Rounding Numbers Up/Down

Daniel EDaniel E Feels At HomeRegistered Posts: 28
In one of BPP's books it gives an example of rounding down a number to one decimal place where 1.65 becomes 1.6. I was always taught that 5 as a decimal should increase the previous number. Does anyone know what the official position is on this in terms of AAT.

Many Thanks

    5 is middle ground so if you had 1.615 it would be 1.61 (two decimal places) 1.6 (one decimal place) 2 (no decimal place)

    thats the way ive done it but while doing an exam paper always stay with what the paper says

    Is it regarding V.A.T? As that is always rounded down. Other than that, normal rounding rules apply.
    Although my BPP books for NVQ2 last year was full of dreadful errors, so this could be just as likely!

    Not specifically, just decimal figures in general.

    Then i would guess that the book is wrong. It wouldn't surprise me.

    You won't lose any marks rounding up or down a five.

    Agreed.

    Strictly speaking, a decimal of 5 should be rounded up, but you can round up or down for the exams. They will accept either as being correct.

    It's not a maths exam. Its an exam testing you knowledge, understanding and competence with accounting entries/equations and preparing accounts.

    Yes you should normally round '5's up. But this specifically says round down to one decimal place. Did this come from the question/example directly?

    Round '5's up unless you are specifically asked to round down.

    So you don't think it's that important then?

    no you wont lose point on your roundings as long as you show your workings

    Excel automatically treats rounding as:

    1.0, 1.1, 1.2, 1.3, & 1.4 are rounded down to 1 (five counts)

    1.5, 1.6, 1.7, 1.8 & 1.9 are rounded up to 2 (five counts)

    Thats what I've always done, and I'll keep rounding up 1.5 regardless of what that book says.

    Not in the grand scheme of things.

    I've been told that it doesnt matter what you do, as long as your consistent. So if you decide to always round up for .5 then fine, but dont chop and change and they dont care.

    float

    float f = 10.123456F;
    float fc = (float)Math.Round(f * 100f) / 100f;

    Double

    Double d = 100.123456;
    Double dc = Math.Round((Double)d, 2);

    Decimal

    decimal d = 100.123456M;
    decimal dc = Math.Round(d, 2);
