Problem with adding numbers

[R05HX (Rosh)]

Hello devs!

I’m making Rebirth system and when the numbers is adding in GUI the text is: x1.100000000001

but I want to add 0.1 to energy and 0.05 to speed

Here is local script:

local RebirthFrame = script.Parent.Rebirth
local EnergyValue = RebirthFrame.Value1
local SpeedValue = RebirthFrame.Value2
local RebirthButton = RebirthFrame.Rebirth
local Require = 10
local EnergyGive = .1
local TrainingGive = .05

spawn(function()
	while wait() do
		EnergyValue.Text = "x⚡"..plr.Rebirth.EnergyR.Value + EnergyGive.." Energy"
		SpeedValue.Text = "x👟"..plr.Rebirth.SpeedR.Value + TrainingGive.." Training"
	end
end)

RebirthButton.MouseButton1Click:Connect(function()
	if plr.leaderstats.Energy.Value >= Require then
		GUIRemotes.Rebirth:FireServer(Require, TrainingGive, EnergyGive)
	end
end)

Here is Script:

--[[Rebirth]]--
local RebirthRemote = GUIRemotes.Rebirth

RebirthRemote.OnServerEvent:Connect(function(plr, Require, SpeedR, EnergyR)
	if plr.leaderstats.Energy.Value >= Require then
		plr.leaderstats.Energy.Value = 0
		plr.leaderstats.Speed.Value = 10
		plr.Rebirth.SpeedR.Value += SpeedR
		plr.Rebirth.EnergyR.Value += EnergyR
	end
end)

You could use math.floor();

print(math.floor(2.32583847473 * 10) / 10)

The script above would print “2.3”

I do recommend looking into remote security right now anyone can change their rebirth speed and energy to whatever they want.

Roblox made a change to tostring recently, which is also called when you use the concatenation operator.

Behavior change: tostring() will start returning shortest precise decimal representation of numbers

TL;DR We’re going to be making a change to tostring() printing numbers that may result in printing longer output with decimal digits that you haven’t seen before. If you were relying on number-to-string conversions producing up to a given number of decimals, you should probably use string.format("%.1f", v) instead or equivalent (this expression prints up to one decimal digit). If you want to use the exact same formatting method that we’ve used before as part of tostring, you can use string.for…

I’m not 100% sure but It could be this.

This is called a floating-point number, which is caused by how computers do math. Using math.floor like @UhTrue said might work in this case, but it is also important to remember that math.floor will always round down. So if it were to ever go the other way, for example “1.29999999999999”, you would want to round to the nearest whole number, not always to the nearest integer that is smaller than that number. Since you’re using 2 decimal place as well, you need to multiply the number first by 100, so you are working with whole numbers, since rounding will not account for decimals.

local energyValue = plr.Rebirth.EnergyR.Value + EnergyGive
energyValue = math.round(energyValue * 100)/100

Alternatively, you could also just limit the number of characters that the text label shows using string.sub(). However, it may still count some 0’s behind the decimal, and if that is the case you can turn it back into a number, so it will ignore that.

local energyValue = tostring(plr.Rebirth.EnergyR.Value + EnergyGive)
string.sub(energyValue, 1, 4)

Forgot ab that, thanks for helping the op
