Detect if textbox number input has decimals?

I was wondering if it’s possible to detect if textbox number input has any decimals on it or not. I tried string.match but it wouldn’t work.
An if statement is preferred.

string.find() might work for you

Did that too and still errors.

4 
local t = "this is a.test"

print("Checking: '".. t.. "'")

if string.find(t,".") then

warn('Has a "."')

end

That code above created a bug. This code does work however it has to loop through the entire text

local t = "this is atet"
 
local hasdot = false
for i=1,string.len(t) do
	if string.sub(t,i,i) == "." then
		hasdot = true
	end
end

if hasdot then
	warn("has dot")
else
	warn("no dot")
end

Is there text written too, or just numbers?

It’s only numbers, no text involved.

Can you share the code you already tried?

Just to this

local text = "2.50"

if tonumber(text) < 0 then 
warn("has dot")
else
warn("no dot")
end

Then I guess this is it:

local textbox = ... -- put textbox here
	if tonumber(textbox.Text) == math.floor(tonumber(textbox.Text)) then
		... -- put code here
	end
