title: Converting a float into a timespan
body: <p>Is there a simple way to take a <code>float</code> value representing fractional hours and convert them into a <code>TimeSpan</code> object and visa versa? For example:</p>
  
  <pre><code>float oneAndAHalfHours = 1.5f;
  float twoHours = 2f;
  float threeHoursAndFifteenMinutes = 3.25f;
  float oneDayAndTwoHoursAndFortyFiveMinutes = 26.75f;
  
  TimeSpan myTimeSpan = ConvertToTimeSpan(oneAndAHalfHours); // Should return a TimeSpan Object
  </code></pre>
  
  <p>Any ideas?</p>
