------------------------------------
Summary: Half floats
Key: LUCENE-7289
URL: https://issues.apache.org/jira/browse/LUCENE-7289
Project: Lucene - Core
Issue Type: New Feature
Reporter: Adrien Grand
Assignee: Adrien Grand
Priority: Minor
When it comes to indexing floating-point data, doubles and floats are quite
space-intensive even though full precision is rarely needed. So maybe we should
consider exposing half floats?
Half floats have 5 bits for the exponent and 11 bits (including the implicit
bit) for the mantissa so the minimum value is ~6x10^−8^, the maximum is
65504 and they can represent all integers between -2048 and 2048 accurately.
