title: Julia: LoadError: UndefVarError: setrounding not defined
body: <p>I am following along the "Julia Language Documentation Release 0.5.0-dev" and running some of their demo commands, this one is throwing an error. (reference page 28)</p>
  
  <pre><code>setrounding(BigFloat, RoundDown) do
  BigFloat(1) + parse(BigFloat, "0.1")
  end
  </code></pre>
  
  <p>throwing error:</p>
  
  <blockquote>
    <p>ERROR: UndefVarError: setrounding not defined</p>
  </blockquote>
  
  <p>but it does not seem like setrounding should be a variable, but a function.</p>
