9 ECMA Section: 11.6.2 The Subtraction operator ( - )
10 Description:
12 The production AdditiveExpression : AdditiveExpression -
13 MultiplicativeExpression is evaluated as follows:
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).
