Default Which formula is correct for calculating times?


I built a spreadsheet to calculate hours worked; I did it over a couple
of weeks, reading and learning as I went. During the time I was doing
this, somehow I ended up with 2 different formula for calculating hours
worked...these a

=IF(N31O31,MIN(("24:00"-N31+O31)*24,7.25),MIN((O31-N31)*24,7.25))

and

=IF(N32O32,CEILING(("24:00"-N32+O32),7.25),MIN((O32-N32)*24,7.25))

where N and O are the start & finsh times respectively.

Both seem to calculate properly, but does anyone know which is the
better formula to use...of does it matter ? Thanks.
