convert number to roman numerals javascript

Comment

function convertToRoman(num) {
  var roman = "";
  var romanNumeral = ["M", "CM", "D", "CD", "C", "XC", "L", "XL", "X", "IX", "V", "IV", "I"];
  var numbers = [1000, 900, 500, 400, 100, 90, 50, 40, 10, 9, 5, 4, 1];

  for (var i = 0; i < numbers.length; i++) {
    while (num >= numbers[i]) {
      roman += romanNumeral[i];
      num -= numbers[i];
    }
  }

  return roman;
}

Explanation:

The function takes in a single parameter, "num", which is the number to be converted to Roman numerals.

The variable "roman" is initialized as an empty string. This variable will be used to store the Roman numeral representation of "num".

The variable "romanNumeral" is an array of strings, containing the Roman numerals in the order they are to be used in the conversion.

The variable "numbers" is an array of integers, containing the decimal equivalents of the Roman numerals in "romanNumeral"

The function uses a for loop to iterate through the "numbers" array.

Within the for loop, the function uses a while loop to check if the current number in "numbers" is less than or equal to the value of "num". If this is the case, the corresponding Roman numeral from "romanNumeral" is added to "roman", and the value of "num" is reduced by the current number in "numbers".

Once the for loop completes execution, the function returns the final value of "roman", which is the Roman numeral representation of the input number "num".
