## Projektgeschichte und Nutzung

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

### Projektgeschichte

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.

### Adoptionsgeschichte

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.

### Wie es verwendet wird

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.

### Warum Paket-Nerds sich dafür interessieren

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.

### Zeitleiste
