mob/Stat()
    //
    statpanel("Stats")
    stat("Level","[src.Level] ([src.MaxExp/src.Exp]%)")



mob
    var
        Exp = 0
mob
    var
        MaxExp = 100


There are no errors but I get this when I run it:

Lanzo Kuryuu (/mob): Stat()
Lanzo Kuryuu (/mob): Stat()
runtime error: Division by zero
proc name: Stat (/mob/Stat)
usr: Lanzo Kuryuu (/mob)
src: Lanzo Kuryuu (/mob)
call stack:

OVER AND OVER AND OVER AND OVER AND OVER!

In my statpanel it only shows the stats that are before "Level". How can I fix this?

Division by zero: You are dividing 100 by 0. I dunno why, but it seems to give you a nasty little bug.

PLUS, the percentage calculation is wrong.
% = (Exp*100)/Max_Exp
(explanation)
Max_Exp = 100(%)
-------- ------
Exp     =  ? (%)

? = Exp * 100
    ---------
     Max_Exp

Also ,at the beggining of your code, add <font color=green>#define DEBUG</font>. On the runtime error, with DEBUG on, DS will display in which line the code was ''wrong''.

Post an update soon ;)

because 0 goes in to N (any number) over 1.#INF times without using up the full value of 0. it's not a bug, it's math :P

Dividing 0 into a number is perfectly fine and gives 0 like we'd want it to. You are trying to pull out a percentage with the wrong formula. It should be (health/maxhealth)*100.

But he just divided something. I don't think that should bug DM/DS...

try dividing anything by 0 on a calculator. Same thing. Not possbile to divide something into no parts. Defies the actual act of divding. Which is why any form of calculator (including a computer) will give you an error that you cannot divide by 0

Dividing by zero will not result in infinite btw.

3/0 = inf/1
0*inf=3*1
0 != 3

Conclusion: There is no infinite, just a point that's very close to it.

Your whole problem is that you assume a number can be divided by zero, which it can't. It's an undefined operation.

And yes, there is infinty. There are entire areas of mathematics based purely on it's existence.

x/0 is undefined, not infinity. This is an important principle in Calculus.

1/infinity is equal to 0, though. It's not really equal to 0, it's just as close to zero as you can get (think 0.00000000~1), this makes it zero for use in math.

You can't use infinity in math like that. It's a concept, not a number.

you forgot to multiply by 100 for the % :P

Also, I recommend the round() proc >_>
