41 ECMA Section: 9.4 ToInteger
\r
42 Description: 1. Call ToNumber on the input argument
\r
43 2. If Result(1) is NaN, return +0
\r
44 3. If Result(1) is +0, -0, Infinity, or -Infinity,
\r
46 4. Compute sign(Result(1)) * floor(abs(Result(1))).
\r
47 5. Return Result(4).
\r
49 To test ToInteger, this test uses new Date(value),
\r
50 15.9.3.7. The Date constructor sets the [[Value]]
\r
51 property of the new object to TimeClip(value), which
\r
55 1. If time is not finite, return NaN
\r
56 2. If abs(Result(1)) > 8.64e15, return NaN
\r
57 3. Return an implementation dependent choice of either
\r
58 ToInteger(Result(2)) or ToInteger(Result(2)) + (+0)
\r
59 (Adding a positive 0 converts -0 to +0).
\r
61 This tests ToInteger for values -8.64e15 > value > 8.64e15,
\r
62 not including -0 and +0.
\r
64 For additional special cases (0, +0, Infinity, -Infinity,
\r
65 and NaN, see 9.4-2.js). For value is String, see 9.4-3.js.
