description: Unsigned right shift always throws for non-primitive BigInt values
|
|
esid: sec-unsigned-right-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::unsignedRightShift(lnum, rnum).
|
|
|
|
Note: BigInt::unsignedRightShift always throws a TypeError
