rounding in quarter increments

[toastnbutter]

I am trying to find the best formula to demonstrate the length of time
it takes to perform tasks and then round them to quarter day
increments. For example, a task takes 10 hours to perform I need a
formula that will take the 10 hours and display 1.25 (assuming an 8
hour work day).

By the same token though if it is 10.5 hours it should roundup to 1.5
and not display 1.3.

Any help would be greatly appreciated.

One way:

If your times are in XL time format (e.g., 10:00), then


=CEILING(D30*3,0.25)

(The 3 comes from 8 hours being 1/3 of a day, so hours need to be
multiplied by 3).

If instead your times are entered as number of hours (e.g., 10.0, 10.5),
then

=CEILING(A1/8,0.25)

Hi,

if total hours number is in [A1], then try this:

1) for normal rounding

=ROUND(A1/8/0.25,0)*0.25

2) for rounding up (which is what your example suggests)

=ROUNDUP(A1/8/0.25,0)*0.25
=CEILING(A1/8/0.25,1)*0.25

3) for rounding down

=ROUNDDOWN(A1/8/0.25,0)*0.25
=INT(A1/8/0.25)*0.25
=TRUNC(A1/8/0.25)*0.25
=FLOOR(A1/8/0.25,1)*0.25

you can also use the MROUND function, which is part of the ATP (Analysis
ToolPack), but I never recommend those formulas for compatipility reasons.
