guiGetText as a number?

[Karuzo]

Hey Guys,

I wanted to ask if there is a possibility to check if a text from an edit box is a number and not a string.

But as guiGetText retursn the text as a string idk how to solve this.

I think i could do it with a table which is filled with numbers and check if its a number. But is there no other way to do this?

You can just simply use tonumber.

Example:

if ( not tonumber ( guiGetText ( myEdit ) ) ) then 
       return outputChatBox ( "Invalid number" ) 
end

local number = tonumber ( guiGetText ( myGUIElement ) ) 
if ( number ) then 
-- is a number 
end

'tonumber' returns 'nil' if the given string is not a number.
