title: Astyanax Cassandra Double type precision
body: <p>I'm trying to get a Double value from a Cassandra table with a double type column. I've created the table in CQL3 syntax:</p>
  
  <pre><code>CREATE TABLE data_double (
      datetime timestamp,
      value double,
      primary key (datetime)
      );
  </code></pre>
  
  <p>I've inserted a row:</p>
  
  <pre><code>INSERT INTO data_double (datetime,  value) VALUES ('111111111', 123.456);  
  </code></pre>
  
  <p>When I do:</p>
  
  <pre><code>SELECT * from data_double;
  </code></pre>
  
  <p>I get that the value is <strong>123.46</strong></p>
  
  <p>Why is the value rounded?</p>
  
  <p>Thanks</p>
