title: Can Time.deltaTime reach 0?
body: <p>Here is sample of short code </p>
  
  <pre><code>    if (timer &lt; 0)
      {
          timer = cooldown;
      }
      else if (timer &gt; 0)
      {
          timer -= Time.deltaTime;
      }
      else if (timer == 0)
      {
          print(0);
      }
  </code></pre>
  
  <p>and may be <code>cooldown = 1</code>  </p>
  
  <p>My question is easy: 
  is it possible to reach state <code>timer == 0</code> ? 
  I mean theoretically is there possibility of hitting precisely 0 with <code>Time.deltaTime</code> ? I know it sounds stupid considering size of <code>float</code> but still im pretty interested if this scenario could happen.</p>
