Mod Function Works Wrong

Dec 28, 2006

I was trying to explain modulus to someone and they wanted to know why you can "flip" symbols mod(-6,7) = 1 in Excel. So I got to explaining that -6 Mod 7 is the same as -6-(|-6/7|)*7 which is how you get 1.

And that's when I realized... |-6/7| = 0 not -1. Then I looked in VBA and sure enough -6 mod 7 = -6. Apparently the problem boils down to the Integer conversion. Excel is performing the integer coversion by rounding down (INT) wheras VBA appears to be using CINT.

So here is how it work out in excel:
-6-(|-6/7|)*7
-6-(|-0.857142857|)*7
-6-(-1)*7
-6--7
-6+7=1

But in VBA you get
-6-(|-6/7|)*7
-6-(|-0.857142857|)*7
-6-(0)*7
-6-0=-6

Excel 2010 :: VBA Sheets Copy Function Works But Then Jumps To Beginning Of Function

Apr 8, 2014

I'm having trouble using the worksheet copy command in a VBA subroutine. I have the following line in my code:

[Code] ........

When I step through my code and execute this line, the sheet is copied as expected and put in the correct place, but then instead of the next line of code being highlighted, the pointer jumps to the first line of a function (in a different module) in my code.

IRR Function Is Returning The Wrong Value

Nov 7, 2008

I'm trying to figure out an Internal Rate of Return for a spreadsheet. The answer is supposed to be: 29.42% however I'm getting 25.94%. Does anyone know what I'm doing wrong in my IRR function on the Profitability worksheet? I'm currently using Excel 2007 by the way.

Rounding Function Works On 1 PC But Not Another

Dec 1, 2008

I have a very simple spreadsheet that I use for preparing quotations. It was created on my PC at home and includes a simple roundup function (=ROUNDUP((F199*G199)+F199 2) ).

I now use this spreadsheet on my PC at the office and the function works perfectly well but if I try to edit it, or create a similar rounding fx, on my office PC I keep getting the error message "You've entered too few arguments for this function".

I've tried using the Help Menu in Excel but even if I copy one of the formulas from the Help Menu into the spreadsheet I still get the error message. The 2 versions of Excel are the same (2003). I tried inserting a ',' and a ';' in front of the '2' but this has also not helped.

I have attached a sample of the offending spreadsheet. The rounding function is in column "B"

IF Function Only Works With 7 Different Selections

Aug 26, 2002

I’m trying to do the following IF function but as far I can tell IF only works with 7 different selections.

Cell B2 contains the numbers I through 8
Cell D2 contains a pre-calculated number (e.g. 53.012)
Cell F2 is the cell that I need an IF function or something similar – the function would be as follows
=IF(B2=1,D2*1.000)
=IF(B2=2,D2*1.00057)
=IF(B2=3,D2*1.00171)
=IF(B2=4,D2*1.002281)
=IF(B2=5,D2*1.003421)
=IF(B2=6,D2*1.003991)
=IF(B2=7,D2*1.004215)
=IF(B2=8,D2*1.004538)

Int Function Only Works With Double

Aug 15, 2006

If you run the Int function on a product of two variables, it will return a different (wrong) result if the variables are both defined as single:

Sub roundingtest()
Dim a As single
Dim b As single
Dim cases As Integer
a = 18200
b = 0.01
cases = Int(a * b)
Debug.Print cases;
End Sub

this returns 181 instead of 182. If you define one of the variables as double, then it works fine. Is it just me?

Anyway, I found it to be quite useful, as i was trying to get a function to round to the first higher integer - as opposed to the first lower. so
182.1 -> 183
182.9 ->183
182 ->182

So weirdly enough, int(a*b)+1 does the trick! Of course if a or b is defined as a double, then it all goes to 182. So without any IFs, this works real nice!

Match Function Given Wrong Position

May 14, 2009

I have the following equation programed in Excel, (see file attached). I do not understand while the match funstion is not working the lookup value is the on in cell N1 the array is from B1:F1. The return value should be 3 but I get #NA instead at the begining I was thinking that the values were different but then I compared cell =D1=N1 and the result was TRUE, meaning that they are equal

Wrong DataType Parsed Into Function

Jul 28, 2013

I have a function that starts as follows:

Function Timings(StartTime As Double, EndTime As Double, Times As Range, Calc As Long)

StartTime will refer to a cell in Column A that holds a date and time EndTime will refer to a cell in Column B that holds a date and time Times is the range of cells that hold times of the day I am testing against. The cells are within a range defined called Hours. Calc refers to different criteria that I am testing again. This is a number list between 1 to 5.

The function works well if the cell that StartTime or EndTime refer to cell values that are date/time. If the data is anything different, I get a #VALUE error such as if the cell contents is text. I tried to trap the error to see if the data inputted in the cell is not date/time and thus cannot be converted to a Double but it always throughs up #VALUE and the function seems as though it fails when it . Is there anyway to trap the error of wrong data type in the first the first few lines of code in the function?

Example

Column A Column B Column C Formula
05/01/2013 12:00 06/01/2013 09:00 =Timings(A1,B1,Hours, 1)
25/02/2013 15:00 30/02/2013 14:30 =Timings(A2,B2,Hours, 1)
03/01/2013 16:00 abc =Timings(A3,B3,Hours, 1)

Row 2 will return #VALUE becuase 30/02/2013 14:30 is an invalid date (30th Feb does not exist so Excel seems to pickup as text)

Row 3 will return #VALUE because it is text and cannot be converted to a double data type

Today Function Works Strange

Aug 24, 2009

I have a column, where i want to calculate the difference between today and another date/or viceversa. The problem is, that in the first two cells, it calculates it well, but then, it shows #VALUE and when I press to see the "calculations steps" , it shows "29/09/2009"-40049. It turns the today function into a number. Why?

Function Works But Get Runtime Error 13?

May 20, 2014

This is a function to add the ascii values of a string to give a single value. Initially I wrote this as a Sub routine and it worked fine, but when making it into a function, I get this error. From a little research it appears that you can not use a string as an argument for a function call, yet that defeats the object of this particular function.

The intention of this function is that it works on a name in a given cell and the value (an integer) that is produced is then displayed in another cell, or if using it as a formula, the cell the formula is in.

I simple wrote the work "Hello" in cell A1 the ascii values of these added ignoring any spaces give 500 which is correct.

INDEX Function Works In Cell But Not In VBA

Mar 25, 2013

I've been working on a payroll program for my small biz. I'm close to done BUT...

When I use the Index Match function in a cell it works great. However I need to copy it down a column to work for pay periods going forward. When I copy it down of course it puts zeros or N/A.

Columns:

Gross Fed FICA Medicare State Net
F G H I J K

Gross is user input. FICA Medicare State and Net are simply calculated on the sheet. But to get Fed Income tax I use the Index Match function and it works perfectly. The rows increment properly with each new user input.

Code:

=INDEX(SingleWH!C$6:M$140,MATCH(G7,SingleWH!A$6:A$140,1),MATCH(E$1,SingleWH!C$4:M$4,0))

This is the code in Column F. You can see where it uses the result in Column G to look for a value in sheets("SingleWH").

My question: Fed Income tax is dependent on what the Gross is in order to look up the tables with the Index Match function. How do I get the result of the function into column G? Can I increment up Column G and ignore the zeros that dragging the function down G creates?

Function Works In VBA But Does Not Work Inside Worksheets

Jun 21, 2008

i have written a code in VBA to interpolate the value of Y0 corresponding to X0 using a set of (X,Y) points. (I have written this in module1) . This function works when i call it through a Sub or another Function in VBA. but it does not work when I try to use it as a function in my excel worksheets (when I type : =interpolate(A1:A10,B1:B10,30) .... 30 is an arbitrary value). in this case I get #value! error

Countif Function In A Macro: SUM And COUNTA Works

Jan 27, 2009

I'm using the SUM, COUNTA and COUNTIF functions in a macro. The SUM and COUNTA works but the COUNTIF function does not return results.

Sub B_Test()
Dim myRange
Dim Results
Dim Run As Long
myRange = Workbooks(1).Worksheets("Master").Range("S6", Range("S6").End(xlDown))
Range("M3") = Application.WorksheetFunction.Sum(myRange)
myRange = Workbooks(1).Worksheets("Master").Range("D6", Range("D6").End(xlDown))
Range("D3") = Application.WorksheetFunction.CountA(myRange)
End Sub

I have tried countless ways to rewrite the COUNTIF line with no results or compiler errors returned. Originally had problems with the SUM and COUNTIF function and found that column formating was the problem. After clearing all column formats, the SUM function promptly began working but the COUNTIF keeps eluding all my efforts. The column which the COUNTIF is pointed to contains values of 0 to 500. Only values greater than 0 are to be counted.

Counts The Number Of Hours That This Person Works & Lookup Function

Jan 25, 2008

I'm trying to create a work Rota and I'm having a bit of a problem with a certain section. In Worksheet 1 I have the following headings:

Cell A - Name
Cell B - Monday
Cell C - Tuesday
Cell D - Wednesday
etc

Under these headings is each member of staff and the hours they work, IE L (Late), E (Early), SD (Short Day) etc. In the final Column, it counts the number of hours that this person works (Early is 7.5). In Rows 46, there is a section here to work out how many people are working earlys, which is where I have the problem.

The hours are worked out by doing a lookup function on the cell that says E, L etc and goes to a CODES sheet and pulls the value of that letter. What I am wanting to do is lookup that Letter, which and look in the cell next to it and count how many people would be on an early etc.

Text To Columns Function Picks Wrong Number Format After Conversion

Jun 16, 2014

Using the text to columns option on a comma separated file in csv format leads to the right preview in the text to columns wizard.

The column titled "ATTIC: Zone ..." shows the desired format in the preview window. Please look at the screenshot 1.jpg.

After pushing the finish button to obtain the result the number format gets suddenly changed and differs from the preview.

Again check for the "ATTIC: Zone ..." column as reference: 2.jpg

Is there a menu where one can look up, or specify how to format data to force the right comma placement? What settings might be wrong?

IF Blank Or If Not Blank Function That Works With Adjacent Cell With Formula In It?

How To Make Function That Works On One Line Work On Multiple Line

VLOOKUP Returning Wrong Value?

Jul 3, 2013

I am trying to use the Vlookup function to return State name based on the corresponding state code.

I have the list of State along with the Codes in adjacent sheet, arranged in ascending order. I am using the Vlookup function to list the State name based on the State code.

Vlookup function: Vlookup(A4,Sheet2.A2:B51,1)

This function returns me a wrong value. It gives "Arkansas" for the state code "AZ", when it should be Arkansas.

Also, if I add "FALSE" as a 4th argument, it returns "#N/A".

Wrong Dates In Database

Apr 18, 2014

When copying data from a website to excel, excel recognizes the dates wrongly.

About half of the dates he sees as: DD/MM/YYYY, while it should be: nothing/MM/DD.

For example: The cell contains the date: 01/04/2029 (The first of April, 2029)

While it should actually be: 04/29 (The 29th of April, no year!)

For all dates it starts with the 1, followed by a month, followed by a year (which consists of the year 2000 + the actual day), which is totally wrong.

About the other half of the cells, it just contains text with the month and the day (which are correct), but excel doesn't recognize this as a day.

For example: The cell contains the text: June 12

When I set the cell format to date (or any other format for that matter), nothing happens, so excel does not see this as a date.

References Goes Wrong After Sorting

Feb 18, 2010

I have a problem with my references when sorting in excel. I have been searching for the problem, but did not found a useful solution.
I'm using excel 2003.

Let me try to explain my problem with a simple exampel.

I have a column with numbers and one with formulas pointing at these.
A B
2 =A1
4 =A2
3 =A3

Now I want to sort column A, and the column B should keep pointing at the original number. So I want this:
A B
2 =A1
3 =A3
4 =A2

But I get this:
A B
2 =A1
3 =A2
4 =A3

This output is what I would expect if I used absolut reference($).

Using offset(B1;0;-1) will work, but I cannot use this, since I will add/delete rows and the reference is not neccessarily next to it. Plus it can be a rather large sheet.

I cannot use dynamically name definition either, because it is intended for other users, and this will be too much work for them. What I basically need is a simple formula they can enter.

My sorting is done via a VBA macro, so if there is anything I can do through macro/VBA that will be okay as well, since I can do this without the user seeing it.
