JavaScript numbers to Words-第3页回答

I'm trying to convert numbers into english words, for example 1234 would become: "one thousand two hundred thirty four".

My Tactic goes like this:

Separate the digits to three and put them on Array (finlOutPut), from right to left.
Convert each group (each cell in the finlOutPut array) of three digits to a word (this what the triConvert function does). If all the three digits are zero convert them to "dontAddBigSuffix"
From Right to left, add thousand, million, billion, etc. If the finlOutPut cell equals "dontAddBigSufix" (because it was only zeroes), don't add the word and set the cell to " " (nothing).

It seems to work pretty well, but I've got some problems with numbers like 190000009, converted to: "one hundred ninety million". Somehow it "forgets" the last numbers when there are a few zeros.

What did I do wrong? Where is the bug? Why does it not work perfectly?

I've modified the posting from Šime Vidas - http://jsfiddle.net/j5kdG/ To include dollars, cents, commas and "and" in the appropriate places. There's an optional ending if it requires "zero cents" or no mention of cents if 0.

This function structure did my head in a bit but I learned heaps. Thanks Sime.

Someone might find a better way of processing this.

Code:

var str='';
var str2='';
var str3 =[];

function convertNum(inp,end){
    str2='';
    str3 = [];
    var NUMBER2TEXT = {
    ones: ['', 'one', 'two', 'three', 'four', 'five', 'six', 'seven', 'eight', 'nine', 'ten', 'eleven', 'twelve', 'thirteen', 'fourteen', 'fifteen', 'sixteen', 'seventeen', 'eighteen', 'nineteen'],
    tens: ['', '', 'twenty', 'thirty', 'forty', 'fifty', 'sixty', 'seventy', 'eighty', 'ninety'],
    sep: ['', ' thousand', ' million', ' billion', ' trillion', ' quadrillion', ' quintillion', ' sextillion']
};
(function( ones, tens, sep ) {
   var vals = inp.split("."),val,pos,postsep=' ';
   for (p in vals){
      val = vals[p], arr = [], str = '', i = 0;
      if ( val.length === 0 ) {return 'No value';}
      val = parseInt( (p==1 && val.length===1 )?val*10:val, 10 );
      if ( isNaN( val ) || p>=2) {return 'Invalid value'; }
      while ( val ) {
        arr.push( val % 1000 );
        val = parseInt( val / 1000, 10 );   
      }
      pos = arr.length;
      function trimx (strx) {
                return strx.replace(/^\s\s*/, '').replace(/\s\s*$/, '');
            }

                    if (str3[s-2][1] === str3[s-1][0]){
                        str = str.replace(str3[s-2][1],'')
                    }

        str = (function( a ) {
            var x = Math.floor( a / 100 ),

I know this problem had solved 3 years ago. I am posting this SPECIALLY FOR INDIAN DEVELOPERS

After spending some time in googling and playing with others code i made a quick fix and reusable function works well for numbers upto 99,99,99,999. use : number2text(1234.56); will return ONE THOUSAND TWO HUNDRED AND THIRTY-FOUR RUPEE AND FIFTY-SIX PAISE ONLY . enjoy !

function number2text(value) {
    var fraction = Math.round(frac(value)*100);
    var f_text  = "";

    if(fraction > 0) {
        f_text = "AND "+convert_number(fraction)+" PAISE";
    }

    return convert_number(value)+" RUPEE "+f_text+" ONLY";
}

function frac(f) {
    return f % 1;
}

function convert_number(number)
{
    if ((number < 0) || (number > 999999999)) 
    { 
        return "NUMBER OUT OF RANGE!";
    }
    var Gn = Math.floor(number / 10000000);  /* Crore */ 
    number -= Gn * 10000000; 
    var kn = Math.floor(number / 100000);     /* lakhs */ 
    number -= kn * 100000; 
    var Hn = Math.floor(number / 1000);      /* thousand */ 
    number -= Hn * 1000; 
    var Dn = Math.floor(number / 100);       /* Tens (deca) */ 
    number = number % 100;               /* Ones */ 
    var tn= Math.floor(number / 10); 
    var one=Math.floor(number % 10); 
    var res = ""; 

    if (Gn>0) 
    { 
        res += (convert_number(Gn) + " CRORE"); 
    } 
    if (kn>0) 
    { 
            res += (((res=="") ? "" : " ") + 
            convert_number(kn) + " LAKH"); 
    } 
    if (Hn>0) 
    {

    { 
        res += (((res=="") ? "" : " ") + 
            convert_number(Dn) + " HUNDRED"); 
    } 


    var ones = Array("", "ONE", "TWO", "THREE", "FOUR", "FIVE", "SIX","SEVEN", "EIGHT", "NINE", "TEN", "ELEVEN", "TWELVE", "THIRTEEN","FOURTEEN", "FIFTEEN", "SIXTEEN", "SEVENTEEN", "EIGHTEEN","NINETEEN"); 
var tens = Array("", "", "TWENTY", "THIRTY", "FOURTY", "FIFTY", "SIXTY","SEVENTY", "EIGHTY", "NINETY"); 

    if (tn>0 || one>0) 
    { 
        if (!(res=="")) 
        { 
            res += " AND "; 
        } 
        if (tn < 2) 
        { 
            res += ones[tn * 10 + one];

6楼-- · 2019-01-01 01:43

I think, I have solution that's simpler and easier to understand; it goes by slicing the number, it works up to 99 lakhs crore.

function convert_to_word(num, ignore_ten_plus_check) {

var ones = [];
var tens = [];
var ten_plus = [];
ones["1"] = "one";
ones["2"] = "two";
ones["3"] = "three";
ones["4"] = "four";
ones["5"] = "five";
ones["6"] = "six";
ones["7"] = "seven";
ones["8"] = "eight";
ones["9"] = "nine";

ten_plus["10"] = "ten";
ten_plus["11"] = "eleven";
ten_plus["12"] = "twelve";
ten_plus["13"] = "thirteen";
ten_plus["14"] = "fourteen";
ten_plus["15"] = "fifteen";
ten_plus["16"] = "sixteen";
ten_plus["17"] = "seventeen";
ten_plus["18"] = "eighteen";
ten_plus["19"] = "nineteen";

tens["1"] = "ten";
tens["2"] = "twenty";
tens["3"] = "thirty";
tens["4"] = "fourty";
tens["5"] = "fifty";
tens["6"] = "sixty";
tens["7"] = "seventy";
tens["8"] = "eighty";
tens["9"] = "ninety";   

    var len = num.length;

    if(ignore_ten_plus_check != true && len >= 2) {
        var ten_pos = num.slice(len - 2, len - 1);
        if(ten_pos == "1") {
            return ten_plus[num.slice(len - 2, len)];
        } else if(ten_pos != 0) {
            return tens[num.slice(len - 2, len - 1)] + " " + ones[num.slice(len - 1, len)];
        }
    }

    return ones[num.slice(len - 1, len)];

}

function get_rupees_in_words(str, recursive_call_count) {
  if(recursive_call_count > 1) {
        return "conversion is not feasible";
    }
    var len = str.length;
    var words = convert_to_word(str, false);
    if(len == 2 || len == 1) {
    if(recursive_call_count == 0) {
        words = words +" rupees";
    }
        return words;
    }
    if(recursive_call_count == 0) {
        words = " and " + words +" rupees";
    }



var hundred = convert_to_word(str.slice(0, len-2), true);
  words = hundred != undefined ? hundred + " hundred " + words : words;
    if(len == 3) {
        return words;
    }

var thousand = convert_to_word(str.slice(0, len-3), false);
words = thousand != undefined ? thousand  + " thousand " + words : words;
if(len <= 5) {
    return words;
}

var lakh = convert_to_word(str.slice(0, len-5), false);
words =  lakh != undefined ? lakh + " lakh " + words : words;
if(len <= 7) {
    return words;
}

recursive_call_count = recursive_call_count + 1;
return get_rupees_in_words(str.slice(0, len-7), recursive_call_count) + " crore " + words;
}

I think this will help you

    aTens = [ "Twenty", "Thirty", "Forty", "Fifty", "Sixty", "Seventy","Eighty", "Ninety"];

    aOnes = [ "Zero", "One", "Two", "Three", "Four", "Five", "Six", "Seven", "Eight", "Nine", "Ten", "Eleven", "Twelve", "Thirteen", "Fourteen", "Fifteen", "Sixteen", "Seventeen", "Eighteen", "Nineteen" ];
    var aUnits = "Thousand";
    function convertnumbertostring(){
       var num=prompt('','enter the number');
       var j=6;
       if(num.length<j){
       var y = ConvertToWords(num);
       alert(y);
       }else{
          alert('Enter the number of 5 letters')
       }
    };
    function ConvertToHundreds(num)
    {
       var cNum, nNum;
       var cWords = "";
       if (num > 99) {
          /* Hundreds. */
          cNum = String(num);
          nNum = Number(cNum.charAt(0));
          cWords += aOnes[nNum] + " Hundred";
          num %= 100;
          if (num > 0){
             cWords += " and "
          }
       }

       if (num > 19) {
          /* Tens. */
          cNum = String(num);
          nNum = Number(cNum.charAt(0));
          cWords += aTens[nNum - 2];
          num %= 10;
          if (num > 0){
             cWords += "-";
          }
       }
       if (num > 0) {
          /* Ones and teens. */
          nNum = Math.floor(num);
          cWords += aOnes[nNum];
       }
       return(cWords);

    }
    function ConvertToWords(num)
    {
       var cWords;
       for (var i = 0; num > 0; i++) { 
           if (num % 1000 > 0) {
              if (i != 0){
                 cWords = ConvertToHundreds(num) + " " + aUnits + " " + cWords;
              }else{
                 cWords = ConvertToHundreds(num) + " ";
              }        
           }
           num = (num / 1000);
       }
         return(cWords);
    }
