Math.noise only returning one number

Help and Feedback Scripting Support
#1

I am trying to make a simple terrain generator, but whenever I call math. Noise with the position on the noise map, I just get the number 8 returned, no matter what numbers I input into the function.

Here is the code for the module script that I made to handle it

local PN = {}

function PN.Generate(SizeX, SizeZ, Seed)
	for x = 0, SizeX, 1 do
		for z = 0, SizeZ, 1 do
			local noiseScale = 128
			local currentHeight = math.noise(SizeX+Seed, 0.0, SizeZ+Seed)
			print(currentHeight)
			CreatePart(x, z, currentHeight)
		end
	end
end

function CreatePart(XPos, ZPos, YHeight)
	local Part = Instance.new("Part")
	Part.Anchored = true
	Part.Size = Vector3.new(10, YHeight, 10)
	Part.Position = Vector3.new(XPos*10, 0, ZPos*10)
	Part.Parent = workspace.PartStorage
end

return PN

arguments for math.noise need to be a fraction
