title: Google Chart odd rounding for values
body: <p>So I am using <a href="http://www.ivellios.toron.pl/technikalia/2010/06/22/gvchart-plugin-jquery-with-google-charts/" rel="nofollow noreferrer">this</a> jquery plugin to create a nice pie chart on my website. The problem is that the plugin is rounding the values very oddly.</p>
  
  <p>This is the table I give to it:</p>
  
  <pre><code>        &lt;table id="pieChart"&gt;
              &lt;caption&gt;Priebežné výsledky ankety&lt;/caption&gt;
  
              &lt;thead&gt;
                  &lt;tr&gt;
                      &lt;th&gt;&lt;/th&gt;
                      &lt;th&gt;Túto formu vzdelávania využívame už dlhšiu dobu.&lt;/th&gt;
                      &lt;th&gt;Som zástancom štandardnej prezenčnej formy vzdelávania.&lt;/th&gt;
                      &lt;th&gt;Plánujeme v najbližšom období zaviesť takúto efektívnu formu vzdelávania.&lt;/th&gt;
                      &lt;th&gt;Doteraz som nepočul o takejto forme vzdelávania, ale zaujalo ma to.&lt;/th&gt;
  
                  &lt;/tr&gt;
              &lt;/thead&gt;
                  &lt;tbody&gt;
                  &lt;tr&gt;
                      &lt;th&gt;100&lt;/th&gt;
  
                      &lt;td&gt;7.7&lt;/td&gt;
                      &lt;td&gt;30.8&lt;/td&gt;
  
                      &lt;td&gt;53.8&lt;/td&gt;
                      &lt;td&gt;7.7&lt;/td&gt;
  
                  &lt;/tr&gt;
              &lt;/tbody&gt;
          &lt;/table&gt;
  </code></pre>
  
  <p>But the values that appear in the pie chart are as follows:</p>
  
  <pre><code>7.2 (should be 7.7)
  30.9 (should be 30.8)
  54.6 (should be 53.8)
  7.2 (should be 7.7)
  </code></pre>
  
  <p>What is a reason behind this? I guess this could be some weird rounding at the side of Google Charts API?</p>
  
  <p>UPDATE:</p>
  
  <p>The jquery plugin generates iframe like this:</p>
  
  <pre><code>&lt;iframe scrolling="no" height="300" frameborder="0" width="720" name="Chart_Frame_22518" id="Chart_Frame_22518" marginheight="0" marginwidth="0"&gt;&lt;/iframe&gt;
  </code></pre>
