This crate provides unsigned floats by defining two wrappers - a UF32 and UF64. The type is equivalent to storing a positive number of the underlying type (f32 or f64) and no optimisations have been carried out to use the sign bit to store another bit of the data.
To use this as a dependency, add it to your Cargo.toml file:
ufo = "0.1"If you need serialization, enable the serde feature
ufo = { version = "0.1", features = ["serde"] }There is also a nightly feature that takes advantage of the TryFrom/TryInto traits
use ufo::Uf32;
fn main() {
let a = Uf32::try_new(1.0).expect("invalid number");
let b = Uf32::try_new(2.0).expect("invalid number");
assert_eq!(a + b, Uf32::try_new(3.0).expect("invalid number"))
}If you want to suggest any new feature or report a bug, you can open an issue here or drop in a pull request directly.
Right now, I still need to tests for most of the functions, so you can test it locally by running:
cargo test When submitting a Pull request, run cargo fmt on the latest nightly before committing.
