title: Round a float UP to next odd integer
body: <p>How can I round a float <strong>up</strong> to the <strong>next</strong> odd integer? I found how it can be done for even numbers <a href="https://stackoverflow.com/questions/25361757/python-2-7-round-a-float-up-to-next-even-number">here</a>. So I tried something like:</p>
  <pre><code>import numpy as np
  
  def round_up_to_odd(f):
      return np.ceil(f / 2.) * 2 + 1
  </code></pre>
  <p>But of course this does not round it to the NEXT odd number:</p>
  <pre><code>&gt;&gt;&gt; odd(32.6)
  35.0
  </code></pre>
  <p>Any suggestions?</p>
