description: Unary minus for BigInt object wrappers
esid: sec-unary-minus-operator-runtime-semantics-evaluation
info: |
Runtime Semantics: Evaluation
UnaryExpression : - UnaryExpression
1. Let expr be the result of evaluating UnaryExpression.
2. Let oldValue be ? ToNumeric(? GetValue(expr)).
3. Let T be Type(oldValue).
4. Return ? T::unaryMinus(oldValue).
features: [BigInt, Symbol.toPrimitive]
