Hello!

I have a worksheet which will be used by employees to determine their
break times in a decimal format (ex: 15 minutes = 0.25 hours). The
employees enter their particular start time and end times into two
columns and the difference is calculated. The result is then plugged
into a VLOOKUP where the decimal value is returned.

So far so good. The problem is that Excel does not always calculate one
minute to be the exact same serial number. Every once in a while it
produces a number which is close to but not exactly the same as another
minute calculated serial. Since the VLOOKUP will only return an error
on an exact match or a result which is less than the result on a
"fuzzy" match up, I need to figure out how to compare different serials
(or make them the same serial number for the VLOOKUP).

For example:

1:01 pm -1:00 pm = 0.000694444444444553
2:01 pm - 2:00 pm = 0.000694444444444442
3:01 pm - 3:00 pm = 0.000694444444443998
8:01 pm - 8:00 pm = 0.000694444444442999

All times calculated result in one minute of elapsed time, however the
serial is different which will throw an exact match completely awry.

Is there a function which will assist me in this endeavor? Any help is
greatly appreciated.

Thanks!

Mike

All you need is to use the =ROUND function to round off your results to
fewer decimal places. 6 places should be sufficient since you only
want to measure to the nearest minute.

CELL A2 = 9:00
CELL B2 = 9:10

CELL C2 = ROUND(B2-A2,6)
