Call ToNumber on the input argument 2. If Result(1) is NaN, return +0 3. If Result(1) is +0, -0, Infinity, or -Infinity, return Result(1). 4. Compute sign(Result(1)) * floor(abs(Result(1))). 5. Return Result(4). To test ToInteger, this test uses new Date(value), 15.9.3.7. The Date constructor sets the [[Value]] property of the new object to TimeClip(value), which uses the rules: TimeClip(time) 1. If time is not finite, return NaN 2. If abs(Result(1)) > 8.64e15, return NaN 3. Return an implementation dependent choice of either ToInteger(Result(2)) or ToInteger(Result(2)) + (+0) (Adding a positive 0 converts -0 to +0). This tests ToInteger for values -8.64e15 > value > 8.64e15, not including -0 and +0. For additional special cases (0, +0, Infinity, -Infinity, and NaN, see 9.4-2.js). For value is String, see 9.4-3.js.
