fixed_analytics

Fixed-point mathematical functions which are accurate, fast, safe, and machine independent.

Examples

use fixed::types::I16F16;
use fixed_analytics::{sin, cos, sqrt, ln};

let angle = I16F16::from_num(0.5);
let (s, c) = (sin(angle), cos(angle));

let root = sqrt(I16F16::from_num(2.0)).unwrap();
assert!((root.to_num::<f32>() - 1.414).abs() < 0.001);

let log = ln(I16F16::E).unwrap();
assert!((log.to_num::<f32>() - 1.0).abs() < 0.01);

Installation

Requires Rust 1.88 or later.

[dependencies]
fixed_analytics = "0.4"

For no_std environments:

[dependencies]
fixed_analytics = { version = "0.4", default-features = false }

Available Functions

Fallible functions return Result<T, Error> and fail on domain violations. Total functions return T directly and handle all inputs. Functions are calculated via CORDIC, Newton-Raphson, and Taylor series techniques.

Accuracy

Relative error statistics measured against MPFR reference implementations.
