+--
+-- OBJECTIVE:
+--      Check that the functions Arcsin and Arcsinh provide correct 
+--      results.
+--
+-- TEST DESCRIPTION:
+--      This test examines both the version of Arcsin and Arcsinh 
+--      the instantiation of the Ada.Numerics.Generic_Elementary_Functions 
+--      with a type derived from type Float, as well as the preinstantiated 
+--      version of this package for type Float.
+--      Prescribed results, including instances prescribed to raise 
+--      exceptions, are examined in the test cases.  In addition, 
+--      certain evaluations are performed where the actual function result 
+--      is compared with the expected result (within an epsilon range of 
+--      accuracy).
+--
+-- TEST FILES:
+--      The following files comprise this test:
+--
+--         FXA5A00.A   (foundation code)
+--         CXA5A05.A
+--
+--
+-- CHANGE HISTORY:
+--      20 Mar 95   SAIC    Initial prerelease version.
+--      06 Apr 95   SAIC    Corrected errors in context clause reference and
+--                          use of Cycle parameter.
+--      13 Jun 95   SAIC    Incorporated use of Dont_Optimize procedure, and
+--                          use of Result_Within_Range function overloaded for
+--                          FXA5A00.New_Float_Type.
+--      28 Feb 97   PWB.CTA Removed checks with explict Cycle => 2.0*Pi
+--
+-- CHANGE NOTE:
+--      According to Ken Dritz, author of the Numerics Annex of the RM,
+--      one should never specify the cycle 2.0*Pi for the trigonometric
+--      functions.  In particular, if the machine number for the first
+--      argument is not an exact multiple of the machine number for the
+--      explicit cycle, then the specified exact results cannot be
+--      reasonably expected.  The affected checks in this test have been
+--      marked as comments, with the additional notation "pwb-math".
