软件包摘要

Command-line streaming exact real calculator

命令和别名

  • spigot

历史

项目历史与用法

spigot is Simon Tatham's command-line exact real calculator, aimed at producing verified digits from mathematical expressions rather than fast floating-point approximations.

项目历史

The official page describes spigot as a streaming exact real calculator named after Jeremy Gibbons's unbounded spigot algorithm for digits of pi, expanded to support more output modes and input numbers.

采用历史

The project is distributed from the author's site as a Unix source archive and Windows executable, with official development sources in a Tartarus git repository. The input package facts show it packaged in Homebrew, Debian, Nix, and Ubuntu.

使用方式

The manual documents an expression language, output modes, rounding modes, file and pipe input, and a Unix man-page appendix. Its niche is slow but exact calculation, especially for many digits, numerically fragile expressions, or cross-checking another system.

为什么软件包爱好者会关心

For package people, spigot is the pleasing sort of small CLI that rewards being packaged: mathematically specialized, scriptable, source-distributed, and useful as a reproducibility check when ordinary calculators hide rounding behavior.
