Angular2 :: Javascript :: Currency formatting :: PKR 12,34,56,789/-

Question

Whereas usually a large currency value like USD 123456789 is formatted as USD 123,456,789, here in Pakistan, such a number is formatted as Rs. 12,34,56,789/- (last 3 digits grouped, then every 2 digits grouped together, the entire string followed by a /-.

Is it possible to use the default Angular Currency pipe to achieve this? If not, what's the correct regex that I can use to achieve this formatting in my custom pipe's transform method?

Searching more around SO, I found this post which addresses the same problem:

Displaying a number in Indian format using Javascript

The relevant code snippet is this:

let amount = value.toString();
var lastThree = amount.substring(amount.length - 3);
var otherNumbers = amount.substring(0, amount.length - 3);
if(otherNumbers != '') lastThree = ',' + lastThree;
var result = otherNumbers.replace(/\B(?=(\d{2})+(?!\d))/g, ",") + lastThree;

This works fine for my case as well.. =)
