1.11 + File Name: 11.6.2-1.js
1.12 + ECMA Section: 11.6.2 The Subtraction operator ( - )
1.13 + Description:
1.14 +
1.15 + The production AdditiveExpression : AdditiveExpression -
1.16 + MultiplicativeExpression is evaluated as follows:
1.17 +
1.18 + 1. Evaluate AdditiveExpression.
1.19 + 2. Call GetValue(Result(1)).
1.20 + 3. Evaluate MultiplicativeExpression.
1.21 + 4. Call GetValue(Result(3)).
1.22 + 5. Call ToNumber(Result(2)).
1.23 + 6. Call ToNumber(Result(4)).
1.24 + 7. Apply the subtraction operation to Result(5) and Result(6). See the
1.25 + discussion below (11.6.3).
1.26 + 8. Return Result(7).
