title: What's the opposite of `fixed` in cout?
body: <p>When using <code>cout</code>, what is the default formatter defined in the <code>&lt;iomanip&gt;</code> header? In other words, once I've set my formatter to <code>fixed</code> using <code>cout &lt;&lt; fixed &lt;&lt; setPrecision(2)</code>, how do I change it back? Or, what am I changing it back <em>to</em>?</p>
