There is $ORACLE_HOME/rdbms/admin/stdspec.sql and stdbody.sql (used to be standard.sql in earlier versions), but I suspect this is just the way in which SQL builtins are made available to pl/sql, rather than a complete indication of what the SQL builtins can do.

Is there any file in an Oracle installation that provides the declarations to the built-in functions? For example, I'd like to see how functions like CEIL are declared, and whether they are overloaded to accept the newly-supported, IEEE-754 floating-point types as input.
