--  This package provides the basic computational interface for the generic
--  elementary functions. The C library version interfaces with the routines
--  in the C mathematical library, and is thus quite portable, although it may
--  not necessarily meet the requirements for accuracy in the numerics annex.
--  One advantage of using this package is that it will interface directly to

--  hardware instructions, such as the those provided on the Intel 80x87.
