The first two packages differ only in the --- floating point type that is being tested. The first --- and third package differ only in whether the generic --- elementary functions package or the pre-instantiated --- package is used. --- The test package is not generic so that the arguments --- and expected results for some of the test values --- can be expressed as universal real instead of being --- computed at runtime. --- --- SPECIAL REQUIREMENTS --- The Strict Mode for the numerical accuracy must be --- selected. 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: --- 2 FEB 96 SAIC Initial release for 2.1 --- 18 AUG 96 SAIC Made Check consistent with other tests. --- ---! - -with System;
