<p><strong>비트 연산자</strong>는 피연산자를 10진수, 16진수, 8진수가 아니라, 32개의 비트(0과 1) 집합으로 취급합니다. 예를 들어, 10진수 9의 2진수 표기법은 1001입니다. 이렇게, 비트 연산자는 값의 2진수 표현을 사용해 연산하지만, 결과는 표준 JavaScript 숫자 값으로 반환합니다.</p>

<p>The operands of all bitwise operators are converted to signed 32-bit integers in two's <a href="https://en.wikipedia.org/wiki/Method_of_complements">complement format</a>, except for zero-fill right shift which results in an unsigned 32-bit integer.</p>

<p><em>Two's complement format</em> means that a number's negative counterpart (e.g. <code>5</code> vs. <code>-5</code>) is all the number's bits inverted (bitwise NOT of the number, or <em>ones' complement</em> of the number) plus one.</p>

<p>For example, the following encodes the integer <code>314</code>:</p>

<pre>00000000000000000000000100111010
</pre>

<p>The following encodes <code>~314</code>, i.e. the one's complement of <code>314</code>:</p>

<pre>11111111111111111111111011000101
</pre>

<p>Finally, the following encodes <code>-314,</code> i.e. the two's complement of <code>314</code>:</p>

<pre>11111111111111111111111011000110
</pre>

<p>The two's complement guarantees that the left-most bit is 0 when the number is positive and 1 when the number is negative. Thus, it is called the <em>sign bit</em>.</p>

<p>The number <code>0</code> is the integer that is composed completely of 0 bits.</p>

<pre>0 (base 10) = 00000000000000000000000000000000 (base 2)
</pre>

<p>The number <code>-1</code> is the integer that is composed completely of 1 bits.</p>

<pre>-1 (base 10) = 11111111111111111111111111111111 (base 2)
</pre>

<p>The number <code>-2147483648</code> (hexadecimal representation: <code>-0x80000000</code>) is the integer that is composed completely of 0 bits except the first (left-most) one.</p>

<pre>-2147483648 (base 10) = 10000000000000000000000000000000 (base 2)
</pre>

<p>The number <code>2147483647</code> (hexadecimal representation: <code>0x7fffffff</code>) is the integer that is composed completely of 1 bits except the first (left-most) one.</p>

<pre>2147483647 (base 10) = 01111111111111111111111111111111 (base 2)
</pre>

<p>The numbers <code>-2147483648</code> and <code>2147483647</code> are the minimum and the maximum integers representable throught a 32bit signed number.</p>

<h2 id="비트_시프트_연산자">비트 시프트 연산자</h2>

<p>The bitwise shift operators take two operands: the first is a quantity to be shifted, and the second specifies the number of bit positions by which the first operand is to be shifted. The direction of the shift operation is controlled by the operator used.</p>

<p>Shift operators convert their operands to 32-bit integers in big-endian order and return a result of the same type as the left operand. The right operand should be less than 32, but if not only the low five bits will be used.</p>

<h3 id="&lt;&lt;_Left_shift"><a id="Left_shift" name="Left_shift">&lt;&lt; (Left shift)</a></h3>

<p>This operator shifts the first operand the specified number of bits to the left. Excess bits shifted off to the left are discarded. Zero bits are shifted in from the right.</p>

<p>For example, <code>9 &lt;&lt; 2</code> yields 36:</p>

<pre>     9 (base 10): 00000000000000000000000000001001 (base 2)
                  --------------------------------
9 &lt;&lt; 2 (base 10): 00000000000000000000000000100100 (base 2) = 36 (base 10)
</pre>

<p>Bitwise shifting any number <strong>x</strong> to the left by <strong>y</strong> bits yields <strong>x * 2^y</strong>.</p>

<h3 id=">>_Sign-propagating_right_shift"><a id="Right_shift" name="Right_shift">&gt;&gt; (Sign-propagating right shift)</a></h3>

<p>This operator shifts the first operand the specified number of bits to the right. Excess bits shifted off to the right are discarded. Copies of the leftmost bit are shifted in from the left. Since the new leftmost bit has the same value as the previous leftmost bit, the sign bit (the leftmost bit) does not change. Hence the name "sign-propagating".</p>

<p>For example, <code>9 &gt;&gt; 2</code> yields 2:</p>

<pre>     9 (base 10): 00000000000000000000000000001001 (base 2)
                  --------------------------------
9 &gt;&gt; 2 (base 10): 00000000000000000000000000000010 (base 2) = 2 (base 10)
</pre>

<p>Likewise, <code>-9 &gt;&gt; 2</code> yields -3, because the sign is preserved:</p>

<pre>     -9 (base 10): 11111111111111111111111111110111 (base 2)
                   --------------------------------
-9 &gt;&gt; 2 (base 10): 11111111111111111111111111111101 (base 2) = -3 (base 10)
</pre>

<h3 id=">>>_Zero-fill_right_shift"><a id="Unsigned_right_shift" name="Unsigned_right_shift">&gt;&gt;&gt; (Zero-fill right shift)</a></h3>

<p>This operator shifts the first operand the specified number of bits to the right. Excess bits shifted off to the right are discarded. Zero bits are shifted in from the left. The sign bit becomes 0, so the result is always non-negative.</p>

<p>For non-negative numbers, zero-fill right shift and sign-propagating right shift yield the same result. For example, <code>9 &gt;&gt;&gt; 2</code> yields 2, the same as <code>9 &gt;&gt; 2</code>:</p>

<pre>      9 (base 10): 00000000000000000000000000001001 (base 2)
                   --------------------------------
9 &gt;&gt;&gt; 2 (base 10): 00000000000000000000000000000010 (base 2) = 2 (base 10)
</pre>

<p>However, this is not the case for negative numbers. For example, <code>-9 &gt;&gt;&gt; 2</code> yields 1073741821, which is different than <code>-9 &gt;&gt; 2</code> (which yields -3):</p>

<pre>      -9 (base 10): 11111111111111111111111111110111 (base 2)
                    --------------------------------
-9 &gt;&gt;&gt; 2 (base 10): 00111111111111111111111111111101 (base 2) = 1073741821 (base 10)
</pre>

<h3 id="Flags_and_bitmasks">Flags and bitmasks</h3>

<p>The bitwise logical operators are often used to create, manipulate, and read sequences of <em>flags</em>, which are like binary variables. Variables could be used instead of these sequences, but binary flags take much less memory (by a factor of 32).</p>

<p>Suppose there are 4 flags:</p>

<ul>
 <li>flag A: we have an ant problem</li>
 <li>flag B: we own a bat</li>
 <li>flag C: we own a cat</li>
 <li>flag D: we own a duck</li>
</ul>

<p>These flags are represented by a sequence of bits: DCBA. When a flag is <em>set</em>, it has a value of 1. When a flag is <em>cleared</em>, it has a value of 0. Suppose a variable <code>flags</code> has the binary value 0101:</p>

<pre class="brush: js">var flags = 5;   // binary 0101
</pre>

<p>This value indicates:</p>

<ul>
 <li>flag A is true (we have an ant problem);</li>
 <li>flag B is false (we don't own a bat);</li>
 <li>flag C is true (we own a cat);</li>
 <li>flag D is false (we don't own a duck);</li>
</ul>

<p>Since bitwise operators are 32-bit, 0101 is actually 00000000000000000000000000000101, but the preceding zeroes can be neglected since they contain no meaningful information.</p>

<p>A <em>bitmask</em> is a sequence of bits that can manipulate and/or read flags. Typically, a "primitive" bitmask for each flag is defined:</p>

<pre class="brush: js">var FLAG_A = 1; // 0001
var FLAG_B = 2; // 0010
var FLAG_C = 4; // 0100
var FLAG_D = 8; // 1000
</pre>

<p>New bitmasks can be created by using the bitwise logical operators on these primitive bitmasks. For example, the bitmask 1011 can be created by ORing FLAG_A, FLAG_B, and FLAG_D:</p>

<pre class="brush: js">var mask = FLAG_A | FLAG_B | FLAG_D; // 0001 | 0010 | 1000 =&gt; 1011
</pre>

<p>Individual flag values can be extracted by ANDing them with a bitmask, where each bit with the value of one will "extract" the corresponding flag. The bitmask <em>masks</em> out the non-relevant flags by ANDing with zeros (hence the term "bitmask"). For example, the bitmask 0100 can be used to see if flag C is set:</p>

<pre class="brush: js">// if we own a cat
if (flags &amp; FLAG_C) { // 0101 &amp; 0100 =&gt; 0100 =&gt; true
   // do stuff
}
</pre>

<p>A bitmask with multiple set flags acts like an "either/or". For example, the following two are equivalent:</p>

<pre class="brush: js">// if we own a bat or we own a cat
if ((flags &amp; FLAG_B) || (flags &amp; FLAG_C)) { // (0101 &amp; 0010) || (0101 &amp; 0100) =&gt; 0000 || 0100 =&gt; true
   // do stuff
}
</pre>

<pre class="brush: js">// if we own a bat or cat
var mask = FLAG_B | FLAG_C; // 0010 | 0100 =&gt; 0110
if (flags &amp; mask) { // 0101 &amp; 0110 =&gt; 0100 =&gt; true
   // do stuff
}
</pre>

<p>Flags can be set by ORing them with a bitmask, where each bit with the value one will set the corresponding flag, if that flag isn't already set. For example, the bitmask 1100 can be used to set flags C and D:</p>

<pre class="brush: js">// yes, we own a cat and a duck
var mask = FLAG_C | FLAG_D; // 0100 | 1000 =&gt; 1100
flags |= mask;   // 0101 | 1100 =&gt; 1101
</pre>

<p>Flags can be cleared by ANDing them with a bitmask, where each bit with the value zero will clear the corresponding flag, if it isn't already cleared. This bitmask can be created by NOTing primitive bitmasks. For example, the bitmask 1010 can be used to clear flags A and C:</p>

<pre class="brush: js">// no, we don't have an ant problem or own a cat
var mask = ~(FLAG_A | FLAG_C); // ~0101 =&gt; 1010
flags &amp;= mask;   // 1101 &amp; 1010 =&gt; 1000
</pre>

<p>The mask could also have been created with <code>~FLAG_A &amp; ~FLAG_C</code> (De Morgan's law):</p>

<pre class="brush: js">// no, we don't have an ant problem, and we don't own a cat
var mask = ~FLAG_A &amp; ~FLAG_C;
flags &amp;= mask;   // 1101 &amp; 1010 =&gt; 1000
</pre>

<p>Flags can be toggled by XORing them with a bitmask, where each bit with the value one will toggle the corresponding flag. For example, the bitmask 0110 can be used to toggle flags B and C:</p>

<pre class="brush: js">// if we didn't have a bat, we have one now, and if we did have one, bye-bye bat
// same thing for cats
var mask = FLAG_B | FLAG_C;
flags = flags ^ mask;   // 1100 ^ 0110 =&gt; 1010
</pre>

<p>Finally, the flags can all be flipped with the NOT operator:</p>

<pre class="brush: js">// entering parallel universe...
flags = ~flags;    // ~1010 =&gt; 0101
</pre>

  // nMask must be between -2147483648 and 2147483647
  if (nMask &gt; 0x7fffffff || nMask &lt; -0x80000000) { throw new TypeError("arrayFromMask - out of range"); }
  for (var nShifted = nMask, aFromMask = []; nShifted; aFromMask.push(Boolean(nShifted &amp; 1)), nShifted &gt;&gt;&gt;= 1);
  return aFromMask;
}

var array1 = arrayFromMask(11);
var array2 = arrayFromMask(4);
var array3 = arrayFromMask(1);

alert("[" + array1.join(", ") + "]");
// prints "[true, true, false, true]", i.e.: 11, i.e.: 1011
</pre>

<p>You can test both algorithms at the same time…</p>

<pre class="brush: js">var nTest = 19; // our custom mask
var nResult = createMask.apply(this, arrayFromMask(nTest));

alert(nResult); // 19
</pre>

<p>For didactic purpose only (since there is the <code><a href="/en-US/docs/JavaScript/Reference/Global_Objects/Number/toString" title="/en-US/docs/JavaScript/Reference/Global_Objects/Number/toString">Number.toString(2)</a></code> method), we show how it is possible to modify the <code>arrayFromMask</code> algorithm in order to create a <code><a href="/en-US/docs/JavaScript/Reference/Global_Objects/String" title="/en-US/docs/JavaScript/Reference/Global_Objects/String">string</a></code> containing the binary representation of a <code><a href="/en-US/docs/JavaScript/Reference/Global_Objects/Number" title="/en-US/docs/JavaScript/Reference/Global_Objects/Number">number</a></code>, rather than an <code><a href="/en-US/docs/JavaScript/Reference/Global_Objects/Array" title="/en-US/docs/JavaScript/Reference/Global_Objects/Array">array</a></code> of <code><a href="/en-US/docs/JavaScript/Reference/Global_Objects/Boolean" title="/en-US/docs/JavaScript/Reference/Global_Objects/Boolean">booleans</a></code>:</p>

<pre class="brush: js">function createBinaryString (nMask) {
  // nMask must be between -2147483648 and 2147483647
  for (var nFlag = 0, nShifted = nMask, sMask = ""; nFlag &lt; 32; nFlag++, sMask += String(nShifted &gt;&gt;&gt; 31), nShifted &lt;&lt;= 1);
  return sMask;
}

var string1 = createBinaryString(11);
var string2 = createBinaryString(4);
var string3 = createBinaryString(1);

alert(string1);
// prints 00000000000000000000000000001011, i.e. 11
