This crate provides utilities to (round, roundup, rounddown) your floats with precision from 1 to 10.
In your project's Cargo.toml include the package name and version, like so:
rust
[dependencies]
round = "0.1.0" // or any latest version on crates.io
```rust extern crate round; use round::{round, roundup, rounddown};
fn main() { // basic rounding let testn = round(8.9534, 2); // 8.95 let testx = round(8.9536, 3); // 8.954 let test_y = round(8.9536, -1); // 8.95
// rounding up
let test_j = round_up(8.9534, 2); // 8.96
let test_k = round_up(8.9536, 3); // 8.954
// rounding down
let test_l = round_down(8.9534, 2); // 8.95
let test_m = round_down(8.9536, 3); // 8.953
} ```
defaults to 2 decimal rounding (round, roundup, rounddown) if your chosen number of decimals (i32) is negative or greater than 10.
round, roudup, rounddown from 0 to 10 precision
Turns out I am in need of this type of operation almost every day. Hopefully it will save you some time as well.
