Struct nominals::RomanLower

pub struct RomanLower;

Lowercase 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, RomanLower};

assert_eq!(4_000_u32.to_nominal(&RomanLower), "i̅v̅");
assert_eq!(4_001_u32.to_nominal(&RomanLower), "i̅v̅i");
assert_eq!(2_000_000_u32.to_nominal(&RomanLower), "m̅m̅");
