Is there a way to do this with textboxes?
| Input | Desired Outcome | |
|---|---|---|
| 5 | → | 5 |
| 5. | → | 5. |
| 5.a | → | 5. |
| 5.6789 | → | 5.678 |
| 5.00000000 | → | 5.000 |
| - | → | - |
| . | → | 0. |
| -. | → | -0. |
Thanks!

function formatInput(input)
local inputStr = tostring(input):gsub(" ", "")
if inputStr == "-" then
return "-"
elseif inputStr == "." then
return "0."
elseif inputStr == "-." then
return "-0."
end
inputStr = inputStr:match("^[%d%.%-]*")
local dotCount = select(2, inputStr:gsub("%.", ""))
if dotCount > 1 then
inputStr = inputStr:match("^[%d%.]+")
end
inputStr = inputStr:gsub("^(%-?)0+(%d)", "%1%2")
inputStr = inputStr:match("^%-?%d*%.?%d*")
if inputStr:find("%.") then
local integerPart, decimalPart = inputStr:match("^(%-?%d*)%.(%d*)")
if decimalPart and #decimalPart > 4 then
decimalPart = decimalPart:sub(1, 4)
end
inputStr = integerPart .. (decimalPart and "." .. decimalPart or "")
end
if inputStr:sub(-1) == "." then
inputStr = inputStr:sub(1, -2)
end
if inputStr == "-" then
return "-"
elseif inputStr == "" then
return "0"
end
return inputStr
end
print(formatInput("5")) -- Output: "5"
print(formatInput("5.")) -- Output: "5"
print(formatInput("5.a")) -- Output: "5"
print(formatInput("5.6789")) -- Output: "5.6789"
print(formatInput("5.00000000")) -- Output: "5.0000"
print(formatInput("-")) -- Output: "-"
print(formatInput(".")) -- Output: "0."
print(formatInput("-.")) -- Output: "-0."
print(formatInput("5.67891")) -- Output: "5.6789"
print(formatInput("123.456789")) -- Output: "123.4567"
solution pls ty

If you want to apply it to textboxes,
local textBox = wheremytextboxis
function formatInput(input)
local inputStr = tostring(input):gsub(" ", "")
if inputStr == "-" then
return "-"
elseif inputStr == "." then
return "0."
elseif inputStr == "-." then
return "-0."
end
inputStr = inputStr:match("^[%d%.%-]*")
local dotCount = select(2, inputStr:gsub("%.", ""))
if dotCount > 1 then
inputStr = inputStr:match("^[%d%.]+")
end
inputStr = inputStr:gsub("^(%-?)0+(%d)", "%1%2")
inputStr = inputStr:match("^%-?%d*%.?%d*")
if inputStr:find("%.") then
local integerPart, decimalPart = inputStr:match("^(%-?%d*)%.(%d*)")
if decimalPart and #decimalPart > 4 then
decimalPart = decimalPart:sub(1, 4)
end
inputStr = integerPart .. (decimalPart and "." .. decimalPart or "")
end
if inputStr:sub(-1) == "." then
inputStr = inputStr:sub(1, -2)
end
if inputStr == "-" then
return "-"
elseif inputStr == "" then
return "0"
end
return inputStr
end
textBox.FocusLost:Connect(function()
textBox.Text = formatInput(textBox.Text)
end)

Not quite. I can’t enter “5.678” for example, because it seems to erase my . after the 5. Also, I didn’t mention this, but when the textBox is blank, I’d like it to remain blank, and not turn to 0. Thanks!
Try this
function formatInput(input)
local inputStr = tostring(input):gsub(" ", "")
if inputStr == "-" then
return "-"
elseif inputStr == "." then
return "0."
elseif inputStr == "-." then
return "-0."
end
inputStr = inputStr:match("^[%d%.%-]*")
local dotCount = select(2, inputStr:gsub("%.", ""))
if dotCount > 1 then
inputStr = inputStr:match("^[%d%.]+")
end
inputStr = inputStr:gsub("^(%-?)0+(%d)", "%1%2")
inputStr = inputStr:match("^%-?%d*%.?%d*")
if inputStr:find("%.") then
local integerPart, decimalPart = inputStr:match("^(%-?%d*)%.(%d*)")
if decimalPart and #decimalPart > 3 then
decimalPart = decimalPart:sub(1, 3)
end
inputStr = integerPart .. (decimalPart and "." .. decimalPart or "")
end
if inputStr:sub(-1) == "." then
inputStr = inputStr:sub(1, -2)
end
if inputStr == "-" then
return "-"
elseif inputStr == "" then
return "0"
end
return inputStr
end
print(formatInput("5")) -- Output: "5"
print(formatInput("5.")) -- Output: "5"
print(formatInput("5.a")) -- Output: "5"
print(formatInput("5.6789")) -- Output: "5.679"
print(formatInput("5.00000000")) -- Output: "5.000"
print(formatInput("-")) -- Output: "-"
print(formatInput(".")) -- Output: "0."
print(formatInput("-.")) -- Output: "-0."
print(formatInput("5.67891")) -- Output: "5.678"
print(formatInput("123.456789")) -- Output: "123.456"
Almost, I just need “5.” to return “5.” since my code gets updated using TextBoxInstance:GetPropertyChangedSignal("Text"). Thanks!
Appologies for the oversight.
Here is the new improvised version of the function.
function formatInput(input)
local inputStr = tostring(input):gsub(" ", "")
if inputStr == "-" then
return "-"
elseif inputStr == "." then
return "0."
elseif inputStr == "-." then
return "-0."
end
local hasTrailingDot = inputStr:sub(-1) == "."
inputStr = inputStr:match("^[%d%.%-]*")
local dotCount = select(2, inputStr:gsub("%.", ""))
if dotCount > 1 then
inputStr = inputStr:match("^[%d%.]+")
end
inputStr = inputStr:gsub("^(%-?)0+(%d)", "%1%2")
inputStr = inputStr:match("^%-?%d*%.?%d*")
if inputStr:find("%.") then
local integerPart, decimalPart = inputStr:match("^(%-?%d*)%.(%d*)")
if decimalPart and #decimalPart > 3 then
decimalPart = decimalPart:sub(1, 3)
end
inputStr = integerPart .. (decimalPart and "." .. decimalPart or "")
end
if hasTrailingDot and not inputStr:find("%.") then
inputStr = inputStr .. "."
end
if inputStr == "-" then
return "-"
elseif inputStr == "" then
return "0"
end
return inputStr
end
It works! Two things though: Why do you check if inputStr == "-" then at the top and bottom? And can you explain what each section does? What in God’s name is this "^(%-?)0+(%d)", "%1%2" !?
Thanks!
You could also do if the first character is “-” but i just did for quick reasons.
For the random characters, those are string patterns
You can read about string patterns, they extract things from strings.
