Because I need the precision of a double , for example :
if totalAmount = 150.3
1) t : Bill($amount : totalAmount, totalAmount < 150.0);
=> the rule will be fired (and should not be)
2) t : Bill($amount : totalAmount, totalAmount < (new
< Double(150.0).doubleValue()));
=> the condition will be not be satisfied
I solve my first problem.

Not addressing your stated problem, but I have one question: why are you
using this expression: "new Double(150.0).doubleValue()"
Why not just use "150.0"?
