Unwanted Rounding In Math
Jun 24, 2006
I have a spreadsheet acting as a check register. In looking through the over 2300 entries, I am getting "odd" rounding issues. I have attached a small piece of the worksheet to demonstrate this quirkiness. As you can see, I am adding numbers out to two decimal places (which should result in two decimal place answers). The result for 11/11/2002 has become a more complex number. And, the result for 11/14/2002 goes back to two decimal places.
I have upgraded my office suite since 2002. Could that be an issue? I prefer not to have to "force" the rounding =round(result,2) to solve the problem.

I am trying to round similar to Banker's Rounding or Scientific Rounding but I can't find a consistent formula that works perfect with decimals.
Using three decimal places for all the samples, I can get 0.0785 to round to 0.078 but 0.1785 wants to round to 0.179 instead of staying 0.078. Or 0.0005 will round to 0 but 0.5115 wants to round to 0.511 instead of 0.512.
Here is a list of sample numbers along with desired results:
.0785 should be .078
.5115 should be .512
.5035 should be .504
.0005 should be 0
.0025 should be .002
.0194 should be .019
.0195 should be .02
.0135 should be .014
.0115 should be .012
.8115 should be .812
I cannot find a formula which gives me all of these results. Here is a list of the formulas I have tried so far (NOTE: cell A2 is the working cell in my worksheet where I enter the number to be rounded)
1) =MROUND(A2,0.001)
3) =ROUND(A2,3)
4) =IF(ISERROR(IF(MOD(MID(A2,4,1),2)=1,CEILING(A2,0.001),FLOOR(A2,0.001))),0,IF(MOD(MID(A2,4,1),2)=1,CEILING(A2,0.001),FLOO R(A2,0.001)))
5) =EVEN(A2)
6) =ROUNDUP(A2,3)
7) =ROUNDDOWN(A2,3)

i am trying to make an excel sheet that does calculations to help drydock a submarine....
docking math is used and it works as follows:
6-11-7
6-11-7+
6-11-7++
6 is feet
11 is inches
7 is 1/8ths
+'s are 1/16ths
so i want to be able to have a list of set measurements like above and then have one set measurement be subtracted from the list. like
12-4-6+
13-5-4
14-2-4
and have 6-2-5+ be subtracted from all of the above and be displayed on a second page. I have slammed my head against the wall for about 3 days now and i am a excel newbie. so if i messed up somewhere or anyone could help i would greatly be appreciate it.

I am trying to create a macro that will do some basic math using J, I as referencing.
Sub Table()
Dim Temp
J = 2
I = 1
For Temp = 1 To Question
Cells(J + 35, I).Formula = (Cells(J, I + 2) + Cells(J, I + 2) * Cells(J, I + 3) - Cells(J, I + 4))
J = J + 1
Next
End Sub
how do I get the math to work without the R1C1 referencing?

Trying to compute annual change I've always used the formula "(b1-a1)/a1" - where b1 is the current year, a1 is the prior year. I've been asked to compute average annual change over a number of years and thought simply by using the above for each year and then taking the average of all these, I'd be ok. I recently found a formula as follows: "(y2/y1)^(1/n)-1", where y2 is current year, y1 is 1st year I have data, n = the number of changes.

How do I correct to make conditonal formula with number values ?
My main worksheet has at leat 24 columns and as many as 30 rows, all have
numbered values. Rows are defined names.
I want to get average values when at least 2 conditions have certain values.
I tried =SUM(IF(AND(MapKpa:MapKpa=40),(RPM:RPM=1000),grmcyc:grmcyc))
and answer given is really total of all 30,000 row values for grmcyc and not
when mapkpa values = 40 and RPM = 1000.
Also best would be if the conditions allow lets say when Mapkpa is between
40 and 45 and RPMs between 1000 and 1500 to have a window of grmcyc average
I used Sum but really want an average of grmcyc when Mapkpa and RPM meet the
conditions so I can build a results table of what the grmcyc average value
was from 20 to 105 KPA in 5 KPA windows along with smaller RPM ranges.

I have a user that wants me to calculate a value for x. The user will input the variables a and b into this equation: b/a = .0231x * EXP(.0439*x). The user insists that the solution to this problem must be arrived iteratively, honing in on the correct answer. Is that right? It looks to me that surely there is a way to solve this mathematically.

Let's say in cell A1 I have something like "10-25" or "4+4". I want to keep A1 just like that, but I would like to solve the arithmetic in A1, in cell B1. So B1 would need a formula that gives the answer "-15" or "8". How can I do this with large data sets?

I am looking for the easiest way for my worksheet to perform the following:
My 1st sheet (Sheet1) has columns A-C
In Column "A" there is a Cust # call it "P200"
In column "B" I have an invoice amount of $500.00
In column "C" -In this case, I need this field to calculate 15% of the amount in column "B"....and return the result of $75.00 (however, this 15% figure will vary based on data looked up in (Sheet2)
ie... in (Sheet2)
Column "A" will list all cust #'s that my company has - A1=P100, A2=P105, A3=P125, A4=P127, A5=P200 etc....
Column "B" has each respective discount amount for that customer by %... B1=10%, B2=10%, B3=12%, B4=20%, B5=15%
So the macro I need for (Sheet1- column C) will need to search "Sheet2" column "A" to find the "P200" out of the long list and then take the corresponding % amount in column "B" (in this case it's 15%) and use this figure in (Sheet 1) to perform the calc.

Given a list of numbers and a list of 'allowable' operators, come up with a specific total. ("The numbers game" on countdown on BBC2.... ooooh Carol Voderman)
For example, given the numbers 1, 3, 4 and 5 with valid operators +, -, /, * come up with a solution equal to 15. All numbers must be used once only. Use operators as often as required. The specific example above was given to me and I personally think its not solvable (might be a practical joke). But I am wondering is it possible to prove this through assertions or develop an algorithm to solve such puzzles. I can get 14 and 16, but not 15....

attempting to utilize the powers of Excel to generate a math worksheet for my children. I have no experience with macros and I have only used the basic functions and formulae.
Basically I need assistance in designing a worksheet where I can input the number of problems I want displayed, the type of problems (add or minus), and the number ranges for the values. With a subtraction problem, I want the formula to make certain the top number is not lower than the bottom number. Also, I would prefer that the worksheet maker does not generate duplicate problems. Once generated, I have the option to print the results for the kids to take with them or sit on the computer and enter the values - whereby Excel will instantly turn color the answer cell green for a correct answer, and red for an incorrect answer.

Assume A1=25 and A2 = 35.
I typed, in cell A3: =A1+A2 which returns: 60.
Is there a way to present, in a single cell, instead of the formula references - something like: =25+35 as TEXT ?
(Any change in A1 and/or A2 will be reflected in the presentation of those two values
I checked some add-ins functions, like "MoreFunc" etc, and INDIRECT - but no results.

I am trying to put together a basic sheet with what I think is basic math, however, the multiplication does not seem to be working properly.
Field 1 is land value, field 2 is total acres. The math I have in field 3 is to give me a value per acre. Here is that formula: =Sum(B3/C3)
I have set the field to a number field with two decimal places.
Field 4 is Total Dry Acres field 4 is calculated to give total value for dry acres (here is where I am having problems) Here is the formula: =Sum(D3*E3)
Here are the numbers: Field 1 = 218702 Field 2: 1536.51 Field 3 (calculated): 142.34 Field 4: 1171.75 Field 5: 166791.54
It all looks good on the spreadsheet, however the field 5 number is not correct.
Break it out on a calculator: 218702 / 1536.51 = 142.34 (rounded)
Now 142.34 * 1171.81 = 166795.44
so working on the calculator, there is a difference of 3.69 between the two.

I am looking for some examples of simple math (Adding, Subtracting, Dividing & Multiplying) using Text box values in a userform.
I have 6 textboxes. 3 of them for data entry and 3 of them for calculating from the other three.
I am not looking to work of any worksheet, it must be done in the user form.

I am having an issue with Excel not adding three numbers correctly.
C10 = .82
C11 = .18
C12 = .70
C14 = Sum(C10:C12)
I also tried C10 + C11 + C12
Excel keeps telling me the answer is 1.69!

I have Three different combinations which are in cell A & B, These combinations are with similar signs as in A1=2- & B1 = 2- (& A1 = 2+, B1=2+). Then I have numbers with no signs which A1 =2 B1= 2. My approach is to limit to these and these combinations only and use a formula which is uniformally applied on these combination. I want A1 and B1 to take only like signs like -- or ++ or without any sign. The rest shd be ignored. IS there a way of sorting two columns which have different combinations liek -- or ++ or -+ into a area where u can apply a particular formula? Hence first i take a number and move signs on the left and then apply this
IF A7 = 2- . B7 = 3- THEN
IF(OR(RIGHT(TRIM(B7),1)="-",RIGHT(TRIM(B7),1)=" ",RIGHT(TRIM(B7),1)="+"),LEFT(TRIM(B7),LEN(TRIM(B7))-1)*3,B7*3)

We make many graphs using XYscatter charts with lots of data points using Excel 2003 with the horizontal scale properly scaled as frequency. I have been asked to label that axis in some way as period (=1/frequency) without changing the scaling for the data plot. Is there a suitable way to do this? It would be OK to just change the axis numbers to 1/frequency computed from them automatically. Is Excel 2010 any easier for this?

Each week I import some data into my workbook (its financial-imports stock names, identiy codes and stock type). I've added a formula which calculates the credit ratings of each stock type, and then conditional formatting to highlight any credit ratings which are less than my required rating.
Further to this I need to get rid off all the rows which which have an stock type "No Asset Class". I cant use auto-filter because there are too many other stock types which I need to be included.

While running my program, the code is halted and my code is displayed as if I had set a breakpoint. The next line of code to execute is highlighted in yellow. However there is no maroon colored background around the code. I have no breakpoint set on this line. Is there any reason my program is behaving this way? Is there anything I can do to get rid of this bug?
