More info. I suspect your using

=ROUND($A$1/12,3)

For the division displayed to 3 decimal places?

if any one can help

e.g i have $100 in A1 and like to divide it by 12 and round the figure to 3
decimal place and put the result in B1 to M1 and then total of (B1:M1)in N1
the result is $99.996 how can i make it $100 without manually changing the
figures in B1:M1
