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. The number on
every D{N} type is MAX_SCALE — the highest SCALE the storage can hold.
| Type | Storage | MAX_SCALE | Feature gate |
|---|---|---|---|
D9<SCALE> | i32 | 9 | always on |
D18<SCALE> | i64 | 18 | always on |
D38<SCALE> | i128 | 38 | always on |
D57<SCALE> | 192-bit | 57 | d57 or wide |
D76<SCALE> | 256-bit | 76 | d76 or wide |
D115<SCALE> | 384-bit | 115 | d115 or wide |
D153<SCALE> | 512-bit | 153 | d153 or wide |
D230<SCALE> | 768-bit | 230 | d230 or wide |
D307<SCALE> | 1024-bit | 307 | d307 or wide |
D462<SCALE> | 1536-bit | 462 | d462 or x-wide |
D616<SCALE> | 2048-bit | 616 | d616 or x-wide |
D924<SCALE> | 3072-bit | 924 | d924 or xx-wide |
D1232<SCALE> | 4096-bit | 1232 | d1232 or xx-wide |
Umbrellas: wide enables D57 / D76 / D115 / D153 / D230 / D307;
x-wide adds D462 + D616; xx-wide adds D924 + D1232. Every
adjacent pair has lossless .widen() / fallible .narrow()
helpers plus From / TryFrom impls.
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 platformf64intrinsics.alloc: pulled in automatically; required for string formatting and parsing.serde: enablesserde_helpersfor serialisation and deserialisation.strict: enables integer-only implementations of all transcendental functions. Whenstrictis active each function that would otherwise route throughf64is 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.strictdoes not requirestd; the integer transcendental implementations compile underno_std + alloc.
