Numerus

Dart extensions for translating decimal numbers to Roman numerals and vice versa.

Negative numbers and numbers greater than 65535 are not supported. Functions will return null in place of generating nonsense,

Examples

import 'package:numerus/numerus.dart';

main() {
  var n = 418;
  print(n.toRomanNumeralString());
  // 'CDXVIII'

  var str = 'CDXVIII';
  print(str.isValidRomanNumeral());
  // true
  print(str.toRomanNumeralValue());
  // 418  
}
