title: How to store precise decimal degree coordinates in a MySQL database
body: <p>I've created a database using the store locator tutorial on Google Code, which specifies that the fields to store marker coordinates be of type <code>FLOAT(10,6)</code>. However, when I geocode certain points using Google's geocoder service I get some results with 14 decimal places. For example,</p>
  
  <p><code>-70.07290899999998</code></p>
  
  <p>The numbers are never more than 21 or less than -67 and always have between 1 and 14 digits after the decimal point.</p>
  
  <p>How do I set this field in the database?</p>
