-- 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.
