  1. What do you want to achieve? Keep it simple and clear!
    Topic says all about what i need
  2. What is the issue? Include screenshots / videos if possible!
    I have no idea about it

    I looked few topics, though nothing helps

Function:

local function Suffix(Number, Precision)
	local Suffixes = {
		"", " K"," M", " B", " T",
		" Qd", " Qn", " Sx", " Sp",
		" Oc", " No", " De", " Un",
		" Tr", " Qud", " Qun", " Sxd",
		" Spd", " Ocd", " Nod", " Vg",
		" UVg"," DVg"," TVg"," QdVg",
		" QnVg"," SxVg"," SpVg"," OcVg",
		" NoVg"," Tg"," UTg"," DTg"," TTg",

		" QdNg"," QnNg"," SxNg"," SpNg"," OcNg"," NoNg"
	}

	local Index = math.floor(math.log10(Number) / 3)
	if Index < 0 then
		Index = 0
	end
	local Suffix = Suffixes[Index + 1]

	Number = Number / (10 ^ (3 * Index))
	Number = tostring(math.floor(Number * 10 ^ Precision) / 10 ^ Precision)

	return Number .. Suffix
end

It currently gives an error while working with negative numbers one

#2

Number cannot be less than or equal to 0, because this value is either undefined or imaginary in mathematics; log10(0) = undefined and log10(-1) = imaginary number.

I am unsure as to what the purpose of your code is, but if you simply want to get rid of the error, you can either set a minimum value for Number or you can disregard the code whenever Number is ≤ 0.

Example of the former:

if Number <= 0 then 
	Number = 0.01 
end

Example of the latter:

if Number <= 0 then 
	break --replace this with a return instead if needed 
end
#3

Well purpose of code is something like loan, player balance just go negative, like - 20, but this function add suffixes, so like if player balance is 1000 it will say 1K, and i want to do same with negative ones

#4

is Number here a variable for loan ?

#5

you can just treat the negatives as positives, here’s the fixed code (with some better practices…)

local Suffixes = {
    "", " K"," M", " B", " T",
    " Qd", " Qn", " Sx", " Sp",
    " Oc", " No", " De", " Un",
    " Tr", " Qud", " Qun", " Sxd",
    " Spd", " Ocd", " Nod", " Vg",
    " UVg"," DVg"," TVg"," QdVg",
    " QnVg"," SxVg"," SpVg"," OcVg",
    " NoVg"," Tg"," UTg"," DTg"," TTg",
    " QdTg"," QnTg"," SxTg"," SpTg"," OcTg",
    " NoTg"," qg"," Uqg"," Dqg"," Tqg"," Qdqg",
    " Qnqg"," Sxqg"," Spqg"," Ocqg"," Noqg",
    " Qg"," UQg"," DQg"," TQg"," QdQg"," QnQg",
    " SxQg"," SpQg"," OcQg"," NoQg"," sg"," Usg",
    " Dsg"," Tsg"," Qdsg"," Qnsg"," Sxsg"," Spsg",
    " Ocsg","Nosg"," Sg"," USg"," DSg"," TSg",
    " QdSg"," QnSg"," SxSg"," SpSg"," OcSg"," NoSg",
    " Og"," UOg"," DOg"," TOg"," QdOg"," QnOg"," SxOg",
    " SpOg"," OcOg"," NoOg"," Ng"," UNg"," DNg"," TNg",
    " QdNg"," QnNg"," SxNg"," SpNg"," OcNg"," NoNg"
}

local function addSuffix(number, precision)
    number, precision = math.abs(number), math.abs(precision or 2)

	local index = math.max(math.floor(math.log10(number) / 3), 0)
	local suffix = Suffixes[index + 1]

	number = number / (10 ^ (3 * index))
	number = (math.floor(number * 10 ^ precision) / 10 ^ precision)
	local newNumber = (`{number}{suffix}`):gsub(" ", "")
	
	return newNumber
end

You may have noticed that I removed the extra white spaces in the number, for some reason there’s a white space there and I thought it wasn’t intentional, so ya, you can remove the gsub if needed.

To insure it works with negatives, I've added `math.abs` at the top, I also did it with precision and added `or 2`, this means that you shouldn't always pass precision as an argument, the default will be 2!
