How to insert a comma in a string before every 3 numbers

Help and Feedback Scripting Support
#1

I’m creating a money system where when a player joins an IntValue is inserted into the player and a gui automatically updates every 5 seconds as the intValue.Value, I want to make it so that if a player had their intvalue set to 5000 in the gui it would format as 5,000. Normally I would go to the wiki for information before coming here, but I cannot understand basically anything the wiki had to say. Would love to know.

Are you sure baout that? That would be expensive. Why not use the GetPropertyChnagedSignal?

Anyways, have you thought about how much currency a player can accumulate?

--Local script, under the gui
local name = game.Players.LocalPlayer.Name
local IntValue = [The IntValue folder]:FindFirstChild(name) 
IntValue:GetPropertyChnagedSignal("Value"):Connect(function() 
	script.Parent.Text = IntValue.Value
end)

Here’s a useful webpage for formatting numbers:
http://lua-users.org/wiki/FormattingNumbers

function comma_value(amount)
  local formatted = amount
  while true do  
    formatted, k = string.gsub(formatted, "^(-?%d+)(%d%d%d)", '%1,%2')
    if (k==0) then
      break
    end
  end
  return formatted
end

Micro-optimized 'cause I was bored:

function comma_value(amount)
	local formatted, k = amount, nil
	local a, b = "^(-?%d+)(%d%d%d)", '%1,%2'
	repeat
		formatted, k = string.gsub(formatted, a, b)
	until (k == 0)
	return formatted
end

I appreciate your response but I found a neat module by @gillern that formats numbers and it works really nicely
