Custom Health GUI showing decimals?

I'm trying to create a custom Health GUI to replace the default Health Coregui. Whenever I take damage, it shows decimal numbers after a digit, for example, 70.002944, but this happens only when the Health increases.

local Humanoid = game.Players.LocalPlayer.Character.Humanoid
local currentHealth = Humanoid.Health
Humanoid.HealthChanged:connect(function(health)
	local change = math.abs(currentHealth - health)
	local healthText = script.Parent.Frame.HealthText
	healthText.Text = "HEALTH:"..currentHealth
	currentHealth = health
end)

local Humanoid = game.Players.LocalPlayer.Character.Humanoid
local currentHealth = Humanoid.Health
Humanoid.HealthChanged:connect(function(health)
    local change = math.abs(currentHealth - health)
    local healthText = script.Parent.Frame.HealthText
    rounded = math.floor(currentHealth) -- I rounded currenthealth using math.floor
    healthText.Text = "HEALTH:".. rounded -- and replaced your variable.
    currentHealth = health
end)
