The functions --- are used as the right hand of assignment statements, as part of --- conditional statements, and as arguments in other function calls. --- --- A check is performed in the test to determine whether the bit --- ordering method used by the machine/implementation is high-order --- first ("Big Endian") or low-order first ("Little Endian"). The --- specific subtests use this information to evaluate the results of --- each of the functions under test. --- --- Note: In the string associated with each Report.Failed statement, the --- acronym BE refers to Big Endian, LE refers to Little Endian. --- --- APPLICABILITY CRITERIA: --- This test is applicable to all implementations that support signed --- and modular integer types of 8 bits. --- --- --- CHANGE HISTORY: --- 21 Aug 95 SAIC Initial prerelease version. --- 07 May 96 SAIC Incorporated reviewer comments for ACVC 2.1. --- ---! - -with Report;
