title: Why do I get different results from Python Interpreter (2.7.6) and a calculator?
body: <p>I have the following formula:</p>
  
  <blockquote>
    <p>SZT = SZ0 + (((SZ1 - SZ0) / (WMZ1 - WMZ0)) * (WMZT - WMZ0))</p>
  </blockquote>
  
  <p>Example:</p>
  
  <pre><code>86266 + (((168480 - 86266) / (703786 - 510531)) * (703765.0 - 510531))
  </code></pre>
  
  <p>When I use the python interpreter (2.7.6) for this calculation, I got this result:</p>
  
  <pre><code>86266
  </code></pre>
  
  <p>When I use a calculator (Google for example) I got this result:</p>
  
  <pre><code>168471.066239
  </code></pre>
  
  <p>I assume the second is the correct result. </p>
  
  <p>What's wrong about the calculation in Python?</p>
