Error left shift of negative value

WebApr 5, 2024 · The << operator is overloaded for two types of operands: number and BigInt.For numbers, the operator returns a 32-bit integer. For BigInts, the operator returns a BigInt. It first coerces both operands to numeric values and tests the types of them. It performs BigInt left shift if both operands becomes BigInts; otherwise, it converts both … WebRight Shift. The bitwise right shift operator ( >>) is analogous to the left one, but instead of moving bits to the left, it pushes them to the right by the specified number of places. The rightmost bits always get dropped: Every time you shift a bit to the right by one position, you halve its underlying value.

Shifting a number left is equivalent to adding zeros (0) to the right of the binary representation of the number.
