Attempting to perform arithmetic on extremely large numbers?

Hi! So I have a simulator with extremely large numbers and when it gets to a certain number, it just won’t increase it any more. How can I handle this?

increaseClickRE.OnServerEvent:Connect(function(plr, baseAmount)
	if plr:IsInGroup(9487345) then
		print(1 * math.round(((((baseAmount * plr.ClickMultiplier.Value) * plr.PetMultiplier.Value) * plr:FindFirstChild("Multiplier").Value)) * 2) * plr:WaitForChild("RankMultiplier").Value)
		plr:WaitForChild("leaderstats"):WaitForChild("Total Crowns").Value += 1 * math.round(((((baseAmount * plr.ClickMultiplier.Value) * plr.PetMultiplier.Value) * plr:FindFirstChild("Multiplier").Value)) * 2) * plr:WaitForChild("RankMultiplier").Value
		
		plr:WaitForChild("leaderstats"):WaitForChild("Crowns").Value +=  1 * math.round(((((baseAmount * plr.ClickMultiplier.Value) * plr.PetMultiplier.Value) * plr:FindFirstChild("Multiplier").Value)) * 2) * plr:WaitForChild("RankMultiplier").Value
	else
		plr:WaitForChild("leaderstats"):WaitForChild("Total Crowns").Value += 1 * math.round(((baseAmount * plr.ClickMultiplier.Value) * plr.PetMultiplier.Value) * plr:FindFirstChild("Multiplier").Value) * plr:WaitForChild("RankMultiplier").Value
		plr:WaitForChild("leaderstats"):WaitForChild("Crowns").Value += 1 * math.round(((baseAmount * plr.ClickMultiplier.Value) * plr.PetMultiplier.Value) * plr:FindFirstChild("Multiplier").Value) * plr:WaitForChild("RankMultiplier").Value
	end
end)

NOTE: The print on line 3 prints correctly. It is just performing + - * or / on it that it causing the problem

The kind of numbers I’m dealing with is like 10e20

#3

The max number roblox can work with is 2^63 - 1, or a signed 64-bit integer. This is equivalent to 9.22337204e18. 10e20 is much larger than this and isn’t supported in lua. Counting higher than this causes an integer overflow error

My mistake, I was specifying int64.

#4

So, there is no way to counter this?

#5

The max number in lua is 1.7 × 10^308 which your number falls into, you’re not specifying int64 are you?

#6

All the value used are number values not int values if that’s what you mean

#7

If you are using the actual NumberValue class, then this is what the docs say:

A NumberValue is an object whose purpose is to store a single Lua number, defined to be double-precision floating point number, or more commonly known as a double . This stores a number in 64 bits (8 bytes) using the IEEE 754 representation (1 sign bit, 11 exponent bits and 52 fractional bits). The maximum numerical value that may be stored is 2^53, or 9,007,199,254,740,992, and the minimum is -9,007,199,254,740,992. It stores up to 15 digits of precision.

Oh I see, the max value is 2^53.

#9

In this case, what should I do to go over the limit for number values

#10

maybe add a second value convert it to a string? and make a system that does the addition algorthm eg(100
50 +
