------------------------------------------

             Summary: Double decay factor
                 Key: MODCLUSTER-607
                 URL: https://issues.jboss.org/browse/MODCLUSTER-607
             Project: mod_cluster
          Issue Type: Enhancement
          Components: Core & Container Integration (Java)
    Affects Versions: 1.3.7.Final, 1.2.13.Final
            Reporter: Leandro Quiroga
            Assignee: Jean-Frederic Clere
            Priority: Minor


The int type is too restrictive for specifying the decay factor.
Using a decay factor of 1 means no decay.
Next value is 2, and the importance of loads decreases too fast:

||Instant||Importance||
|0|100%|
|1|50%|
|2|25%|
|3|12.5%|
|4|6.3%|
|5|3.1%|
|6|1.6%|
|7|0.8%|
|8|0.4%|
|9|0.2%|

Next value is 3, and the importance of loads decreases even faster:

||Instant||Importance||
|0|100%|
|1|33%|
|2|11%|
|3|3.7%|
|4|1.2%|
|5|0.4%|
|6|0.1%|
|7|0.0%|
|8|0.0%|
|9|0.0%|
 
Using a double for decay factor isn't complex and allows much more precision.
