Hi Bernard,
Thanks for your idea. Problems arised was nothing related to the decimal
places because I extract the figure before decimal for compariation.

Are you comparing real numbers (numbers with decimal places)?; if so, it is
possible they display the same but are very slightly different.
Try =if(ABS(A1-A2)<1E-10,"yes","no")

I have two cells with values which were macro auto copied from other cells
by
copy - paste special - value, I have a =if(A1=A2,"yes","no") formula in
third
cell to compare these two cells. From time to time the output of formula
gives inccorrect answer, but if I copy the first cell to the second cell
again manually using copy - paste function, the third cell gives the right
answer. Any idea why and how to correct this please?
