title: Why Oracle SQL SELECT expression doesn't print decimal value?
body: <pre><code>select (4*(22/7)*3958.759*3958.759) as "Earth's Area" from dual;
  
  Prints:
  Earth's Area
  ------------
     197016573
  </code></pre>
  
  <p>It should print 197016572.595304. Why the digits after point were ignored in the output?</p>
