+<p>O operador bitwise XOR (<code>^</code>) retorna o numero 1 em cada posição de bit para a qual os bits correspondentes de ambos, mas não de ambos os operandos, são <code>1</code>s.</p>

+
+<p>Os operandos são convertidos em números inteiros de 32 bits e expressados por uma série de bits (zeros e uns). Numeros com mais de 32 bits descartam seus bits mais significativos. Por exemplo, o número inteiro a seguir com mais de 32 bits será convertido em um número inteiro de 32 bits:</p>

+<pre class="brush: js notranslate">Antes: 11100110111110100000000000000110000000000001
+Depois: 10100000000000000110000000000001</pre>
+
+<p>Cada bit no primeiro operando é emparelhado com o bit correspondente no segundo operando: primeiro bit para o primeiro bit, segundo bit para o segundo bit e assim por diante.</p>
+
+<p>O operador é aplicado para cada par de bits e o resultado é construído em bitwise.</p>
