Converting integers to roman numerals

Question

I\'m trying to write a function that converts numbers to roman numerals. This is my code so far; however, it only works with numbers that are less than 400. Is there a quick

Answer 1

Here is the version from @Cammilius converted to C# - works for me on low numbers which is all I need for my usecase.

public String convertToRoman(int num)
{    
    //Roman numerals to have <= 3 consecutive characters, the distances between deciaml values conform to this
    int[] decimalValue = { 1000, 900, 500, 400, 100, 90, 50, 40, 10, 9, 5, 4, 1 };
    string[] romanNumeral = { "M", "CM", "D", "CD", "C", "XC", "L", "XL", "X", "IX", "V", "IV", "I" };
    int num_cp = num; // copy the function parameter into num_cp
    String result = "";

    for (var i = 0; i < decimalValue.Length; i = i + 1)
    { //itarate through array of decimal values
        //iterate more to find values not explicitly provided in the decimalValue array
        while (decimalValue[i] <= num_cp)
        {
            result = result + romanNumeral[i];
            num_cp = num_cp - decimalValue[i];
        }
    }
    return result;
}
