tuppu-scalar

Exact scalar arithmetic with rational numbers and uncertainty tracking for geometric algebra.

Part of the Tuppu Nabu geometric algebra system.

Features

• Exact rational arithmetic — No floating-point errors
• Symbolic constants — π, √2, √3 preserved exactly
• Uncertainty tracking — Propagate measurement uncertainty
• Clean API — Natural Rust operators

Usage

use tuppu_scalar::Scalar;

let a = Scalar::from(3) / Scalar::from(7);
let b = Scalar::pi() / Scalar::from(4);

// Exact arithmetic — no floating point errors
assert_eq!(a * Scalar::from(7), Scalar::from(3));
