info: |
BigInt::signedRightShift (x, y)
The abstract operation BigInt::signedRightShift with arguments x and y of type BigInt:
1. Return BigInt::leftShift(x, -y).
sec-numeric-types-bigint-leftShift
BigInt::leftShift (x, y)
The abstract operation BigInt::leftShift with two arguments x and y of BigInt:
1. If y < 0,
a. Return a BigInt representing x divided by 2-y, rounding down to the nearest integer, including for negative numbers.
2. Return a BigInt representing x multiplied by 2y.
NOTE: Semantics here should be equivalent to a bitwise shift, treating the BigInt as an infinite length string of binary two's complement digits.
