title: Store NaN values in SQLite database
body: <p>I'd like to insert NaN values into SQLite database. </p>
  
  <p>I have Ent table with Id, StringColumn and DoubleColumn (not nullable) and I try use the following SQL statement:</p>
  
  <pre><code>INSERT INTO Ent (Id, StringColumn, DoubleColumn) VALUES (1, 'NaN test', ????)
  </code></pre>
  
  <p>I don't know what to put in place of '????' to have NaN stored.</p>
  
  <p>I'm accessing the database using System.Data.SQLite - maybe this also matters?</p>
