title: Ruby: Rounding float in Ruby
body: <p>I'm having problems rounding.  I have a float, which I want to round to the hundredth of a decimal.  However, I can only use <code>.round</code> which basically turns it into an int, meaning <code>2.34.round # =&gt; 2.</code>  Is there a simple effect way to do something like <code>2.3465 # =&gt; 2.35</code></p>
