WebAug 5, 2024 · The two’s complement of an integer A is given by - (A + 1). ~170 => -(170 + 1) => -171. Here are a few points to note about the 32-bit signed integers used by JavaScript bitwise operators: The most significant (leftmost) bit is called the sign bit. The sign bit is always 0 for positive integers, and 1 for negative integers. Bitwise operators work on binary digits or bits of input values. We can apply these to the integer types – long, int, short, char, and byte. Before exploring the different bitwise operators let's first understand how they work.
