<description><![CDATA[
Compares each corresponding bit in the binary representation of the values. For each comparison two 1's yield 1, 1 and 0 yield 0, and two 0's yield 0. This is easy to see when we look at the binary representation of numbers<br />
<br />
<pre>  11010110  // 214
& 01011100  // 92
  --------
  01010100  // 84</pre>
<br />
To see the binary representation of a number, use the <b>binary()</b> function with <b>println()</b>.
