    auto sum yields wrong number

    I've calculated this about 10 times but there is something very very wrong here.

    When I make the sum of column J manually, I get 1131 while Excel feels it should be 1130. Is this a computer error or am I going mad

    Please FORMAT CELLS of column J as number with two decimal places. You will see that these numbers are not rounded.

    Format numbers with more deicmal places and you'll see those number are rounded. Now try to sumarise number with 3 decimapl places and see is there any difference and let us know
    Never use Merged Cells in Excel

    I hope I've understood correctly but I still can't see what's wrong (it seems to round up just fine). New formatting attached

    You just like to tortch us

    1129,959

    And excel said 1129,958

    Now take more dicimal places and you'll get more correct solution (because of those divided by 3 and 6 numbers)

    Ow I was looking at it the wrong way. Feel free to hurl a brick now, lol. in my defense I am dyslectic so it's a real torture.

    That the reason I don't use decimals most of the time. Doesn't always work out
