title: How do I print a double value with full precision using cout?
body: <p>In my <a href="https://stackoverflow.com/questions/553974/why-does-int55-54-in-c">earlier question</a> I was printing a <code>double</code> using <code>cout</code> that got rounded when I wasn't expecting it.  How can I make <code>cout</code> print a <code>double</code> using full precision?</p>
