Numbers not rounding right

Hey devs,
I havent been able to figure out this problem even though its something so easy, The numbers always are being rounded to supper long decimals and I cant figure it out! Any ideas on how to fix this?

local function animateCount(label, start, finish)
	local diff = finish - start
	local duration = math.clamp(math.abs(diff) / 50, 0.2, 1)
	local steps = 30
	for i = 1, steps do
		local alpha = i / steps
		local current = start + diff * alpha
		if math.abs(finish) >= 1000 then
			label.Text = Formatter.checkzeros(current, 1)
		else
			label.Text = string.format("%.1f", current)
		end
		task.wait(duration / steps)
	end
	if math.abs(finish) >= 1000 then
		label.Text = Formatter.checkzeros(finish, 1)
	else
		label.Text = tostring(finish)
	end
end

You can round the number before you convert it to string. Multiply by your desired precision (e.g. 100 for two digits), math.round() and then divide by 100. This will output 45.42.

print(math.round(45.424623452345 * 100) / 100) -- 45.42

There’s a way to do it with string.format() as well.

print(string.format("%.2f",45.424623452345)) -- 45.42

So how would I incorporate that into my script so it works?

I think you want it each of the times you set. the label.Text property. There’s already a round to 1 digit of precision on the line in the steps loop. You can add that to the line outside of the loop as well.

I’m not sure what Formatter does. If it’s a library then it might have a function that handles precision. If the output of Formatter.checkzeros() is good then you might just need to use that on each of the labels. The conditional wouldnt’ be needed if this works.

Floating-point math isn’t exact, but you can force clean rounding by quantizing current before displaying..

local function animateCount(label, start, finish)
	local diff = finish - start
	local duration = math.clamp(math.abs(diff) / 50, 0.2, 1)
	local steps = 30
	for i = 1, steps do
		local alpha = i / steps
		local current = math.floor((start + diff * alpha) * 10 + 0.5) / 10
		if math.abs(finish) >= 1000 then
			label.Text = Formatter.checkzeros(current, 1)
		else
			label.Text = string.format("%.1f", current)
		end
		task.wait(duration / steps)
	end
	if math.abs(finish) >= 1000 then
		label.Text = Formatter.checkzeros(finish, 1)
	else
		label.Text = tostring(finish)
	end
end

This rounds to one decimal consistently before formatting.

local current = math.floor((start + diff * alpha) * 10 + 0.5) / 10
Client Test Script 
local label = Instance.new("TextLabel")
label.Size = UDim2.new(0,200,0,50)
label.Position = UDim2.new(0.5,-100,0.5,-25)
label.TextScaled = true
label.Parent = game.Players.LocalPlayer:WaitForChild("PlayerGui")

local Formatter = {}
function Formatter.checkzeros(num, dec)
	return string.format("%."..dec.."f", num)
end

local function animateCount(label, start, finish)
	local diff = finish - start
	local duration = math.clamp(math.abs(diff) / 50, 0.2, 1)
	local steps = 30
	for i = 1, steps do
		local alpha = i / steps
		local current = math.floor((start + diff * alpha) * 10 + 0.5) / 10
		print("Current:", current)
		if math.abs(finish) >= 1000 then
			label.Text = Formatter.checkzeros(current, 1)
		else
			label.Text = string.format("%.1f", current)
		end
		task.wait(duration / steps)
	end
	if math.abs(finish) >= 1000 then
		label.Text = Formatter.checkzeros(finish, 1)
	else
		label.Text = tostring(finish)
	end
end

print("Starting animation")
animateCount(label, 0, 1234)
print("Done")

This is the full script Im not sure why its still happening

		local alpha = i / steps
		local current = math.floor((start + diff * alpha) * 10 + 0.5) / 10
		if math.abs(finish) >= 1000 then
			label.Text = Formatter.checkzeros(current, 1)
		else
			label.Text = string.format("%.1f", current)
		end
		task.wait(duration / steps)

If the issue happens specifically with numbers smaller than 1000 then it may be because of your last tostring(finish) case. It doesn’t round the result like the other ones do. This is assuming Formatter.checkzeros rounds results because we don’t have code for that.

The issue seems to originate in the required module:

function Formatter.checkzeros(num, dec)
	num = math.floor(num * 10^dec + 0.5) / 10^dec
	return string.format("%."..dec.."f", num)
end

This should get that rolling.

Basically I’m just rounding the numbers first, then formatting them, so the text always shows clean, exact decimals instead of floating-point noise.
