title: Will converting a string to a double equal the literal double?
body: <p>For example:</p>
  
  <pre><code>assert(atof("1.2") == 1.2);
  </code></pre>
  
  <p>regardless of what float is used?</p>
  
  <p>I understand that the floating point precision isn't exact, but it is precisely inexact so does the rounding to binary produce the exact same double?</p>
