Formatting Number in javascript using decimal

Question

I have following types of values in a, b,c,d.

a= 12345678
b= 12345678.098
c=12345678.1
d=12345678.11

I need to format like,

a = 12,345,678.000
b=  12,345,678.098
c=12,345,678.100
d=12,345,678.110

I already tried tolocaleString() and toFixed(3) method. But I'm not able to works together of both method.

need your suggestion on this.

How can I achieve without using minimumFractionDigits? maximumFractionDigits? — User

var num = 123456789;
console.log(num.toLocaleString(undefined, {minimumFractionDigits: 3, maximumFractionDigits: 3}));

Ref: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Number/toLocaleString

undefined will use user's locale, you might want to specify a custom one.

Updated answer

var number = 12345678;
console.log(parseInt(number*1000).toLocaleString("en-US").replace(/\,([^\,]*)$/,"."+'$1'));

Use Intl.NumberFormat,

var number = 12345678.098;
alert(new Intl.NumberFormat().format(number));

Here's a FIDDLE

You can add the options parameter to get the decimal behaviour (e.g. 12345678 -> '12345678.00'): new Intl.NumberFormat(undefined, { minimumFractionDigits: 3, maximumFractionDigits: 3 }).format(number), or provide this to Number.prototype.toLocaleString() as @BrahmaDev has in his answer
