how to do the #MATH?
 
So I got a problem....
I want to caclulate the precentage of successrate for assassinate for my character
I have made the following stuff....

an alias that will add 1 to attempt for every attempts
a trigger that will, upon success, add 1 to mortal

Lets say that @attempt are 225
and @mortal is 16

How do I make an trigger/alias etc to be able to caclulate the precentage of success?
cause the easy way...
#math prec1 (@attempts-@mortal)
#math prec2 ((@prec1/@attempts)*100)
just wont work...it returns a 0 on the second #math, even when just using #MATH prec2 (@prec1/@attempts) will return a value of 0

Because your basic numbers are integers, the results are integers, including any interim steps. As a result, any number less than 1 will be zero, and prec2 ends up being (0)*100, for the zero result.

If you want to stick with integers, you can do (@prec1*100)/@attempts, which will give you a non-zero result (for any amount <= 1%, anyway).

Also, your percentage of successes would just be (@mortal*100)/@attempts. The other is the percentage of failures.

The #MATH command is not the best method anymore.
It is only retained for backwards compatibility.

prec1=(@attempts-@mortal)
prec2=(@mortal*100.0/@attempts )

That should be all you need, the parser knows the proper order of math, and by using a %float number in the first step of the equation, the results will be float.
