<div class="desc"><p>The bitwise operators work on the bits of an <code>int</code>: <code>&</code> (and), <code>|</code> (or), <code>^</code> (xor), <code>~</code> (not), <code><<</code> (shift left), and <code>>></code> (a logical/unsigned shift right). They are the tools for flag sets, packing several small values into one integer, and fast multiply/divide by powers of two. Precedence is Go-style: <code><<</code>, <code>>></code>, and <code>&</code> bind like <code>*</code> (tightly), while <code>|</code> and <code>^</code> bind like <code>+</code>, and all of them bind <b>tighter than comparison</b> — so <code>flags & MASK == 0</code> means <code>(flags & MASK) == 0</code> with no parentheses.</p></div>
