How do I roll my money variable?

Hi I apologize for my bad english.

I have a money variable (you see in the picture)

Let's say I have 3 million dollars. but it says like this 300000000

but I don't want it to write that way

false write 300000000

wrong write 3.000.000.00

WRITE I WANT: 3,000,000

how can I do that?

If my money is 2000 dollars, I want it to write 2,000
