title: How can I print a C double bit-by-bit to see the low-level representation?
body: <p>I want to learn how the computer represents the <code>double</code> type in bit, but the <code>&amp;</code> and <code>|</code> bit operators can't use <code>double</code>. And <code>memcpy(&amp;d, &amp;src, 8)</code> also doesn't seem to work.  Any suggestions?</p>
