(More or less) accurate floating point algorithms
This crate provides several algorithms that implement highly accurate or even guaranteed correct sum and dot product for floating-point numbers without resorting to arbitrary precision arithmetic. These algorithms are available:
- Accurate sum and dot product, based on Ogita, Rump, and Oishi 05
- Online exact summation, based on Zhu and Hayes 10
Usage
Add the accurate
crate as a dependency in your Cargo.toml
:
[dependencies]
accurate = "0.3"
Then use it in your program like this:
extern crate accurate;
use accurate::traits::*;
use accurate::sum::Sum2;
fn main() {
let x = vec![1.0, 2.0, 3.0];
let s = x.sum_with_accumulator::<Sum2<_>>();
assert_eq!(6.0f64, s);
}
