Is your feature request related to a problem? Please describe.
I'm frustrated when I read a number like 100000000 without thousand separators, make us hard to see what number is displayed.

Describe the solution you'd like
Having thousand separators will automatically ease your job when you need to read 100000000. It is clearly a hundred millions when you have thousand separators in that number 100,000,000.

Describe alternatives you've considered
The solution will accept number input, then add comma for every multiplication of thousand, and return it as a string (since it has commas in the number).
