description: Left shift for non-primitive BigInt values

esid: sec-left-shift-operator-runtime-semantics-evaluation

|
info: |
|

ShiftExpression : ShiftExpression << AdditiveExpression
|
|
|
|
1. Let lref be the result of evaluating ShiftExpression.
|
|
2. Let lval be ? GetValue(lref).
|
|
3. Let rref be the result of evaluating AdditiveExpression.
|
|
4. Let rval be ? GetValue(rref).
|
|
5. Let lnum be ? ToNumeric(lval).
|
|
6. Let rnum be ? ToNumeric(rval).
|
|
7. If Type(lnum) does not equal Type(rnum), throw a TypeError exception.
|
|
8. Let T be Type(lnum).
|
|
9. Return T::leftShift(lnum, rnum).
