How do I set value and suite to a joker card?

in a card game with 104 cards + 4 jokers

how can i set the variable cardvalue + cardsuite to joker to be all other cards value and suite?

i know that setting facevalue is like int(CardDeck.At(DeckCardNumber)%13) +1 and cardsuite floor(CardDeck.At(DeckCardNumber)/13) using an array

but joker can be all suite or value at once

thank you

any tips?
