------------------------------------
Summary: 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
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.
