EPoch calculating datetime fractional difference

Trying to calculate the difference in time between an assignment start time and end time with the answer formatted in total hours and any fraction thereof.

So, if I worked 9/14/2016 13:00:00 till 9/14/2016 18:00:00 the 'Total Time Worked' equates to 5 hours.

Yet, if there was a fractional time 9/14/2016 13:00:00 till 9/14/2016 18:31:00 'Total Time Worked' equates to 5.52 hours


I have attached the XLSX form with my calculations.  The row starts at A11 through A14.  My current formula of:


int((${end_date_time}-${start_date_time}) div(1000*48*60)) 


cannot produce a fractional answer.  I have reworked it numerous times... This link shows it can be done, yet its beyond my ability.


And looked at Dates and Times in Survey123 for ArcGIS as well...
