decimal places on numbers
I have calculated various percentages which give me more than two decimal places. I have kept the cells of these results at 2 decimal places. I have then used these various results and added them which have given me an error in the sum. I assume this is because the numbers I have added although seen as 2 decimal places have more than two decimal places. This means that my sum is various numbers off the right answer. How can I fix this problem?
Say 10.10 + 10.10 + 10.10 should SUM 30.30
But my answer comes to 30.29 as the 10.10 are not exactly 10.10 but as my cells are at 2 decimal places this is what I can see.
Hope I have explained myself.
Thanks for the help
