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.
