[SOLVED] How can you make for example 1.298018197102000063e+42 a normal number?

I have a problem, I tried to make a K,M,B system, but there is a problem, roblox changes big numbers to numbers like this one --> 1.298018197102000063e+42. But I convert it to a string, so my script sees the number like 1.2 --> wich will result in something like 1K.

This is very annoying, so my question is, is there any way to change them back in a script? (I tried searching for it but I don't know how it's called if there is a name for it).

The script works fine when roblox didn't change the value

(This is my script)

return module

EDIT: Thanks to MCAndRobloxUnited I found the solution:

Cannot copy the solution, but go take a look at string.format, you can find it there --> Works great

IF ANYONE HAS TROUBLE WITH THIS, YOU CAN EITHER REPLY TO THIS OR SEND ME A MESSAGE TO ME (/MY ROBLOX PROFILE)

1.298018197102000063e+42 is actually 1.298018197102000063 * 10^42. Just for easier maths.

Hope this helps!

I know that you said this question was solved, but I thought I would post an interesting solution I found for people who need to know this kind of thing and find your question. Here is how I overcame this problem:

	money.Changed:Connect(function()
		
		local amountLableFound = false
		
		for i = 3, 12, 3 do 
		
			if money.Value >= (10 ^ i) and money.Value < (10 ^ (i + 3)) then
				
				amountLableFound = true
				
				local uncheckedMVariable = (math.floor(money.Value / (10 ^ (i - 2))) / 100)	
				local strMVariable = tostring(uncheckedMVariable)
				local decimalCheck = string.find(strMVariable, "%.")
				local mVariable
				
				if decimalCheck and decimalCheck ~= 4 then
					
					mVariable = string.sub(strMVariable, 1, 4)
						
				else
						
					mVariable = string.sub(strMVariable, 1, 3)
						
				end

				if money.Value > (uncheckedMVariable * (10 ^ (i - 2)) * 100) then
					
					if money.Value >= (10 ^ 12) then
						
						cash.Value = mVariable.."T+"
						
					elseif money.Value >= (10 ^ 9) then
						
						cash.Value = mVariable.."B+"
						
					elseif money.Value >= (10 ^ 6) then
						
						cash.Value = mVariable.."M+"
						
					elseif money.Value >= (10 ^ 3) then	
						
						cash.Value = mVariable.."K+"
						
					end
					
				else
					
					if money.Value >= (10 ^ 12) then
						
						cash.Value = mVariable.."T"
						
					elseif money.Value >= (10 ^ 9) then
						
						cash.Value = mVariable.."B"
						
					elseif money.Value >= (10 ^ 6) then
						
						cash.Value = mVariable.."M"
						
					elseif money.Value >= (10 ^ 3) then	
						
						cash.Value = mVariable.."K"
						
					end
	
				end	
				
			end
			
		end
		
		if not amountLableFound then
		
			cash.Value = math.floor(money.Value)
						
		end
		
	end)

Note: cash is a string value and money is a number value. cash is what displays on the leaderboard. If you need larger amounts just add on to the length of the for loop and add on an elseif. I hope you find this helpful(to anyone who finds this). I also hope that you find this interesting @RedcommanderV2.
