-- This package provides the basic computational interface for the
-- generic elementary functions. With the intrinsic/SIMD version, the
-- compiler can use its knowledge of the functions to select the most
-- suitable implementation, including a vector implementation. These
-- interfaces are suitable for cases in which Float and C's float
-- share the same representation.
