JavaScript में भारतीय मुद्रा संख्या को शब्दों में बदलना (पैसे सहित)

हमें एक JavaScript फ़ंक्शन लिखना है जो 2 अंकों की सटीकता तक की एक फ्लोटिंग-पॉइंट संख्या लेता है।

फ़ंक्शन को उस संख्या को भारतीय मुद्रा पाठ में बदलना चाहिए।

उदाहरण के लिए -

यदि इनपुट संख्या है -

const num = 12500

तो आउटपुट होना चाहिए -

const output = 'Twelve Thousand Five Hundred';

उदाहरण

निम्नलिखित कोड देखें:

const num = 12500;

const wordify = (num) => {
  const single = ["Zero", "One", "Two", "Three", "Four", "Five", "Six", "Seven", "Eight", "Nine"];
  const double = ["Ten", "Eleven", "Twelve", "Thirteen", "Fourteen", "Fifteen", "Sixteen", "Seventeen", "Eighteen", "Nineteen"];
  const tens = ["", "Ten", "Twenty", "Thirty", "Forty", "Fifty", "Sixty", "Seventy", "Eighty", "Ninety"];
  
  const formatTenth = (digit, prev) => {
    return 0 == digit ? "" : " " + (1 == digit ? double[prev] : tens[digit]);
  };
  
  const formatOther = (digit, next, denom) => {
    return (0 != digit && 1 != next ? " " + single[digit] : "") + (0 != next || digit > 0 ? " " + denom : "");
  };
  
  let res = "";
  let index = 0;
  let digit = 0;
  let next = 0;
  let words = [];
  
  if (num += "", isNaN(parseInt(num))) {
    res = "";
  } else if (parseInt(num) > 0 && num.length <= 10) {
    for (index = num.length - 1; index >= 0; index--) switch (digit = num[index] - 0, next = index > 0 ? num[index - 1] - 0 : 0, num.length - index - 1) {
      case 0:
        words.push(formatOther(digit, next, ""));
        break;
      case 1:
        words.push(formatTenth(digit, num[index + 1]));
        break;
      case 2:
        words.push(0 != digit ? " " + single[digit] + " Hundred" + (0 != num[index + 1] && 0 != num[index + 2] ? " and" : "") : "");
        break;
      case 3:
        words.push(formatOther(digit, next, "Thousand"));
        break;
      case 4:
        words.push(formatTenth(digit, num[index + 1]));
        break;
      case 5:
        words.push(formatOther(digit, next, "Lakh"));
        break;
      case 6:
        words.push(formatTenth(digit, num[index + 1]));
        break;
      case 7:
        words.push(formatOther(digit, next, "Crore"));
        break;
      case 8:
        words.push(formatTenth(digit, num[index + 1]));
        break;
      case 9:
        words.push(0 != digit ? " " + single[digit] + " Hundred" + (0 != num[index + 1] || 0 != num[index + 2] ? " and" : " Crore") : "");
    }
    res = words.reverse().join("")
  } else res = "";
  return res;
};

console.log(wordify(num));

आउटपुट

कंसोल पर निम्नलिखित आउटपुट प्राप्त होगा:

Twelve Thousand Five Hundred
