23    File Name:          9.4-1.js
24    ECMA Section:       9.4 ToInteger
25    Description:        1.  Call ToNumber on the input argument
26                        2.  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.
