> Wrong encoding of extremely small similarity values

> Key: LUCY-272
> URL: https://issues.apache.org/jira/browse/LUCY-272
> Project: Lucy
> Issue Type: Bug
> Components: Index
> Reporter: Nick Wellnhofer
> Assignee: Nick Wellnhofer
> Fix For: 0.3.4, 0.4.2
>
>
> Due to a missing range check, values smaller than 2^-31 are encoded as 255
> and in Sim#Encode_Norm and subsequently decoded as approximately 2^31. Such
> small values are probably rare but this could cause significant errors when
> calculating similarities.
