decimal-scaled 0.2.5

//! Const-generic base-10 fixed-point decimal types for deterministic arithmetic.
//!
//! # Overview
//!
//! `decimal-scaled` provides a family of fixed-point decimal types whose stored
//! integer encodes `actual_value * 10^SCALE`. Decimal literals like `1.1`
//! round-trip exactly without any binary approximation, and all core arithmetic
//! is integer-only — identical bit-patterns on every platform.
//!
//! # Primary types
//!
//! Each width has a `D<digits><const SCALE: u32>` const-generic shape with the
//! same method surface; pick the narrowest that fits your range.
//!
//! | Type | Storage | Max safe decimal digits | Feature gate |
//! |------|---------|-------------------------|--------------|
//! | [`D9<SCALE>`]  | `i32`    | 9   | always on |
//! | [`D18<SCALE>`] | `i64`    | 18  | always on |
//! | [`D38<SCALE>`] | `i128`   | 38  | always on |
//! | [`D76<SCALE>`] | 256-bit  | 76  | `d76` or `wide` |
//! | [`D153<SCALE>`] | 512-bit | 153 | `d153` or `wide` |
//! | [`D307<SCALE>`] | 1024-bit | 307 | `d307` or `wide` |
//!
//! Concrete scale aliases such as `D38s12 = D38<12>` are emitted for every
//! supported `SCALE`. `SCALE = MAX_SCALE + 1` is rejected at compile time —
//! `10^(MAX_SCALE+1)` overflows the storage type.
//!
//! The width-generic [`Decimal`] trait carries the surface that is identical
//! across widths (constants, arithmetic operators, sign methods, integer
//! variants, pow / checked / wrapping / saturating / overflowing, float bridge,
//! Euclidean / floor / ceil division, etc.). Use it to write helpers that work
//! across widths; reach for the concrete type for width-specific operations
//! like `rescale::<TARGET>()` whose const-generic parameter cannot live on a
//! trait method.
//!
//! # Equality and hashing
//!
//! Because each logical value has exactly one representation at a fixed scale,
//! `Hash`, `Eq`, `PartialEq`, `PartialOrd`, and `Ord` are all derived from the
//! underlying integer storage. Two `Dxx<S>` values compare equal if and only
//! if their raw bit patterns are identical. This gives predictable behaviour
//! when decimal values are used as `HashMap` keys, unlike variable-scale
//! decimal types where `1.10` and `1.1` may hash differently.
//!
//! # `num-traits` compatibility
//!
//! Every width implements the standard `num-traits` 0.2 surface:
//! `Zero`, `One`, `Num`, `Bounded`, `Signed`, `FromPrimitive`,
//! `ToPrimitive`, and the `Checked{Add,Sub,Mul,Div,Rem,Neg}` family
//! (see [`::num_traits`]). These impls are unconditional (not behind a
//! feature flag) because generic numeric code in the wider ecosystem
//! consumes this surface by default.
//!
//! # `no_std` support
//!
//! The crate compiles with `no_std + alloc` when default features are
//! disabled. `alloc` is required for `Display::to_string` and
//! `FromStr::from_str`. Targets without `alloc` are not supported.
//!
//! # Feature flags
//!
//! - `std` (default): enables the fast implementations of transcendental
//! functions (trigonometry, logarithms, exponentials, square root, cube
//! root, float power) that delegate to platform `f64` intrinsics.
//! - `alloc`: pulled in automatically; required for string formatting and
//! parsing.
//! - `serde`: enables `serde_helpers` for serialisation and deserialisation.
//! - `strict`: enables integer-only implementations of all transcendental
//! functions. When `strict` is active each function that would otherwise
//! route through `f64` is instead implemented using integer-only
//! algorithms. Explicit float-conversion methods (`to_f64`,
//! `from_f64`, etc.) remain available regardless; they are type
//! conversions, not mathematical operations. `strict` does not require
//! `std`; the integer transcendental implementations compile under
//! `no_std + alloc`.
