• javascript
• formatting
• currency
• biginteger

• Convert the number to a String, and add a ma every third character from the right? – Carcigenicate Commented Oct 30, 2016 at 17:00
• Yes. But I need to take care for smaller numbers also – Erik Commented Oct 30, 2016 at 17:02
• Why would my suggestion not work for smaller numbers? – Carcigenicate Commented Oct 30, 2016 at 17:03
• Format numbers in Javascript – jfriend00 Commented Oct 30, 2016 at 17:30

You can use Intl.NumberFormat.prototype.format, String.prototype.slice(), String.prototype.concat()

var number = 2.9364136545300044e+24;
var n = new Intl.NumberFormat().format(number);
var res = n.slice(0, 9).concat(".").concat(n.slice(10, 12));
console.log(res);

As a quick and easy solution you can use number.toLocaleString().

Since, the localString is based on Browser definition different users may get a different results. However, you can force a specific location to always get the same format. Ex: toLocaleString('en-GB', { timeZone: 'UTC' })
