title: Convert byte slice "[]uint8" to float64 in GoLang
body: <p>I'm trying to convert a <code>[]uint8</code> byte slice into a <code>float64</code> in GoLang.  I can't find a solution for this issue online.  I've seen suggestions of converting to a string first and then to a <code>float64</code> but this doesn't seem to work, it loses it's value and I end up with zeroes.</p>
  
  <p>Example:</p>
  
  <pre><code>metric.Value, _ = strconv.ParseFloat(string(column.Value), 64)
  </code></pre>
  
  <p>And it doesn't work...</p>
