decimal-scaled 0.4.1

Const-generic base-10 fixed-point decimals (D9/D18/D38/D76/D153/D307) with integer-only transcendentals correctly rounded to within 0.5 ULP — exact at the type's last representable place. Deterministic across every platform; no_std-friendly.

//! Type definitions, per-width aliases, and per-family method shells.
//!
//! This bucket holds the generic `D<S, SCALE>` newtype, the per-width
//! aliases (`D9`, `D18`, `D38`, …), the `DecimalConstants` constants
//! surface, the public-trait surface in [`traits`], and the per-family
//! inherent-impl shells (`arithmetic`, `overflow_variants`,
//! `log_exp`, `trig`, `powers`, …).
//!
//! Lower-layer kernels live in [`crate::algos`] and routing lives in
//! [`crate::policy`]; this bucket is the typed surface that calls into
//! them.
