title: If I copy a float to another variable, will they be equal?
body: <p>I know that using <code>==</code> to check equality of floating-point variables is not a good way. But I just want to know that with the following statements:</p>
  
  <pre class="lang-cpp prettyprint-override"><code>float x = ...
  
  float y = x;
  
  assert(y == x)
  </code></pre>
  
  <p>Since <code>y</code> is copied from <code>x</code>, will the assertion be true?</p>
