    Question how to make excel multiply numbers with 3 decimals?

    Ok, my english is lousy but i will try to explain somehow.
    This is the calculation I have made in excel
    1152,31*0,15=172,85
    And this is one made with ancient accounting calculator my boss uses:
    1152,31*0,15=172,84

    You get the picture?
    So, I work with taxes and I have loads of calculation to do. Is there any way to set up excel so it can calculate numbers like this(automatically with two decimals) because my boss believes only in his ancient calculator...
    If anyone knows, please hurry, I have a deadline in 2 days...

    That number is rounded down from 172,8465....

    Excel has a Rounddown() function...

    =Rounddown(number,decimals)

    e.g. =Rounddown(1152,31*0,15;2)

    Try:

    =ROUNDDOWN(IF(H5<540;0;IF(G5<9000;((G5-3600)*0,25);(5400*0,25)));2)

    because my boss believes only in his ancient calculator...
    get him to do it manually! then he will see the calculator is erronous.
    1152.31*0.15
    =115231 *10^-2 * 15*10^-2
    =115231 *15 *10^-2*10^-2
    =115231 *15 *10^-4

    115231
    x 15

    -------
    576155
    1152310
    -----------
    1728465


    1728465 x 10^-4 =172.8465
