title: Get JSON data where value is nearest to number X
body: <p>I have a user inputted number, X. Along with a list of data in JSON format.</p>
  
  <pre><code>**114**  80  145     175     240     320
  **123**  85  155     190     260     345
  **132**  90  170     205     280     370
  </code></pre>
  
  <p>I would like to match X with the nearest number in the first column and then return the following values in that row.</p>
  
  <p>Not sure if I have formatted the JSON in the best way. But here is what I have so far: <a href="http://jsfiddle.net/wuSux/" rel="nofollow">http://jsfiddle.net/wuSux/</a></p>
