Struct nominals::RomanUpper

pub struct RomanUpper;

Uppercase Roman numerals

This encoding utilizes Vinculum notation for numbers 4,000 and above. This notation uses an overline over a repeated set of symbols. A few examples:

use nominals::{Nominal, RomanUpper};

assert_eq!(4000_u32.to_nominal(&RomanUpper), "I̅V̅");
assert_eq!(4_001_u32.to_nominal(&RomanUpper), "I̅V̅I");
assert_eq!(2_000_000_u32.to_nominal(&RomanUpper), "M̅M̅");
