We use 3 letter codes (A, S, P) for leave taken by an employee. The number
of hours is entered as H:MM, then the letter leave code (e.g., 1.45A, 2.30S,
4:15P). I need a formula to add the total number of hours in each row for
the three letter codes. I have spent hours searching for formulas online and
am not sure which functions to use (SUMIF, SUM, etc.)

I also need a formula that would convert the a total number of leave hours
e.g., 147.70=148.10, 1233.89=1234.29, 602.97=603.37. Any help would be
greatly appreciated.
