title: Format minutes into hours and minutes as a decimal number in T-SQL
body: <p>Is there a clean and simple method of formatting an integer which is a count of a whole number of minutes into a decimal representation of hours and minutes. It's a great shame that there is not such thing as a Timespan in T-SQL to support this. </p>
  
  <p>Just to be clear what I mean by this is if I have 70 minutes, I want to covert it into a representation of 1 hour and 10 minutes i.e. <code>1.10</code>. I'll also want to keep it as a varchar or something to ensure that the trailing zero is kept in place.</p>
  
  <p>Is there anyway that this could be created as a custom function in SQL so that it can be resused from different queries?</p>
