--------------------------------------

             Summary: [C++] Determine how we want to handle hashing of floating point edge cases
                 Key: ARROW-4497
                 URL: https://issues.apache.org/jira/browse/ARROW-4497
             Project: Apache Arrow
          Issue Type: Bug
          Components: C++
            Reporter: Micah Kornfield
             Fix For: 0.14.0


We should document expected behavior or implement improvements to hashing floating point code:
1.  -0.0 and 0.0 (should these be collapsed to 0.0)
2. NaN (Should we reduce to a single canonical version).
