title: Finding numeric characters using wildcards in countif
body: <p>I have a countif function, using which I want to count those cells which have a numeric character anywhere.</p>
  
  <pre><code>Column A
  Rich-Dilg-street 3
  I have 4 apples
  I have seven dogs
  </code></pre>
  
  <p>How do I write the <code>countif</code> criteria using wildcards in such a way that I can count those which have a numeric character? In the above example, the answer should 2 (1 and 2 not 3)</p>
