How can i check if a variable is a string or a number etc ?

Code: Select all

if( type(variable) == "number" ) then
  -- it's a string
elseif( type(variable) == "string" ) then
 -- it's a number
end

However, be aware that in some cases, strings can be numbers and numbers can be strings. That is, "123", "1AC", "0.123" are all strings but can be used as numbers (use tonumber() or tostring() to convert).
