How would I convert a number such as 7.8 into a time in HH:MM? 7.8 is 7.8 hours from the start of the day, so should be shown as 07:48.

Alternatively, if you just want to display amount of hours and minutes.
duration(hours(7.8),'format','hh:mm')
ans =
duration
07:48

This is the old way to to it (before R2014b). In more recent releases, the duration approach is better.
