Question in Panamaconferentie
1) Randomiseer een waarde, bijvoorbeeld de prijs, en pas alles aan zodat het automatisch werkt.
Een nuttig commando is
precround(...,2)
wat een getal op 2 cijfers na de komma afrondt.2) Randomiseer alle waardes. Het ideaalst lijkt mij het aantal initiële appels, de prijs van toen, en hoeveel appels je finaal zou kopen. Je kan dit doen door een lijst van goeie opties manueel in te geven, of door automatisch een goeie situatie te selecteren (moeilijker).
Een nuttig commando is
gcd(a,b)
wat de grootste gemene deler geeft van 2 getallen (voor de middelste kolom in de verhoudingstabel). -
