title: How to NOT round a value using kable
body: <p>I am trying to make an ANOVA table for some data collection. Here is the r code:</p>
  
  <pre><code>```{r 2e anova}
  bigaov = anova(bigmod) 
  bigaov[2:4] = round(bigaov[2:4], 2)
  options(knitr.kable.NA = '-')
  kable(bigaov, col.names = c("Df", "Sum Sq", "Mean Sq", "F-Value", "P- 
  Value"),
  caption = '\\label{tab:bigaov} The ANOVA table for two-way complete model.')
  ```
  </code></pre>
  
  <p>The output is displayed below:</p>
  
  <p><a href="https://i.stack.imgur.com/iemxk.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/iemxk.png" alt="enter image description here"></a></p>
  
  <p>(Please ignore the misleading caption, that is not my concern) My question here is the 0 in the "P-Value" column. <code>kable</code> will usually put 0 here, because in this example, p = 2.3 x 10^{-36}; it is 0 when rounded, but I want to enter the exact value in the table. Is there any way to do this?</p>
