title: Ceiling to Nearest 50
body: <p>I can round the elements of <code>A</code> to the nearest integers greater than or equal to <code>A</code></p>
  
  <pre><code>ceil(A)
  </code></pre>
  
  <p>But what about if I want to round it to the nearest 50 greater than or equal to <code>A</code>?</p>
  
  <p>For example, given the following <code>A</code> array,</p>
  
  <pre><code>A=[24, 35, 78, 101, 199];
  </code></pre>
  
  <p>A subroutine should return the following</p>
  
  <pre><code>B=Subroutine(A)=[50, 50, 100, 150, 200];
  </code></pre>
