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 x86. -- Note: there are two versions of this package. One using the normal IEEE -- 64-bit double format (which is this version), and one using 80-bit x86 -- long double (see file 4onumaux.ads). package Ada.Numerics.Aux is pragma Pure (Aux); -- This version omits the pragma linker_options ("-lm") since there is -- no libm.a library for VxWorks. type Double is digits 15; -- Type Double is the type used to call the C routines -- We import these functions directly from C.
