This is a library for various numeric systems, including ancient, modern, and just plain strange.
Although the Roman module is likely to be the most popular, I maintain an interest in the others, so they're all packaged as one!
This library uses Cargo. Just add numerals as a
dependency in your Cargo.toml:
toml
[dependencies]
numerals = "0.1"
To format a number as Roman numerals, use Roman::from to convert it, and the
UpperHex formatting trait to format it.
rust
use numerals::roman::Roman;
let string = format!("{:X}", Roman::from(134));
assert_eq!(string, "CXXXIV");
