<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>.
