Math format help

If there’s a post or site that explains this or perhaps it’s simpler than I though please let me know but I’m saving a number as an attribute on a button and I wish to format it correctly before setting it.

I have a cost calculating the cost of the button and it’s returning a number like 5464758643 and I want it to be like 5460000000 before setting it. How would I go about that.

5439 to be something like 5500
1200075 to be something like 1200000
5464758643 to be something like 5460000000

Just so it’s not just 5000, 100000, 500000000, etc.

local function Format(n: number): number
	local sign = math.sign(n)
	n = math.abs(n)
	return (n - (n % 10 ^ math.floor(math.log(n, 10) - 1))) * sign
end

print(Format(67878798294232))

maybe this would be something you’d like

To add on with more ideas:

local originalNumber = 89223589324
print(originalNumber)

local function Format(n: number): number
	
	local sign = math.sign(n)
	n = math.abs(n)
	return (n - (n % 10 ^ math.floor(math.log(n, 10) - 1))) * sign
	
end

local roundedNumber = Format(originalNumber)
print(roundedNumber)

local suffixTable = {
	
	{value = 1e12,letterSequence = "T"},
	{value = 1e9,letterSequence = "B"},
	{value = 1e6,letterSequence = "M"},
	{value = 1e3,letterSequence = "K"},
	
}

local function abbreviateNumber(number)
	
	for index,suffix in ipairs(suffixTable) do
		
		if number >= suffix.value then
			
			return string.format("%.2f%s",number / suffix.value,suffix.letterSequence)
			
		end
		
	end
	
	return tostring(number)
	
end

local abbreviatedNumber = abbreviateNumber(roundedNumber)
print(abbreviatedNumber)

local extraRoundedNumber = abbreviatedNumber:gsub("(%d+)%.?0*(%a*)$","%1%2")
print(extraRoundedNumber)

thank you for that both of you.
