PE,
I assume the fractional day values are appearing in the Duration field
instead of a customized field (e.g. Duration1). Depending on your
intent, one way to eliminate fractional days is to modify the schedule
so that all tasks start and finish at the beginning and end of normal
work days. This can either be done manually or through VBA code. However
this may neither be convenient nor desirable. The next suggestion is to
create a custom field that takes the Duration field and applies a
rounding function.
Hope this helps.
