[dudeks]

Hi.

I need a function isNumeric() to check an writed to gui text.

Anywho have this function? :>

[LoveFist]

function isNumeric(text) 
return tonumber(text) 
end 

[karlis]

function isNumeric(text) 
return tonumber(text) 
end 

correction

  
function isNumeric(text) 
return tonumber(text) and true or false 
end 
  

[dudeks]

If text is: "18a" > \main_s.lua:174: attempt to compare number with nil

It's don't work. I test it some times ago.

function isNumeric(value) 
if(value == tonumber(value))then 
return true 
else 
return false 
end

This same.

main_s.lua:174: attempt to compare number with nil

show how you are calling the function in your script

[karlis]

function isNumeric(text) 
  if type(text)~="string" and type(text)~="number" then return false end 
  return tonumber(text) and true or false 
end 
  

[dudeks]

age = guiGetText(editage) 
 if isNumeric(age) then 
    .... 
end 

edit:

function isNumeric(text) 
  if type(text)~="string" and type(text)~="number" then return false end 
  return tonumber(text) and true or false 
end 
  

is working. Thanks!

Weird, I had:

  
function isNumeric(text) 
    if type(text) ~= "string" then 
        text = tostring(text) 
    end 
    return tonumber(text) and true or false 
end 
  

[karlis]

function isNumeric(text) 
    if type(text) == "string" then 
        text = tostring(text) 
    end 
    return text and true or false 
end
