The method by which this mode is selected --- is implementation dependent. --- --- APPLICABILITY CRITERIA: --- This test applies only to implementations supporting the --- Numerics Annex. --- This test only applies to the Strict Mode for numerical --- accuracy. --- --- --- CHANGE HISTORY: --- 18 Mar 96 SAIC Initial release for 2.1 --- 24 Apr 96 SAIC Fixed error bounds. --- 17 Aug 96 SAIC Added reference information and improved --- checking for machines with more than 23 --- digits of precision. --- 03 Feb 97 PWB.CTA Removed checks with explicit Cycle => 2.0*Pi --- 22 Dec 99 RLB Added model range checking to "exact" results, --- in order to avoid too strictly requiring a specific --- result, and too weakly checking results. --- --- 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". --- Phil Brashear ---! - --- --- References: --- --- Software Manual for the Elementary Functions --- William J.
