[HELP] Decimal number

[..:D&G:..]

Hello peeps, is there a way of getting a text using guiGetText and check if it's a normal whole number?

I want to output an error if the player enters a number with , or ., or a number and a letter, I want to check if the number the player entered in a memo is a whole number.

Thanks.

Hi,

You can do it with a simple regex:

function isValidNumber(number) 
    return string.find(number, "^[+-]?%d+$") and true or false 
end 

Explainations:

^	begining of the string
[+-]?	followed by an optional + or a -
%d+	followed by a digit (so from 0 to 9) one or multiple times
$	followed by the end of the string (so nothing should be after the whole number)

Test it here: http://ideone.com/pyVUMb
