@b264 great start, I suggest to change '﷼‎' to 'SAR' because in Arabic we write from right to left (it looks awkward to me)

@Maroo-b So how do you think is best? I'm unfamiliar with their currency. This is also why I made a class to do this and only this :stuck_out_tongue: expect(Halalas.new(-1234).to_s).to eq 'SAR (12.34)‎'
