Lua Checking if an storage is numeric

[kito2]

Hey, I need something, a function that check if the storage is a number (in some cases they are strings, don't know why), any one knows?

 

[Bogart]

local x = getCreatureStorage(cid, 1000) -- this can be anything like globalstorage etc
	if isNumber(x) then
		print(x..'is a number!')
	else
		print(x..'is not a number!')
	end

or

local x = getCreatureStorage(cid, 1000) -- this can be anything like globalstorage etc
	if tonumber(x) then
		print(x..'is a number!')
	else
		print(x..'is not a number!')
	end

same thing
