I'm using Cmud 3.08, and for the life of me I just cannot calculate a percentage.

The bar I want to trigger is this:
{F:At} B: 1/56% GTNL: 8357352 LAST: 297 SKILLS: 6291085 (TH)

My trigger is set up for this:
GTNL: (%d) LAST: (%d) SKILLS: (%d)

And well I've somewhat butchered the trigger but it looks SOMETHING like this:
#var g2n %1
#var skillgxp %3
#math gxperc %format(3,(@g2n)/(@g2n+@skillgxp))
#sub {G2N: %format(3, (@gxperc))~% Last: %2 Skills: %3}

It was working until the number changed, now it doesn't work anymore. I had to add the %format to allow for the decimal, but that's not working anymore. Why can't I just simply have it calculate the number, it always returns 0 instead of .85 (85%)

Anyone help please?

You need to use %float. Otherwise, CMUD returns a rounded value instead.

#MATH gxperc %float(%1)/(%1+%3) will work.

Alternatively, you can multiply the result by 100 to get the answer, too.

I tried *100, but since it already returned 0 it didn't work :(

Thanks, %float worked.

You can get it to work by multiplying by 100, as Charneus suggested. To do this, you have to do the multiplication before the division. It is the division that ends up rounding. So:
#MATH gxperc (%1 * 100)/(%1+%3)

...but beware if (%1 * 100) will exceed 32-bit limit for integer values. I've noticed your GNTL value is relatively big, so this may an issue for you.

Actually, CMUD performs most of it's intermediate calculations using 64-bit integers these days, so it shouldn't be a problem.

Heh, I used almost the same expression in my own script 1,5 years ago and hit the 32-bit limit with easy. Here is my old thread: http://forums.zuggsoft.com/forums/viewtopic.php?t=28501 Reading your explanation there I doubt that this problem can be easily fixed, better leave it "as is".
