How to make the camera stop spinning?

[Anibration]

The code below makes it so when you rotate the camera it spins smoothly. The only problem is that the camera keeps on spinning and it never stops. I want to add something in the script so the camera decelerates once the camera has stopped accelerating. In other words: I want the camera to slowly stop spinning instead of it spinning forever. How do I achieve this? The code below is in a local script in StarterGui.

local run = game:GetService'RunService'
local uis = game:GetService'UserInputService'

local cam = workspace.Camera
local plr = game.Players.LocalPlayer
local mouse = plr:GetMouse()

local mult = 180/math.pi
local clamp = math.clamp

local current = Vector2.zero
local targetX, targetY = 0, 0

local speed = 0.5 -- Set the speed of the animation
local sensitivity = 1 -- Set the sensitivity of the rotation

uis.MouseDeltaSensitivity = 0.01
cam.CameraType = Enum.CameraType.Custom

run:BindToRenderStep("SmoothCam", Enum.RenderPriority.Camera.Value-1, function(dt)
	local delta = uis:GetMouseDelta()*sensitivity*100
	targetX += delta.X
	targetY = clamp(targetY+delta.Y,-90,90)
	current = current:Lerp(Vector2.new(targetX,targetY), dt*speed)
	cam.CFrame = CFrame.fromOrientation(-current.Y/mult,-current.X/mult,0)
end)

I discovered this equation though this video a while ago. I’m not entirely sure if it’s the effect you need but it allows for some dampening to occur as a value nears its target.

local goal --The goal value to be reached

currentPositon = currentPositon + (goal-currentPositon) * math.min(dt*1,1) 

--Multiply dt to effect speed

I added that equation into the script and it works! The camera now gradually slows down to a stop. Thank you .
