File Name: 9.4-1.js
ECMA Section: 9.4 ToInteger
Description: 1. 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.
