when players go to sell the ore
it takes 50 ore to get 1 credit

how can i make it so there is no 1.4256646 credits?

rounding off?

I think there is a round proc, like

mob/var
    credits = 0
    ores = 50

mob/Ore_Buyer/verb/Sell_Ores(/mob/Ore_Buyer in oview(1))
    if(ores == 50)
        credits = round([ores]/[credits])


I don't really know what you're doing, so it would help a lot if you could give a code snippet. Or if you want to just look up "round" when you press "F1" in the Dream Maker.

sorry,

    verb/Sell_ore()
        set src in oview(1)
        if(usr.ore<=49)
            usr<<"You need to mine some ore first!, The smallest amount they will buy is 50"
            return
        switch(input("Would you like to sell all your ore?") in list ("Yes","No"))
            if("Yes")
                var/X = usr.ore / 50
                var/Y = X * 50
                usr.credit = X + usr.credit
                usr.ore -= Y
            if("No")
                return


see, user can have more then 50 ore so if he has 75 ore he would get 1.5 credits i dont want it to cash the other 25 in??? is that possible??

                    ++usr.credit// adds one credit to the user
                    usr.ore=max(0,usr.ore-50) // subtracts 50 ore from the user


There you go

Except he wants to sell as many units of 50 ore for 1 credit each, all at once. Which means two lines of code:

usr.credit += round(ore/50) //add one credit per 50 units of ore, rounded down
usr.ore = usr.ore%50 //set ore equal to the remainder of ore/50


The % (modulo) operator is, essentially, the remainder operator. So, 75%50 = 25, 120%50 = 20, etc.
