Alex D Herbert resolved RNG-92.
-------------------------------
Resolution: Fixed
Fix Version/s: 1.3
In master.
> LargeMeanPoissonSampler cannot handle a mean less than 1
> --------------------------------------------------------
>
> Key: RNG-92
> URL: https://issues.apache.org/jira/browse/RNG-92
> Project: Commons RNG
> Issue Type: Bug
> Components: sampling
> Affects Versions: 1.3
> Reporter: Alex D Herbert
> Assignee: Alex D Herbert
> Priority: Major
> Fix For: 1.3
>
>
> The LargeMeanPoissonSampler computes:
> {code:java}
> lambda = Math.floor(mean);
> logLambda = Math.log(lambda);
> {code}
> So if the mean is less than 1 the logLambda is NaN and other precomputed
> factors are based on a lambda of zero. This results in infinite loop within
> the sampler method.
> Fix by removing support for a mean less than 1.
