Rounding to nearest integer

[Guest]

I have searched many many places and still cannot find my answer. I have a
worksheet that I am calculating workers minutes allowed - I used
=SUM(B322:B323) which is correct, then I have to total hours per day - I need
to total using the number obtained from Min Allowed divided by 60 then
calulated to the nearest half
ex: 7.1, 7.2, 7.3,7.4 = 7.5 and/or 7.6, 7.7, 7.8, 7.9 = 8

I need the formula for rounding to the nearest half hour

Any help is much appreciated as I'm really lost

=ceiling(your number ,0.5)

To round to units of, say, 4 we can use =ROUND(A1/4,0)*4
So you could use =ROUND(B1/TIME(0,30,0),0)*TIME(0,30,0) if B1 has to total
time OR
=ROUND(SUM(range_with_times)/TIME(0,30,0),0)*TIME(0,30,0) to replace your
SUM formula
best wishes

Also =ROUND(B2*48,0)/48
This works since time is a fraction of a day (24 hours), so 48 gives
fractions of half-hours. Hope you see what I'm getting at!
