Number on keyup add comma in INR standard

I am trying to remove text after numbers typed and add decimal

I have multiple input type="text" where on keypress I am adding a comma in INR (Indian Rupee) standard but when I type more than three numbers the entire value is removed and '0' is added. Also my code is not allowing the decimal .00 number as it should. What am I doing wrong?

JS Fiddle

HTML:

<input name="txtMSExMarCardFee" type="number" id="txtMSExMarCardFee" class="Stylednumber">
<input name="txtMSExMarCardFee1" type="number" id="txtMSExMarCardFee1" class="Stylednumber">
<input name="txtMSExMarCardFee2" type="number" id="txtMSExMarCardFee2" class="Stylednumber">

JS:

$('input.Stylednumber').keyup(function(){
    var x=$(this).val();
    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;


    $(this).val(res );

});

Try using this:

$('input.Stylednumber').keyup(function(){
  var t = $(this), v = t.val();
  if(!v.match(/\.\d{2}$/)){
    v += '.00';
  }
  v = parseFloat(v.replace(/,/g, ''));
  if(!v){ // was not a number
    t.val('0.00');
    return false;
  }
  v = v.toFixed(2);
  if(v.length > 6){ 
    t.val(v.slice(0, -6).replace(/(/d{3})/, '$1,')+v.slice(-6));
  }
  else{
    t.val(v);
  }
});

This requires that you cleanup the input before you pass it to through the regex

String.prototype.replaceAll = function(search, replacement) {
  var target = this;
  return target.replace(new RegExp(search, 'g'), replacement);
};

$('input.Stylednumber').keyup(function() {
  var input = $(this).val().replaceAll(',', '');
  if (input.length < 1)
    $(this).val('0.00');
  else {
    var val = parseFloat(input);
    var formatted = inrFormat(input);
    if (formatted.indexOf('.') > 0) {
      var split = formatted.split('.');
      formatted = split[0] + '.' + split[1].substring(0, 2);
    }
    $(this).val(formatted);
  }
});

function inrFormat(val) {
  var x = val;
  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;
  return res;
}
