Add comma separator to a numbers with 2 decimal points
rory-h
I've managed to make the user input to 2 decimal points: 
Below is my code for two input fields:
$('.ave-daily-accbalance').blur(function(){
var num = parseFloat($(this).val()) || 0;
var cleanNum = num.toFixed(2);
$(this).val(cleanNum);
});
$('.facilitylimit').blur(function(){
var num = parseFloat($(this).val()) || 0;
var cleanNum = num.toFixed(2);
$(this).val(cleanNum);
});
But now I want to seperate the input with comma. So if the user inputs in 500000 - it automatically converts to 500,000.00

You can use Number.prototype.toLocaleString() (documentation) In your case you want to use the second options parameter to specify the number of decimal points you want:
var num = 200000.001231;
var cleanNum = num.toLocaleString('en', {minimumFractionDigits: 2, maximumFractionDigits: 2});
console.log(cleanNum);Note that the options argument does not work on all browser and versions. If compatibility is key, use num.toLocaleString() with no arguments, and trim/append decimals as needed:
var num = 20000.001231;
var cleanNum = num.toLocaleString('en');
var splitNum = cleanNum.split('.');
if (splitNum.length < 2) {
// Need to append .00 if num was an integer
cleanNum = cleanNum + '.00';
} else {
// Append 0 if there was only 1 decimal, otherwise trim
// to 2 decimals
var decimals = splitNum[1];
decimals = decimals.length < 2 ? decimals + '0' : decimals.slice(0, 2);
cleanNum = splitNum[0] + '.' + decimals;
}
console.log(cleanNum);Hope this helps!
