>             Project: mod_cluster
>          Issue Type: Feature Request
>          Components: Core & Container Integration (Java)
>    Affects Versions: 1.2.13.Final, 1.3.7.Final
>            Reporter: Leandro Quiroga
>            Assignee: Radoslav Husar
>            Priority: Critical
>              Labels: decay
>             Fix For: 1.4.0.Alpha1, 2.0.0.Alpha1

>
> 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.
