Evaluate AdditiveExpression. 31 2. Call GetValue(Result(1)). 32 3. Evaluate MultiplicativeExpression. 33 4. Call GetValue(Result(3)). 34 5. Call ToNumber(Result(2)). 35 6. Call ToNumber(Result(4)). 36 7. Apply the subtraction operation to Result(5) and Result(6). See the 37 discussion below (11.6.3). 38 8. Return Result(7). 39 40 Author: christine@netscape.com 41 Date: 12 november 1997 42*/ 43 var SECTION = "11.6.2-1"; 44 var VERSION = "ECMA_1"; 45 startTest(); 46 var testcases = getTestCases(); 47 48 writeHeaderToLog( SECTION + " The subtraction operator ( - )"); 49 test(); 50 51function test() { 52 for ( tc=0; tc < testcases.length; tc++ ) { 53 testcases[tc].passed = writeTestCaseResult( 54 testcases[tc].expect, 55 testcases[tc].actual, 56 testcases[tc].description +" = "+ 57 testcases[tc].actual ); 58 59 testcases[tc].reason += ( testcases[tc].passed ) ?
