>
> 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()
