title: Double values in python
body: <p>I have values like 656364.53 which has to be read from a text file. From my programming experience, I have learnt that is value takes the <code>double</code> data type, to be retained as a proper value. </p>
  
  <p>In <code>python</code> however, it seems that there is only <code>float</code> or the single - precision value. Therefore as per my experience, these values get changed on reading. </p>
  
  <p>How do I get double precision values in python. </p>
