Convert Numbers into Words Using JavaScript

Hello friends,

Today in Developer's Blog, I am going to tell you the way by which we will be able to easily convert Numbers into Words using JavaScript.

First of all you will have to create a JavaScript file (.js) using below code :

var th = ['','thousand','million', 'billion','trillion'];

var dg = ['zero','one','two','three','four', 'five','six','seven','eight','nine']; 

var tn = ['ten','eleven','twelve','thirteen', 'fourteen','fifteen','sixteen', 'seventeen','eighteen','nineteen'];

var tw = ['twenty','thirty','forty','fifty', 'sixty','seventy','eighty','ninety']; 

function toWords(s)

{  

    s = s.toString(); 

    s = s.replace(/[\, ]/g,''); 

    if (s != parseFloat(s)) return 'not a number'; 

    var x = s.indexOf('.'); 

    if (x == -1) x = s.length; 

    if (x > 15) return 'too big'; 

    var n = s.split(''); 

    var str = ''; 

    var sk = 0; 

    for (var i=0; i < x; i++) 

    {

        if ((x-i)%3==2) 

        {

            if (n[i] == '1') 

            {

                str += tn[Number(n[i+1])] + ' '; 

                i++; 

                sk=1;

            }

            else if (n[i]!=0) 

            {

                str += tw[n[i]-2] + ' ';

                sk=1;

            }

        }

        else if (n[i]!=0) 

        {

            str += dg[n[i]] +' '; 

            if ((x-i)%3==0) str += 'hundred ';

            sk=1;

        }

        if ((x-i)%3==1)

        {

            if (sk) str += th[(x-i-1)/3] + ' ';

            sk=0;

        }

    }

    if (x != s.length)

    {

        var y = s.length; 

        str += 'point '; 

        for (var i=x+1; i<y; i++) str += dg[n[i]] +' ';

    }

    return str.replace(/\s+/g,' ');

}

So by this you will be able to Convert Number into Words Using JavaScript.

I hope this will help you and you will like it.
