Javascript 函数将印度货币数字转换为支持 paise 的单词

还有比这更快的解决方案吗？

在花了一些时间谷歌搜索和玩弄其他人的代码之后，我做了一个快速修复，可重用函数适用于最大 99,99,99,999 的数字。

number2text(1234.56);将返回ONE THOUSAND TWO HUNDRED AND THIRTY-FOUR RUPEE AND FIFTY-SIX PAISE ONLY .

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(Hn) + " THOUSAND"); 
    } 

    if (Dn) 
    { 
        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]; 
        } 
        else 
        { 

            res += tens[tn];
            if (one>0) 
            { 
                res += ("-" + ones[one]); 
            } 
        } 
    }

    if (res=="")
    { 
        res = "zero"; 
    } 
    return res;
