Hi Developers!
I’m excited to share my FormatNumber system for Roblox, which makes displaying numbers in your games clean and professional — perfect for leaderstats, GUIs, or any other statistics.
The system features:
Automatic abbreviation of large numbers (K, M, B, T, Qa, Qi, up to Dc).
Removes unnecessary zeros after decimals: 12.00K → 12K, 12.50K → 12.5K.
Supports negative numbers.
Automatically chooses formatting: small numbers use commas, large numbers use abbreviations.
Example usage in a module:
local FormatNumber = require(game.ReplicatedStorage.FormatNumber)
print(FormatNumber.Format(987))
print(FormatNumber.Format(12345))
print(FormatNumber.Format(12300))
print(FormatNumber.Format(12000))
print(FormatNumber.Format(9876543))
print(FormatNumber.Format(1234567890123))
print(FormatNumber.Format(-1234567890123))
print(FormatNumber.Format(1234567890123456))
Example integration with leaderstats:
local Players = game:GetService("Players")
local FormatNumber = require(game.ReplicatedStorage:WaitForChild("FormatNumber"))
Players.PlayerAdded:Connect(function(player)
local leaderstats = Instance.new("Folder")
leaderstats.Name = "leaderstats"
leaderstats.Parent = player
local Coins = Instance.new("IntValue")
Coins.Name = "Coins"
Coins.Value = 1234567
Coins.Parent = leaderstats
Coins:GetPropertyChangedSignal("Value"):Connect(function()
Coins.Value = FormatNumber.Format(Coins.Value)
end)
end)
This system is perfect for any game with currency, points, experience, or other stats. It makes your UI clean, readable, and professional.
Here is FormatNumber (ModuleScript)
local FormatNumber = {}
local function addCommas(number)
local formatted = tostring(number)
local k
while true do
formatted, k = string.gsub(formatted, "^(-?%d+)(%d%d%d)", '%1,%2')
if k == 0 then break end
end
return formatted
end
local suffixes = {
"", "K", "M", "B", "T", "Qa", "Qi", "Sx", "Sp", "Oc", "No", "Dc"
}
local function abbreviate(number)
local index = 1
local num = math.abs(number) * 1.0
while num >= 1000 and index < #suffixes do
num = num / 1000
index = index + 1
end
local formatted = string.format("%.2f", num)
formatted = string.gsub(formatted, "%.00$", "")
formatted = string.gsub(formatted, "(%.%d)0$", "%1")
if number < 0 then
formatted = "-" .. formatted
end
return formatted .. suffixes[index]
end
function FormatNumber.Format(number)
if math.abs(number) >= 1000 then
return abbreviate(number)
else
return addCommas(number)
end
end
return FormatNumber
