Percentage calculation error?

Hi guys,
I must be missing something very basic - I can't get a simple percentage calculation to work in an applet:
float percentage = 0;
int amount,total;
amount = 4;
total = 10;
percentage = (float)((amount / total) * 100);
Instead of returning 40.0 in "percentage", this keeps returning 0.0...
What am I doing wrong? How do you calculate a percentage in Java?
Thanks!

do the type casting of either of total or amount

  • Percentage Calculation in 11g Upgrade

    upgradin to 11g issue in % cal
    The issue is as follows
    In 11g I'm calculating "ESS Rate" percenatge which is derived as below:
    ESS Rate=(ESS count/count)*100
    have casted ESS count as double and also "Count" as Int. Both the columns aggregate rule defined in the column formula is "sum"
    Edited by: 982333 on Jan 16, 2013 3:12 PM

    For more info on the columns values defined in column formula:
    ESS Rate =100*CAST(sum(CASE WHEN "Pr Audit Setup Tax Fed Fact"."Audit Oprid Nm"="- Identity".Name THEN 1 ELSE 0 END) AS double)/CAST(count(IFNULL("Pr Audit Setup Tax Fed Fact"."Audit Oprid Nm", 'NA')) AS int)
    Result obtained:
    ESS RATE| ESS Count | Count
    86.46% | 121 | 135
    while a simple calculation using calculator would clearly give you (121/135)*100= 89.63% and not 86.46%
    Can some one please help me in resolving this issue i do not see an reason for the wrong calculation of "ESS Rate" Percentage calculation.

  • Percentage Calculation for result rows

    Hi
    I have problem with percentage calculation on result rows. I have 2 KFs A and B, the result is calulated by setting 'calculate result rows as' to 'summation'.
    But in KF 'C' (which is calculated as A/B*100 ),
    Now the probles is the systen picks up original values of A and B for calculation of C in result rows.
    i.e. system picks up values of result rows for A and B for
    setting 'calculate result rows as' to 'nothing defined'.
    Any ideas on how to fix this.

  • Percentage calculation according a result

    Hi,
    I have an issue with a percentage calculation in a query.
    As rows I have Product Hierarchy 1, Product Hierarchy 2 and Material. I would like to show the sales for each material as a percentage of the result by Product Hierarchy 2 and in another colunm the percentage according the result by Product Hierarchy 1. I have used the option "Normalized according to the next level.." and it works to calculate the percentage according Product Hierarchy 2, but how can i manage to calculate the percentage according to Product Hierarchy 1( it is not the next level of the hierarchy, it would be the second next level)?
    Thanks in advance.

  • Percentage calculation based on subtotal in webi 4.0

    Hi Experts ,
    How do i calculate the % column in webi 4.0  so that % would be calculated by the amount of Primary channel / Subtotal ) in one block.
    =[Amount Of promary Channel]/Sum([Amount Of promary Channel]) In Block  - not giving correct output.
    Thanks,
    Rajib

    Hi Rajib, As per my understanding, you want to show percentage on the base of subtotal.
    that means if you set break on the Compony then percentage column should contain the percentage calculated on the basis of compony subtotal.
    like this...(just one block of break)
    then just use the simple percentage function ( =percentage(amount) ), this will automatically calculate the percentage based on subtotal.
    and if you want to show 100% in subtotal row also then you can use formula= (amount/sum(amount)),
    i think we dont need to use contex operator here.
    formula for AHW total row = amount/sum(amount)
    Let me know if this will help you,
    Thanks,

  • Crystal report 2011 percentage calculation(Urgent)

    All,
    I am working on a report which looks like the below.
    product>>>>>>> revenue>>>>>>>>> growth percentage
    a  >>>>>>>>>>>     12 >>>>>> >>>>               48%
    b >>>>>>> >>>>>>>13 >>>>>>>>                  52%
    c  >>>>>>>>>>>>>   14 >>>>>>>>>                       
    d>>>>>>>>>>>>>>  16>>>>>>>>>>>>                                     
    total         >>>>>>>   25  >>>>>                          100%
    my requirement is to calculate the individual growth percentage of a and b with the total revenue of a and b only.
    to be more specific 12 divided by 25  and then 13 divided by 25.
    i want these growth percentages in growth percentage column in my report.
    I achieved the selective summation of revenue for a and b in the report footer but i am not able to use the total revenue 25 (that i get in the report footer)  in the body of the report(detail section) for growth percentage calculation.
    I tried using shared variables and global variables but of no use.i am not able to assign the grand total in the footer to a variable in the detail section in order to calculate the growth percentage.
    Is there any easy work around to achieve this? need urgent help.
    I also tried running totals and stuff but of no use.
    Any help would be appreciated.
    Reji.
    Edited by: reji2011 on Jan 22, 2012 7:32 PM

    Hi Reji,
    I'm not sure how you've added 'a' and 'b', however, whatever way it would be, I'm sure it would be a print time formula.
    Meaning it is calculated a later stage after all the records are printed. So, you would never be able to use a value in the Report Footer or any Footer to calculate against a detail section value and show the calculation on the detail section itself.
    The way I see it, you would need to insert this report as a sub-report, just to calculate a + b, store this value in 'shared variable' and use it for calculations in the Main Report.
    So, in the sub-report, where you have your formula that calculates the addition of a and b, just create a shared variable and assign this value to it.
    Place the sub-report on the Report Header and in the Main report create a formula that calls the shared variable. You can then use this formula/variable in Main-report's calculations.
    Hope this helps!

    Hi,
    Percentage Variance (%)
    <Operand1> % <Operand2>
    This gives the percentage variance between operand 1 and operand 2. 
    Percentage Share (%A)
    <Operand1> %A <Operand2>
    This gives the percentage share of operand 1 and operand 2. It is identical to formula 100 * <Operand1> / abs(<Operand2>) , if <Operand2> is not equal to 0 and the character for u201CDivision by 0u201D if <Operand2> is equal to 0.

    Percentage Variance (%)
    <Operand1> % <Operand2>
    This gives the percentage variance between operand 1 and operand 2. It is identical to:

    Plan Sales % Actual Sales specifies the percentage difference between the plan sales and the actual sales.

    Percentage Share of Overall Result (%GT)
    %GT <Operand>
    This shows how high the percentage share is with regard to the overall result. The overall result is the outcome of aggregating the highest results level. Dynamic filters (filters that were not specified in the Query Designer) also play a role in calculating the overall result.
    Percentage Share of Query Result (%RT)
    %RT <Operand>
    This is the same as %GT.
    Unlike the process for calculating the overall result, dynamic filters are not used in the calculation of the query result. This means that the calculation always normalizes to the same value, irrespective of the filter status and the navigational state.

  • Simple calculation errors

    Does Numbers always make calculation errors?
    I have a sheet with 80.9 entered in one cell and 81.1 in another cell
    When I do a calculation of 81.1 - 80.9, the result I get is 0.199999999999989
    81.1
    80.9
    0.199999999999989
    Why is there a rounding error on numbers with 1 decimal place?
    This makes me not trust anything that Numbers does if it can't even do that!

    Mason,
    this topic has been addressed in many other threads and is a result of the way numbers are stored on a computer.  the difference between the value displayed and the correct value is 0.2 - 0.199999999999989 which is 0.000000000000011 
    all computer programs use integer of floating point representations of a number-- see this link for details:
    http://en.wikipedia.org/wiki/Single-precision_floating-point_format
    you can format the number with two digits using the cell formatter and you will see the "correct" answer:
