One thing you ought to observe is a strict textual identity of all literals.
So, the limit "thirty-point-zero" shouldn't be written as "30.0" in one
place and "30" in another if a seamless or non-overlapping set of intervals
[x,30[ and [30,y] is desired.
(There ought to s.th. like "const" or "fina
Setting a global that is a subclass of the global reference works fine. See

Not really. :) I don't work with ruleflows.
Attached is an implementation using BigDecimal. It should avoid any floating
point problems. Make sure and use BigDecimal with the pure java version if you
want a true measure of relative performance.

Your idea is actually interesting. Although, we would need to take care

Any suggestions?

I need some help placing a cache of compiled regular expressions using the
MatchesEvaluatorsDefinition as a starting point.
Just for a test I placed a static map in the class:

Then in each of the evaluators I have different versions of:

I wonder if there's some way to introduce strictfp into the drl. (I'm not even
sure if that would even solve the problem. But I figure it'd get you in the
ballpark.) But I think it would be useful to be able to inject strictfp into
the declarations of any generated drools classes.

Please ignore the syntax in this posting. Yes, it is suppose to be like
this:
public abstract class Base {
}
I would appreciate if you can explain how I can achieve the polymorphism
behavior in drools (explained in my example). FYI I'm using version 4.0.7.
Thanks!

Well, we can start out with the fact that this is improper java syntax:
class abstract Base () {}
The () is not in a class declaration. Does this code compile for you? :)
