Might someone say use me like math.abs?, in my ot I have a bankSystem via talkaction, but if the person for example deposits a quantity with a negative value (Ex-:!deposit -150000000), the quantity will be added and when he should withdraw of his balance, will be able to extract this quantity of money though it did not have it :S!, for this reason I need to be able place like in the script, which negative values could not use, Raliuga said to me that it might do it using the function "math.abs"
