If Result(1) is NaN, return +0 27 3. If Result(1) is +0, -0, Infinity, or -Infinity, 28 return Result(1). 29 4. Compute sign(Result(1)) * floor(abs(Result(1))). 30 5. Return Result(4). 31 32 To test ToInteger, this test uses new Date(value), 33 15.9.3.7. The Date constructor sets the [[Value]] 34 property of the new object to TimeClip(value), which 35 uses the rules: 36 37 TimeClip(time) 38 1. If time is not finite, return NaN 39 2. If abs(Result(1)) > 8.64e15, return NaN 40 3. Return an implementation dependent choice of either 41 ToInteger(Result(2)) or ToInteger(Result(2)) + (+0) 42 (Adding a positive 0 converts -0 to +0). 43 44 This tests ToInteger for values -8.64e15 > value > 8.64e15, 45 not including -0 and +0. 46 47 For additional special cases (0, +0, Infinity, -Infinity, 48 and NaN, see 9.4-2.js). For value is String, see 9.4-3.js. 49 50 Author: christine (at) netscape.com 51 Date: 10 july 1997 52 53 */ 54 var SECTION = "9.4-1"; 55 var VERSION = "ECMA_1"; 56 startTest(); 57 var TITLE = "ToInteger"; 58 59 writeHeaderToLog( SECTION + " "+ TITLE); 60 61 var testcases = getTestCases(); 62 test(); 63 64 function test() { 65 for ( tc=0; tc < testcases.length; tc++ ) { 66 testcases[tc].passed = writeTestCaseResult( 67 testcases[tc].expect, 68 testcases[tc].actual, 69 testcases[tc].description +" = "+ 70 testcases[tc].actual ); 71 72 73 testcases[tc].passed = writeTestCaseResult( 74 testcases[tc].expect, 75 testcases[tc].actual, 76 testcases[tc].description +" = "+ testcases[tc].actual ); 77 78 testcases[tc].reason += ( testcases[tc].passed ) ?
