| 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. |
