[jira] Created: (DERBY-3398) Support min/max values for Java types float/double in real/double columns

Support min/max values for Java types float/double in real/double columns
-------------------------------------------------------------------------

                 Key: DERBY-3398
                 URL: https://issues.apache.org/jira/browse/DERBY-3398
             Project: Derby
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 10.4.0.0
            Reporter: Knut Anders Hatlen
            Priority: Minor


Derby doesn't support the entire range of valid (finite) values of the Java primitive types double/float in columns with SQL type DOUBLE or REAL. This appears to be a limitation that was introduced for compatibility with DB2. There have been some requests on derby-user that we lift this restriction.

The restriction is enforced by the methods normalizeREAL() and normalizeDOUBLE() in org.apache.derby.iapi.types.NumberDataType.
