used as a REPL or one-shot calculator for exact arithmetic, complex numbers, units, base conversion, dice notation, variables, trigonometric functions, strings, custom units, currency conversion, and small scripts.
The manual documents a CLI configuration file at OS-specific paths, with options for colors, history length, prompt text, internet access, exchange-rate source, decimal separator style, custom units, and related behavior. It also stores command history under the user's state directory by default.
为什么软件包爱好者会关心
fend is the sort of package nerds like because it replaces a pile of ad hoc shell, Python, bc, units, and browser-tab calculations with one small executable that understands dimensions and keeps exact arithmetic where possible.
It also shows a modern packaging pattern for Rust tools: a single core used by CLI, web, Wasm, bot, and package-manager distributions, with release notes that track both mathematical correctness and platform packaging details.
