title: Add two Float values and get up to 2 precision values
body: <p>Can we get up to 2 precision values when we add 2 float values of containing 0 as 2nd precision without changing its <strong>type as Float</strong></p>
  
  <p>I have a snippet like </p>
  
  <pre><code>a = 1.20+1.20
  print a 
  </code></pre>
  
  <p>the output should be like </p>
  
  <pre><code>2.40
  </code></pre>
  
  <p>but I got the output as 2.4 because python rounds off </p>
  
  <p>I've tried like this ,</p>
  
  <pre><code>from decimal import *
  getcontext().prec = 3
  Decimal(1.20)+Decimal(1.20)
  Decimal('2.40')
  </code></pre>
  
  <p>But every time I need to change the precision value! </p>
  
  <p>can we get as 2.40 without changing its type?
  It should contain a float value as 2.40, not a string! </p>
