# Fixed-point numbers
|
||
|
||
The [*fixed* crate] provides fixed-point numbers.
|
||
|
||
* [`FixedI8`] and [`FixedU8`] are eight-bit fixed-point numbers.
|
||
* [`FixedI16`] and [`FixedU16`] are 16-bit fixed-point numbers.
|
||
* [`FixedI32`] and [`FixedU32`] are 32-bit fixed-point numbers.
|
||
* [`FixedI64`] and [`FixedU64`] are 64-bit fixed-point numbers.
|
||
* [`FixedI128`] and [`FixedU128`] are 128-bit fixed-point numbers.
|
||
|
||
An <i>n</i>-bit fixed-point number has <i>f</i> = `Frac` fractional
|
||
bits where 0 ≤ <i>f</i> ≤ <i>n</i>, and
|
||
<i>n</i> − <i>f</i> integer bits. For example,
|
||
<code>[FixedI32]\<[U24]></code> is a 32-bit signed fixed-point number with
|
||
<i>n</i> = 32 total bits, <i>f</i> = 24 fractional bits, and
|
||
<i>n</i> − <i>f</i> = 8 integer bits.
|
||
<code>[FixedI32]\<[U0]></code> behaves like [`i32`], and
|
||
<code>[FixedU32]\<[U0]></code> behaves like [`u32`].
|
||
|
||
The difference between any two successive representable numbers is constant
|
||
throughout the possible range for a fixed-point number:
|
||
<i>Δ</i> = 1/2<sup><i>f</i></sup>. When <i>f</i> = 0, like
|
||
in <code>[FixedI32]\<[U0]></code>, <i>Δ</i> = 1 because representable
|
||
numbers are integers, and the difference between two successive integers is 1.
|
||
When <i>f</i> = <i>n</i>, <i>Δ</i> = 1/2<sup><i>n</i></sup>
|
||
and the value lies in the range −0.5 ≤ <i>x</i> < 0.5
|
||
for signed numbers like <code>[FixedI32]\<[U32]></code>, and in the range
|
||
0 ≤ <i>x</i> < 1 for unsigned numbers like
|
||
<code>[FixedU32]\<[U32]></code>.
|
||
|
||
The main features are
|
||
|
||
* Representation of binary fixed-point numbers up to 128 bits wide.
|
||
* Conversions between fixed-point numbers and numeric primitives.
|
||
* Comparisons between fixed-point numbers and numeric primitives.
|
||
* Parsing from strings in decimal, binary, octal and hexadecimal.
|
||
* Display as decimal, binary, octal and hexadecimal.
|
||
* Arithmetic and logic operations.
|
||
|
||
This crate does *not* provide decimal fixed-point numbers. For example 0.001
|
||
cannot be represented exactly, as it is 1/10<sup>3</sup>. It is binary fractions
|
||
like 1/2<sup>4</sup> (0.0625) that can be represented exactly, provided there
|
||
are enough fractional bits.
|
||
|
||
This crate does *not* provide general analytic functions.
|
||
|
||
* No algebraic functions are provided, for example no `pow`.
|
||
* No trigonometric functions are provided, for example no `sin` or `cos`.
|
||
* No other transcendental functions are provided, for example no `log` or
|
||
`exp`.
|
||
|
||
These functions are not provided because different implementations can have
|
||
different trade-offs, for example trading some correctness for speed.
|
||
Implementations can be provided in other crates.
|
||
|
||
* The [*cordic* crate] provides various functions implemented using the
|
||
[CORDIC] algorithm.
|
||
|
||
The conversions supported cover the following cases.
|
||
|
||
* Infallible lossless conversions between fixed-point numbers and numeric
|
||
primitives are provided using [`From`] and [`Into`]. These never fail
|
||
(infallible) and do not lose any bits (lossless).
|
||
* Infallible lossy conversions between fixed-point numbers and numeric
|
||
primitives are provided using the [`LossyFrom`] and [`LossyInto`] traits.
|
||
The source can have more fractional bits than the destination.
|
||
* Checked lossless conversions between fixed-point numbers and numeric
|
||
primitives are provided using the [`LosslessTryFrom`] and
|
||
[`LosslessTryInto`] traits. The source cannot have more fractional bits than
|
||
the destination.
|
||
* Checked conversions between fixed-point numbers and numeric primitives are
|
||
provided using the [`FromFixed`] and [`ToFixed`] traits, or using the
|
||
[`from_num`] and [`to_num`] methods and [their checked
|
||
versions][`checked_from_num`].
|
||
* Additionally, [`az`] casts are implemented for conversion between
|
||
fixed-point numbers and numeric primitives.
|
||
* Fixed-point numbers can be parsed from decimal strings using [`FromStr`],
|
||
and from binary, octal and hexadecimal strings using the
|
||
[`from_str_binary`], [`from_str_octal`] and [`from_str_hex`] methods. The
|
||
result is rounded to the nearest, with ties rounded to even.
|
||
* Fixed-point numbers can be converted to strings using [`Display`],
|
||
[`Binary`], [`Octal`], [`LowerHex`], [`UpperHex`], [`LowerExp`] and
|
||
[`UpperExp`]. The output is rounded to the nearest, with ties rounded to
|
||
even.
|
||
* All fixed-point numbers are plain old data, so [`bytemuck`] bit casting
|
||
conversions can be used.
|
||
|
||
## What’s new
|
||
|
||
### Version 1.29.0 news (2025-02-26)
|
||
|
||

|
||
[`Fixed`][tf-1-29] trait, and to the [`Saturating`][s-1-29],
|
||
[`Wrapping`][w-1-29] and [`Unwrapped`][u-1-29] wrappers:
|

|
||
[`wrapping_from_ascii_hex`][f-wfah-1-29]
|
||
* [`unwrapped_from_ascii`][f-ufa-1-29],
|
||
[`unwrapped_from_ascii_binary`][f-ufab-1-29],
|
||
[`unwrapped_from_ascii_octal`][f-ufao-1-29],
|
||
[`unwrapped_from_ascii_hex`][f-ufah-1-29]
|
||
* [`overflowing_from_ascii`][f-ofa-1-29],
|
||
[`overflowing_from_ascii_binary`][f-ofab-1-29],
|
||
[`overflowing_from_ascii_octal`][f-ofao-1-29],
|
||
[`overflowing_from_ascii_hex`][f-ofah-1-29]
|
||
* The [`cast_unsigned`][f-cu-1-29] method was added to all signed fixed-point
|
||
numbers, to their [`Saturating`][s-1-29], [`Wrapping`][w-1-29] and
|
||
[`Unwrapped`][u-1-29] wrappers, and to the [`Fixed`][tf-1-29] trait.
|
||
* The [`cast_signed`][f-cs-1-29] method was added to all unsigned fixed-point
|
||
numbers, to their [`Saturating`][s-1-29], [`Wrapping`][w-1-29] and
|
||
[`Unwrapped`][u-1-29] wrappers, and to the [`Fixed`][tf-1-29] trait.
|
||
* The following methods are now usable in constant context:
|
||
* [`mul_acc`][f-ma-1-29], [`checked_mul_acc`][f-cma-1-29],
|
||
[`saturating_mul_acc`][f-sma-1-29], [`wrapping_mul_acc`][f-wma-1-29],
|
||
[`unwrapped_mul_acc`][f-uma-1-29], [`overflowing_mul_acc`][f-oma-1-29]
|
||
* Now [`ParseFixedError`][pfe-1-29] implements [`Error`] even when the `std`
|
||
[optional feature][feat-1-29] is disabled.

### Other releases
|
||
|
||
Details on other releases can be found in [*RELEASES.md*].
|
||
|
||
[*RELEASES.md*]: https://gitlab.com/tspiteri/fixed/blob/master/RELEASES.md
|
||
|
||
## Quick examples
|
||
|
||
```rust
|
||
use fixed::types::I20F12;
|
||
|
||
// 19/3 = 6 1/3
|
||
let six_and_third = I20F12::from_num(19) / 3;
|
||
// four decimal digits for 12 binary digits
|
||
assert_eq!(six_and_third.to_string(), "6.3333");
|
||
// find the ceil and convert to i32
|
||
assert_eq!(six_and_third.ceil().to_num::<i32>(), 7);
|
||
// we can also compare directly to integers
|
||
assert_eq!(six_and_third.ceil(), 7);
|
||
```
|
||
|
||
The type [`I20F12`] is a 32-bit fixed-point signed number with 20 integer bits
|
||
and 12 fractional bits. It is an alias to <code>[FixedI32]\<[U12]></code>. The
|
||
unsigned counterpart would be [`U20F12`]. Aliases are provided for all
|
||
combinations of integer and fractional bits adding up to a total of eight, 16,
|
||
32, 64 or 128 bits.
|
||
|
||
```rust
|
||
use fixed::types::{I4F4, I4F12};
|
||
|
||
// -8 ≤ I4F4 < 8 with steps of 1/16 (~0.06)
|
||
let a = I4F4::from_num(1);
|
||
// multiplication and division by integers are possible
|
||
let ans1 = a / 5 * 17;
|
||
// 1 / 5 × 17 = 3 2/5 (3.4), but we get 3 3/16 (~3.2)
|
||
assert_eq!(ans1, I4F4::from_bits((3 << 4) + 3));
|
||
assert_eq!(ans1.to_string(), "3.2");
|
||
|
||
// -8 ≤ I4F12 < 8 with steps of 1/4096 (~0.0002)
|
||
let wider_a = I4F12::from(a);
|
||
let wider_ans = wider_a / 5 * 17;
|
||
let ans2 = I4F4::from_num(wider_ans);
|
||
// now the answer is the much closer 3 6/16 (~3.4)
|
||
assert_eq!(ans2, I4F4::from_bits((3 << 4) + 6));
|
||
assert_eq!(ans2.to_string(), "3.4");
|
||
```
|
||
|
||
The second example shows some precision and conversion issues. The low precision
|
||
of `a` means that `a / 5` is 3⁄16 instead of 1⁄5, leading to an inaccurate
|
||
result `ans1` = 3 3⁄16 (~3.2). With a higher precision, we get `wider_a / 5`
|
||
equal to 819⁄4096, leading to a more accurate intermediate result `wider_ans` =
|
||
3 1635⁄4096. When we convert back to four fractional bits, we get `ans2` = 3
|
||
6⁄16 (~3.4).
|
||
|
||
Note that we can convert from [`I4F4`] to [`I4F12`] using [`From`], as the
|
||
target type has the same number of integer bits and a larger number of
|
||
fractional bits. Converting from [`I4F12`] to [`I4F4`] cannot use [`From`] as we
|
||
have less fractional bits, so we use [`from_num`] instead.
|
||
|
||
## Writing fixed-point constants and values literally
|
||
|
||
The [`lit`] method, which is available as a `const` function, can be used to
|
||
parse literals. It supports
|
||
* underscores as separators;
|
||
* prefixes “`0b`”, “`0o`” and “`0x`” for binary, octal and hexadecimal
|
||
numbers;
|
||
* an optional decimal exponent with separator “`e`” or “`E`” for decimal,
|
||
binary and octal numbers, or with separator “`@`” for all supported radices
|
||
including hexadecimal.
|
||
|
||
```rust
|
||
use fixed::types::I16F16;
|
||
|
||
// 0.1275e2 is 12.75
|
||
const TWELVE_POINT_75: I16F16 = I16F16::lit("0.127_5e2");
|
||
// 1.8 hexadecimal is 1.5 decimal, and 18@-1 is 1.8
|
||
const ONE_POINT_5: I16F16 = I16F16::lit("0x_18@-1");
|
||
// 12.75 + 1.5 = 14.25
|
||
let sum = TWELVE_POINT_75 + ONE_POINT_5;
|
||
assert_eq!(sum, 14.25);
|
||
```
|
||
|
||
## Using the *fixed* crate
|
||
|
||
The *fixed* crate is available on [crates.io][*fixed* crate]. To use it in your
|
||
crate, add it as a dependency inside [*Cargo.toml*]:
|
||
|
||
```toml
|
||
[dependencies]
|
||
fixed = "1.29"
|
||
```
|
||
|
||
The *fixed* crate requires rustc version 1.83.0 or later.
|
||
|
||
## Optional features
|
||
|
||
The *fixed* crate has these optional feature:
|
||
|
||
1. `arbitrary`, disabled by default. This provides the generation of arbitrary
|
||
fixed-point numbers from raw, unstructured data. This feature requires the
|
||
[*arbitrary* crate].
|
||
2. `borsh`, disabled by default. This implements serialization and
|
||
deserialization using the [*borsh* crate].
|
||
3. `serde`, disabled by default. This provides serialization support for the
|
||
fixed-point types. This feature requires the [*serde* crate].
|
||
4. `std`, disabled by default. This is for features that are not possible under
|
||
`no_std`: currently this is only required for the `serde-str` feature.
|
||
5. `serde-str`, disabled by default. Fixed-point numbers are serialized as
|
||
strings showing the value when using human-readable formats. This feature
|
||
requires the `serde` and the `std` optional features. **Warning:** numbers
|
||
serialized when this feature is enabled cannot be deserialized when this
|
||
feature is disabled, and vice versa.
|
||
|
||
To enable features, you can add the dependency like this to [*Cargo.toml*]:
|
||
|
||
```toml
|
||
[dependencies.fixed]
|
||
features = ["serde"]
|
||
version = "1.29"
|
||
```
|
||
|
||
## Experimental optional features
|
||
|
||
It is not considered a breaking change if the following experimental features
|
||
are removed. The removal of experimental features would however require a minor
|
||
version bump. Similarly, on a minor version bump, optional dependencies can be
|
||
updated to an incompatible newer version.
|
||
|
||
1. `num-traits`, disabled by default. This implements some traits from the
|
||
[*num-traits* crate]. (The plan is to promote this to an optional feature
|
||
once the [*num-traits* crate] reaches version 1.0.0.)
|
||
2. `nightly-float`, disabled by default. This requires the nightly compiler,
|
||
and implements conversions and comparisons with the experimental [`f16`] and
|
||
[`f128`] primitives. (The plan is to always implement the conversions and
|
||
comparisons and remove this experimental feature once the primitives are
|
||
stabilized.)
|
||
|
||
[`f128`]: https://doc.rust-lang.org/nightly/std/primitive.f128.html
|
||
[`f16`]: https://doc.rust-lang.org/nightly/std/primitive.f16.html
|
||
|
||
## Deprecated optional features
|
||
|
||
The following optional features are deprecated and will be removed in the next
|
||
major version of the crate.
|
||
|
||
1. `az`, has no effect. Previously required for the [`az`] cast traits. Now
|
||
these cast traits are always provided.
|
||
2. `f16`, has no effect. Previously required for conversion to/from
|
||
<code>[half]::[f16][half::f16]</code> and
|
||
<code>[half]::[bf16][half::bf16]</code>. Now these conversions are always
|
||
provided.
