title: How to cast float to string with no exponents in BigQuery
body: <p>I have float data in a BigQuery table like 5302014.2 and 5102014.4. </p>
  
  <p>I'd like to run a BigQuery SQL that returns the values in String format, but the following SQL yields this result:</p>
  
  <pre><code>select a, string(a) from my_table
  
  5302014.2    "5.30201e+06"
  5102014.4    "5.10201e+06"
  </code></pre>
  
  <p>How can I rewrite my SQL to return:</p>
  
  <pre><code>5302014.2    "5302014.2"
  5102014.4    "5102014.4"
  </code></pre>
