title: Django save scientific number
body: <p>I'm trying to find a way to format a scientific number and save it into database. My number is read from a csv file. </p>
  
  <p>model.py</p>
  
  <pre><code>class Doc(models.Model):
  ....
      big=models.BigIntegerField(null=True)
  </code></pre>
  
  <p>views.py</p>
  
  <pre><code>for line in csvfile:
      data = Doc()
      data.big=line['big_number']
      data.save()
  </code></pre>
  
  <p>This following code generate this error:</p>
  
  <blockquote>
    <p>invalid literal for int() with base 10: '2,02161E+12'</p>
  </blockquote>
  
  <p>2,02E+12 is the value on csv file when it's read on standart format and 2021610000000 for the number format. I want to store the "2021610000000".
  Is there a way to force reading the csv column as number ? </p>
