             Summary: Use StrictMath for more functions in SYSFUN
                 Key: DERBY-6447
                 URL: https://issues.apache.org/jira/browse/DERBY-6447
             Project: Derby
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 10.11.0.0
            Reporter: Knut Anders Hatlen
            Priority: Minor


Most of the functions in the SYSFUN schema use methods in java.lang.StrictMath 
directly. A few of them use methods in SystemProcedures instead. Java 1.5 added 
more methods to StrictMath, so it is now possible to make more of the functions 
use StrictMath and drop the implementation in SystemProcedures:

- LOG10 could use StrictMath.log10()
- COSH could use StrictMath.cosh()
- SINH could use StrictMath.sinh()
- TANH could use StrictMath.tanh()
