[rules-users] Problem with updated facts

[thomas moncieu]

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.
