[SOLVED] Displaying a number in Indian format using Javascript

Displaying a number in Indian format using Javascript

I have the following code to display in Indian numbering system.

 var x=125465778;
 var res= x.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ",");

Am getting this output :125,465,778.

I need output like this: 12,54,65,778.

Please help me to sort out this problem .

Solution

For Integers:

    var x=12345678;
    x=x.toString();
    var lastThree = x.substring(x.length-3);
    var otherNumbers = x.substring(0,x.length-3);
    if(otherNumbers != '')
        lastThree = ',' + lastThree;
    var res = otherNumbers.replace(/\B(?=(\d{2})+(?!\d))/g, ",") + lastThree;
    alert(res);

For float:

    var x=12345652457.557;
    x=x.toString();
    var afterPoint = '';
    if(x.indexOf('.') > 0)
       afterPoint = x.substring(x.indexOf('.'),x.length);
    x = Math.floor(x);
    x=x.toString();
    var lastThree = x.substring(x.length-3);
    var otherNumbers = x.substring(0,x.length-3);
    if(otherNumbers != '')
        lastThree = ',' + lastThree;
    var res = otherNumbers.replace(/\B(?=(\d{2})+(?!\d))/g, ",") + lastThree + afterPoint;
    
    alert(res);
