| 9 ECMA Section: 11.6.2 The Subtraction operator ( - ) | |
| 10 Description: | |
| 11 | |
| 12 The production AdditiveExpression : AdditiveExpression - | |
| 13 MultiplicativeExpression is evaluated as follows: | |
| 14 | |
| 15 1. Evaluate AdditiveExpression. | |
| 16 2. Call GetValue(Result(1)). | |
| 17 3. Evaluate MultiplicativeExpression. | |
| 18 4. Call GetValue(Result(3)). | |
| 19 5. Call ToNumber(Result(2)). | |
| 20 6. Call ToNumber(Result(4)). | |
| 21 7. Apply the subtraction operation to Result(5) and Result(6). See the | |
| 22 discussion below (11.6.3). | |
| 23 8. Return Result(7). | |
