Hi @tomaxxi,

Here is the way to convert roman to int and int to roman.

RomanToInteger('MCMLXXXII');//MCMLXXXII:1982
IntegerToRoman(1982);//1982:MCMLXXXII

function RomanToInteger(str) {
    var map = { 'I': 1, 'V': 5, 'X': 10, 'L': 50, 'C': 100, 'D': 500, 'M': 1000 };
    var result = 0;

    for (var i = 0; i < str.length; i++) {
        if (i && map[str.charAt(i)] > map[str.charAt(i - 1)]) {
            result += (map[str.charAt(i)] - (map[str.charAt(i - 1)] * 2));
        }
        else {
            result += map[str.charAt(i)];
        }
    }
    return result;
}

function IntegerToRoman(num) {
    var units = ['', 'I', 'II', 'III', 'IV', 'V', 'VI', 'VII', 'VIII', 'XI'];
    var tens = ['', 'X', 'XX', 'XXX', 'XL', 'L', 'LX', 'LXX', 'LXXX', 'XC'];
    var hundreds = ['', 'C', 'CC', 'CCC', 'CD', 'D', 'DC', 'DCC', 'DCCC', 'CM'];
    var thousands = ['', 'M', 'MM', 'MMM'];

    return thousands[parseInt(num / 1000)] +
        hundreds[parseInt((num % 1000) / 100)] +
        tens[parseInt((num % 100) / 10)] +
        units[num % 10];
}
