What's the different between tonumber and tostring

[Hero192]

Hey guys, i want to be sure of these lua functions ,

tonumber  and  tostring 

don't recomand me the lua.org website because it's hard to get it from them.

Give me some examples only if you are sure you know about these functions i wont get something wrong

Thanks

tonumber and tostring are pretty self-explanatory. tonumber converts i.e strings to number and tostring converts to string.

For example:

i have a table i will get something from the table and convert them and tell me if im wrong or right

local Table= {  
{"Jack",900}, 
} 
for index, v in ipairs (Table) do 
outputChatBox(tostring(v[1]).. " got " ..tonumber(v[2]).."$",root,255,0,0) 
end

Clearly wrong. The values in the table are already of the type you're converting to. You use these functions when you have, for example, a variable of type number, and want to convert it to a string type, or vice versa.

You'd use tonumber() if you have a string that you want to convert to a number:

900 == tonumber("900") 
  
-- or 
  
local variable = "1275" 
-- If here you do: 
variable + 50 
-- it will return an error because 'variable' is a string. You'd need to do: 
tonumber(variable) + 50 
  

It's the same otherwise.

  
"900" ~= 900 
  
It'd need to be 
  
"900" == tostring(900) 
  
 

Hope that helps...
