# 2 Digit Number Combination

Jan 26, 2009

I'm trying to figure out how to setup a worksheet to find the most common 2 digit numbers going vertically from the bottom(cold) to the top(hot) it would consist of 90 digits 0 thru 9

it would look like this

4 0 3 9 0 4 3 3 2
9 2 5 6 5 6 9 6 6
8 9 9 3 1 0 2 9 8
1 6 7 5 9 9 8 2 5
2 7 2 2 2 8 5 1 3
0 1 4 7 4 7 6 0 9
3 5 6 4 3 3 0 4 4
7 8 8 1 8 5 7 8 7
5 4 1 8 6 1 1 5 1
6 3 0 0 7 2 4 7 0

each vertical line would be considered weeks 9 thru 1. week 9 would be the first vertical line of digits on the left. it could also contain the most common 2 digits horizontally. Both 2 digit values would be color coded ex. blue equals most common 2 digit horizontally and green equals vertically. I would also like to color code the most common 2 digit value diagonally as long as it is the most common of either the vertical or horizontal 2 digit. Each number is seperate on the worksheet they would not be pairs. im using excell 2003.

## Seperate 2 Digit Number Into 2 Single Digit Numbers

Apr 3, 2008

I know you can take a number from one cell and combine it with number from another cell and make it one number. What I need to do is the reverse. Take a two digit number in a cell and separate it into single digits in two cells. If you have the number 50 in a cell, then is there a formula that will take the 5 and put it in cell and take the 0 and put it in the cell beside it?

## Remove The Last Digit From Each Number, Turning It Into A 5 Digit Number

Mar 2, 2009

I have a column of 6 digit numbers in excel, and I need to remove the last digit from each number, turning it into a 5 digit number. No rounding, just simply remove the last digit. Each number is different. Does anyone know how to quickly and efficiently remove the last digit from each number? I can convert to alphanumeric string if need be...

## Check Digit For 8 Digit Number

Jun 13, 2014

How to calculate a check digit in excel. The details to calculate this are as follows:

All variables in the calculation are positive integers.

We take each integer of the pro number and multiply it by a value and sum them to get a total.

An Example: 8 Digit Pro Number: 66988757
Pro Number: 6 6 9 8 8 7 5 7
Position in the Pro Number: 1 2 3 4 5 6 7 8
Multiply each digit in the pro number by (10-position) in the number, to achieve a sum.

Using our example pro again:
6*(10-1) + 6*(10-2) + 9*(10-3) + 8*(10-4) + 8*(10-5) + 7*(10-6) + 5*(10-7) + 7*(10-8)
6*9 + 6*8 + 9*7 + 8*6 + 8*5 + 7*4 + 5*3 + 7*2
54+ 48+ 63+48+40+28+15+14 = 310
Take the Sum of the previous calculation and divide it by 11
310/11 = 28

(Actually, it's 28.181818, but since we're working with integers, we truncate everything behind the decimal).

Figure a remainder by multiplying the quotient by 11 and subtracting from the sum.
Remainder = 310 - (28*11) ---> Remainder = 310 - 308 ----> Remainder = 2
Check Digit = 11- Remainder
Check Digit = 11 - 2 ---> Check Digit = 9
Note: if the check digit is 10 or 11, need to subtract 10 from the Check Digit.

## Decrease Letter And Number Combination Code By Number

Dec 21, 2012

I have letter and number combination code in two collumns and they differ for 10.000 numbers:

BAM98314
BAM88314
BAM90000
BAM80000

As you can see the left code is for 10000 numbers higher. the letters are allways the same. In the event that this isn't so, if difference between codes in same row is more or less than 10000 numbers. I was thinking on making conditional formating so the cells with wrong difference would be marked red, but I do not know how to make formula for this difference.

## Counting The Number Of Times A Multi Digit Number Appears

Nov 22, 2007

I've tried everything I know (which isnt that much to be honest. lol). Ive tried the frequency formula but that doesn't work the way I want it - I think its probably the wrong formula to use. I've also tried a pivot table but they always vex me. If a pivot table IS the way to go, could someone talk me through it step by step? (*the wizard is just as confusing as doing it yourself I find) ....

## Lexicographic Index Number To Combination?

May 3, 2012

I want to convert a Lexicographic Index Number, better known as Combination Sequence Number (CSN) to a combination using an EXCEL formula.C(n, k) Lexicographic Index Numbers, where n is the total numbers drawn from, and k is the total numbers drawn.

I have a lookup table in cell M1:R56 which holds the correct data, that I am pretty sure about.

In cell G1 I have the Lexicographic Index Number I want converted to a combination.
In cell J2 I have the value 39 (n).
In cell I2 I have the value 5 (k).
In cell K2 I have the formula =COMBIN(\$J\$2,\$I2).

In cell A1 (the first number in the combination) I have the formula:

=IF(G1=0,"",\$J\$2-VLOOKUP(\$K\$2-G1,\$M\$1:\$R\$56,6))

In cell B1 (the second number in the combination) I have the formula:

=IF(G1=0,"",\$J\$2-VLOOKUP(\$K\$2-G1-(VLOOKUP(\$K\$2-G1,\$M\$1:\$R\$56,1)),\$N\$1:\$R\$56,5))

In cell C1 (the third number in the combination) I have the formula:

=IF(G1=0,"",\$J\$2-VLOOKUP(\$K\$2-G1-(VLOOKUP(\$K\$2-G1,\$M\$1:\$R\$56,1))-VLOOKUP(\$K\$2-G1-(VLOOKUP(\$K\$2-G1,\$M\$1:\$R\$56,1)),\$N\$1:\$R\$56,1),\$O\$1:\$R\$56,4))

In cell D1 (the fourth number in the combination) I have the formula:

=IF(G1=0,"",\$J\$2-VLOOKUP(\$K\$2-G1-(VLOOKUP(\$K\$2-G1,\$M\$1:\$R\$56,1))-VLOOKUP(\$K\$2-G1-(VLOOKUP(\$K\$2-G1,\$M\$1:\$R\$56,1)),\$N\$1:\$R\$56,1)-VLOOKUP(\$K\$2-G1-(VLOOKUP(\$K\$2-G1,\$M\$1:\$R\$56,1))-VLOOKUP(\$K\$2-G1-(VLOOKUP(\$K\$2-G1,\$M\$1:\$R\$56,1)),\$N\$1:\$R\$56,1),\$O\$1:\$R\$56,1),\$P\$1:\$R\$56,3))

In cell E1 (the fifth number in the combination) I have the formula:

=IF(G1=0,"",\$J\$2-(\$K\$2-G1-(VLOOKUP(\$K\$2-G1,\$M\$1:\$R\$56,1))-VLOOKUP(\$K\$2-G1-(VLOOKUP(\$K\$2-G1,\$M\$1:\$R\$56,1)),\$N\$1:\$R\$56,1)-VLOOKUP(\$K\$2-G1-(VLOOKUP(\$K\$2-G1,\$M\$1:\$R\$56,1))-VLOOKUP(\$K\$2-G1-(VLOOKUP(\$K\$2-G1,\$M\$1:\$R\$56,1)),\$N\$1:\$R\$56,1),\$O\$1:\$R\$56,1)-VLOOKUP(\$K\$2-G1-(VLOOKUP(\$K\$2-G1,\$M\$1:\$R\$56,1))-VLOOKUP(\$K\$2-G1-(VLOOKUP(\$K\$2-G1,\$M\$1:\$R\$56,1)),\$N\$1:\$R\$56,1)-VLOOKUP(\$K\$2-G1-(VLOOKUP(\$K\$2-G1,\$M\$1:\$R\$56,1))-VLOOKUP(\$K\$2-G1-(VLOOKUP(\$K\$2-G1,\$M\$1:\$R\$56,1)),\$N\$1:\$R\$56,1),\$O\$1:\$R\$56,1),\$P\$1:\$R\$56,1)))

This works for the vast majority, but gives an ERROR when numbers 35,36,37,38,39 are in the combination, but funny enough NOT all the time.Lexicographic Index Number 575757 which is the maximum combination gives ALL ERRORS.

## Is A Number Or A Digit

Jun 22, 2006

how you can determine if a cel value is a number or a digit

It is actually for a column to determine if it has a heading or not and acordingly y have to count the rows off that "current region" and put some values with a formula next to this column.

Y was testing an expression with this

msg = IIf(target.End(xlUp).Value = "X", "is this a LETTER", "is this a DIGIT")

## Sorting Rows With A Combination Of Text And Number?

Aug 3, 2013

I'm currently trying to make a sort macro that sorts a row of data that has a combination of numerical data and the text entry "N.A."

e.g.:

My field:
1
2
N.A
4
5
N.A
9

I want to sort the cells by descending value. But the result appears as:

My field:
N.A
N.A
9
5
4
2
1

But I want to numbers to appear first and have the "N.A."s to be after the number, since I have about 100 columns and some rows have like 30 N.A., which is pretty bad for usability if all that appears in the first screen are "N.A."

EDIT: by the way by ascending the data is fine since it orders by smallest number to largest and THEN the "N.A."

## Find Number Combination In A Group Of Cells

Oct 28, 2011

I'm looking for another excel game changer (for the work I do anyway).

I have a dollar amount, and I want to know if any combination of dollar amounts in a particular range of cells will equal that dollar amount. Is this possible in Excel?

Example: I have 20 different dollar amounts in a column. I want to know what combination of those 20 different dollar amounts, if any, will equal \$257.97. The dollar amount I'm looking for and the numbers in the range will change with each use. I'm hoping for a formula, but VBA will work too as I could just make a template and copy / paste the numbers in.

## Add Specific Number In A Digit?

Jun 9, 2014

## Change Last Digit Of A Number To 5 Or 9

Jun 26, 2009

The last digit of a number (can be any demonination but always an integer). I know that you can check the last digit of a number with =RIGHT(A1,1) but I would like to check whether the last digit in number is 1,2,3,4,5 and if so change the whole number to a number ending in 5. If the original number ends in 0,9,8,7,6 then I want it to be changed to end in 9. Is this possible and if so is there an excel function that I could use??
e.g. 143 -> 145
e.g. 1037 -> 1039

## Add/Sum Each Digit In Long Number

Oct 17, 2006

I have a cell with a number which is a result of several previous sums. It's a number with 8 to 11 digits. For example: 878567663.

I need to add each digit of the number, and then add again the result until I end up with a single digit. In the above example it'd be (8+7+8+5+6+7+6+6+3=56), then (5+6=11), then (1+1=2) and put the end result (2) in a cell

My main doubt is that I don't know how to use a simple "do while" type structure in Excel to achieve the above.

Questions:

1.) How do I create a formula to do that?. I have seen solutions in this board that let me add each digit but that's it... I need to "reduce" it until only one digit is left...

2.) What about if the lenght of the number is not always the same (fe. in one cell is 8, in another is 11, the next one is again 8...)?

## Find And Replace A Specific Letter/number Combination

Jul 9, 2008

I have a column of references I wish to standardize. Contained within a general text description there is also an order-specific reference number, which is not relevant for my purposes. I wish to find all of these numbers and replace them with nothing (i.e. retain the rest of the description).

The reference numbers are always in the format "P#####/##". Unfortunately these references are in the middle of the text field, not at the start or end, so I can't use a LEFT or RIGHT formula to delete them.

Once these reference numbers have been deleted I will then be able to filter for unique records only. When I do this at the moment the filtering has no effect due to these specific reference numbers.

## Space After Every 4th Number In 16 Digit Character Set?

## Double Digit Number 03 Vs 3 With Formula

Jul 13, 2009

="autECLSession.autECLPS.SendKeys """&B4*100&""""

B4 is 3.00% and I need it to be 03 no %, 3.00%*100= 3 but I need anything less then 10 to be two digits still (1-9)

This would be the perfect end result:
autECLSession.autECLPS.SendKeys "03"

and for over 10

autECLSession.autECLPS.SendKeys "10"

## Return Last Digit In Cell As A Number

Feb 20, 2010

I am trying to get a formula to return the last digit from a number in a cell as a number.

If the cell (B3) contains a number such as 164 or 34 I want to return a value of 4 and have it be formated as a number.

I have tried =RIGHT(B3,1) and it returns a 4 but I cannot get another formula to recognize it as a number.
It shows up in the cell on the left side as text would and if I format it as a number nothing happens it is still on the left and the formula does not work.

## Searching A Cell For A 7 Digit Number?

## Converting 16 Digit Number Into Text?

Nov 25, 2011

I am using following formulae to convert 16 digit number to with validation that number is not exceeding 16 digits and should always start with "1" else it should give Error with 11 blank spaces

(IF(LEN(L2)+LEFT(L2)=17,TEXT(L2,"0000000000000000"),"ERROR"&REPT(" ",11))))

but when I input any number which has a value other than zero e.g. 1009510010000059 its returning result as 1009510010000050 I need validation also in the same formulae

20081110120000[0:GMT]

is there a way to convert many entries of dates and time entered in the above way into actual dates and times? is it as simple as making a custom format? if so, whats the syntax?

the entries appear to be the year(4 characters), the month (2 characters), the day of month (2 characters), and the time of day (6 characters, AM/PM)

i dont need the time, so the last part ("120000[0:GMT]") isn't necessary.

## Generate A Random 9 Digit Number

Jan 7, 2009

I have a spreadsheet with approx 11,000 rows and I would like to generate a unique 9 digit number for each line.

I know I could just put 100 000 000 and then increase that by one all the way down but I was wondering if there was any formula or code
