I just want to ask a question about creating a rounddown formula in excel.
The logic is to generate a rounddown numbers based on the range.
For example:
90-99 = 90
80-89 = 80
Numbers between 90 to 99 should be 90
And numbers between 80 - 89 should be 80
How can i create a formula for that?
The answer is in the question......
You can use ROUNDDOWN function, i.e.
=ROUNDOWN(A1,-1)
The -1 indicates rounding down to the previous multiple of 10, -2 would give 100, -3 1000 etc.
...or FLOOR function will also work
=FLOOR(A1,10)
Try this formula :
=A1-MOD(A1;10)
Here I have subtracted from the cell's value, the rest of the division of your cell's value with 10 (function modulo)

Consider the following sheet/table:
A B
1 90 71
2 40 25
3 60 16
4 110 13
5 87 82
I want to have a general formula in cell C1 that sums the greatest value in column A (which is 110), plus the sum of the other values in column B (which are 71, 25, 16 and 82). I would appreciate if the formula wasn't an array formula (as in requiring Ctrl + Shift + Enter). I don’t have Office 365, I have Excel 2019.
My attempt
Getting the greatest value in column A is easy, we use MAX(A1:A5).
So the formula I want in cell C1 should be something like:
=MAX(A1:A5) + SUM(array_of_values_to_be_summed)
Obtaining the values of the other rows in column B (what I called array_of_values_to_be_summed in the previous formula) is the hard part. I've read about using INDEX, MATCH, their combination, and obtaining arrays by using parenthesis and equal signs, and I've tried that, without success so far.
For example, I noticed that NOT((A1:A5 = MAX(A1:A5))) yields an array/list containing ones (or TRUEs) for the relative position of the rows to be summed, and containing a zero (or FALSE) for the relative position of the row to be omitted. Maybe this is useful, I couldn't find how.
Any ideas? Thanks.
Edit 1 (solution)
I managed to obtain what I wanted. I simply multiplied the array obtained with the NOT formula, by the range B1:B5. The final formula is:
=MAX(A1:A5) + SUM(NOT((A1:A5 = MAX(A1:A5))) * B1:B5)
Edit 2 (duplicate values)
I forgot to explain what the formula should do if there are duplicates in column A. In that case, the first term of my final formula (the term that has the MAX function) would be the one whose corresponding value in column B is smallest, and the value in column B of the other duplicates would be used in the second term (the one containing the SUM function).
For example, consider the following sheet/table:
A B
1 90 71
2 110 25
3 60 16
4 110 13
5 110 82
Based on the above table, the formula should yield 110 + (71 + 25 + 16 + 82) = 304.
Just to give context, the reason I want such a formula is because I’m writing a spreadsheet that automatically calculates the electric current rating of the short-circuit protective device of the feeder of a group of electric motors in a house or building or mall, as required by the article 430.62(A) of the US National Electrical Code. Column A is the current rating of the short-circuit protective device of the branch-circuit of each motors, and column B is the full-load current of each motor.
You can use this formula
=MAX(A1:A5)
+SUM(B1:B5)
-AGGREGATE(15,6,(B1:B5)/(A1:A5=MAX(A1:A5)),1)
Based on #Anupam Chand's hint for max-value-duplicates there could also be min-value-duplicates in column B for corresponding max-value-duplicates in column A. :) This formula would account for that
=SUM(B1:B5)
+(MAX(A1:A5)-AGGREGATE(15,6,(B1:B5)/(A1:A5=MAX(A1:A5)),1))
*SUMPRODUCT((A1:A5=MAX(A1:A5))*(B1:B5=AGGREGATE(15,6,(B1:B5)/(A1:A5=MAX(A1:A5)),1)))
Or with #Anupam Chand's shorter and better readable and overall better style :)
=SUM(B1:B5)
+(MAX(A1:A5)-MINIFS(B1:B5,A1:A5,MAX(A1:A5)))
*COUNTIFS(A1:A5,MAX(A1:A5),B1:B5,MINIFS(B1:B5,A1:A5,MAX(A1:A5)))
The explanation works for bot solutions:
The SUM-part just sums the whole list.
The second line gets the max-value for column A and the corresponding min-value of column B for the max-values in column A and adds or subtracts it respectively.
The third line counts, how many times the corresponding min-value for the max-value occurs and multiplies it with the second line.
Can you try this ?
=MAX(A1:A5)+SUM(B1:B5)-MINIFS(B1:B5,A1:A5,MAX(A1:A5))
What we're doing is adding the max of A to all rows of B and then subtracting the min value of B where A is the max.
If you have Excel 365 you can use the following LET-Formula
=LET(A,A1:A5,
B,B1:B5,
MaxA,MAX(A),
MinBExclude, MINIFS(B,A,MaxA),
sumB1,SUMPRODUCT(B*(A=MaxA)*(B<>MinBExclude)),
sumB2,SUMPRODUCT(B*(A<>MaxA)),
MaxA +sumB1+sumB2
A and B are shortcuts for the two ranges
MaxA returns the max value for A (110)
MinBExclude filters the values of column B by the MaxA-value (25, 13, 82) and returns the min-value of the filtered result (13)
sumB1 returns the sum of the other MaxA values from column B (26 + 82)
sumB2 returns the sum of the values from B where value in A <> MaxA (71 + 60)
and finally the result is returned
If you don't have Excel 365 you can add helper columns for MaxA, MinBExclude, sumB1 and sumB2 and the final result
I have a few hundred rows of data, and each has a number between 1 and 200, and I'd like to put them in categories of 1-5 depending on where that number is.
The categories look like this:
Zones Min Max
1 0 35
2 35 60
3 60 85
4 85 110
5 110 200
I want to assign it a Zone if it is greater than the Min, but less than the Max.
I have 2 formulas I've been working with to solve it. One is a nested IF AND statement:
=IF(A1<=35,1,IF(AND(A1<=60,A1>35),2,IF(AND(A1<=85,A1>60),3,IF(AND(A1<=110,A1>85),4,IF(AND(A1<=200,A1>110),2,"TOO BIG")))))
The 2nd formula attempts to use a SUMPRODUCT function:
=INDEX($C$2:$C$6,SUMPRODUCT(--(A1<=$E$2:$E$6),-- (A1>$D2:$D$6),ROW($2:$6)))
Rather than have to continue to adjust the numeric values manually, I set them as absolutes, which is why this formula is slightly different. The E column is the Max value set, and the D is the Min value set.
Any help would be appreciated!
Use this:
=MATCH(A1,{0,35,60,85,110})
Another way is to use VLOOKUP and you just need to set the min number:
=VLOOKUP(D2,$A$2:$B$6,2,1)
The key is the 4th parameter needs to set to 1 which means TRUE. It will find the closest value and return the zone for you.
But noticed that you have overlaps like 35 or 60 etc. that you will need to adjust your value column.
I have big amount of data (60k rows) in Excel that is similar to this:
Temperature Humidity Date
20.1 68 22-dec-14
20.3 67 22-dec-14
20.4 65 22-dec-14
20.0 64 23-dec-14
20.5 64 23-dec-14
20.9 65 24-dec-14
21.4 64 24-dec-14
23.4 64 25-dec-14
23.8 65 25-dec-14
23.9 64 25-dec-14
18.4 64 25-dec-14
I created new columns outside this table that contains the individual dates and I want to extract the MAX, MIN and possibly the AVERAGE of that date
DATE MIN MAX AVG
22/Dez/14
23/Dez/14
24/Dez/14
25/Dez/14
I tried but I can't seem to find a way for Excel to work for me. Could you help me?
I suggest you try a PivotTable:
Suppose column A contains the dates, and column B the values. I've allowed 6 rows in each; extend as necessary.
Consider a sample date in $D$1. The formulas you need are:
MIN: =MIN(IF(D1=A1:A6,B1:B6,MAX(B1:B6))). (You need to enter this as an array formula).
MAX: =MAX(IF(D1=A1:A6,B1:B6,MIN(B1:B6))). (You need to enter this as an array formula).
Use AVERAGEIF out of the box.
Remember that you need to press Ctrl + Shift + Return to enter an array formula. Then it's a simple case of copying that formula downwards.
They return the minimum or maximum value of the entire sample if a given date is not present in the set, which might not be desirable. You could adjust this behaviour with a containing IF.
You can take care of the pseudo-MIN/MAX with the AGGREGATE¹ function using the 14 (LARGE) and 15 (SMALL) sub-functions together with the 6 (ignore errors) option and the AVERAGEIF function can take care of the rest.
The standard formulas in F2:H2 are,
=AGGREGATE(15, 6, ($A$2:$A$60000)/($C$2:$C$60000=$E2), 1)
=AGGREGATE(14, 6, ($A$2:$A$60000)/($C$2:$C$60000=$E2), 1)
=AVERAGEIF($C$2:$C$60000, $E2, $A$2:$A$60000)
Fill down as necessary. An advantage of this method is that you can get the second, third, etc smallest or largest simply by raising the 1 (k ordinal) number at the right end of the AGGREGATE formula.
¹ The AGGREGATE function was introduced with Excel 2010. It is not available in earlier versions.
I can't seem to figure out a formula in excel for rounding up or down numbers to end in either 49 or 99.
What I'm looking to do
$824 should round down to $799; $825 should round up to $849; $874 should round up to $899; $873 should round down to $849
The number should round up or down to whichever number it is closest to.
Since it's always 49 or 99 you can use MROUND like this:
=MROUND(A4,50)-1
If you have a reasonably small range and you want other unique values that are not multiples of each other you can use a build-in lookup function like this (replace 'A1' with your value or cell address):
=LOOKUP(A1, {0,575,625,675,725,775,825,875,900}, {"Too Low",599,649,699,749,799,849,899,"Over"})
The lookup function allows you to do odd rounding such as your referring to by rounding 874 up instead of down. Alter the equation like this for this offset.
=LOOKUP(A1, {0,574,625,674,725,774,825,874,900}, {"Too Low",599,649,699,749,799,849,899,"Over"})
=ROUND(A1/50,0)*50-1
Source: http://www.mrexcel.com/forum/excel-questions/24527-round-nearest-50-a.html
So essentially, just round to the nearest 50 then subtract 1.
I agree that rounding of 874 to 899 seems strange. However, if this is not a mistake and can be reasoned, for example, by desire to choose 99 in the case of a tie-break, then here is the solotion:
=IF(ABS(MROUND(A1;100)-1-A1)<=ABS(MROUND(A1;50)-1-A1);MROUND(A1;100)-1;MROUND(A1;50)-1)
Output:
824 799
825 849
873 849
874 899
An Excel table consists of two columns (e.g., A1:B5):
0 10
1 20
3 30
2 20
1 59
I need to get the minimal value in column B for which the corresponding value in column A is greater than zero. In the above example it should be 20.
I tried using various combinations of INDEX(), MIN(), IF(), ROW(), array formulas, etc. - but I just can't figure out how to do it. :-( Any help would be appreciated.
Grsm almost had it
if you enter the following formula in C1 as an array (Ctrl+Shift+End)
=MIN(IF(A1:A5>0,B1:B5))
That should do the trick.
I think you have to make an extra column..
A B C D
0 10 false 20
1 20 20
3 30 30
2 40 40
1 50 50
column C : =IF(A1>0;B1)
cell D1: =MIN(C1:C5)
You need to do it in 2 stages
First use the MIN function to find the minimum
Then take that answer and use the LOOKUP function to select the row and column that you need.
Check the "Minimum And Maximum Values In A Range" example in http://www.cpearson.com/Excel/excelF.htm (you can download the same as well from the same section)

This is not identical, but very similar: Excel VBA - Find minimum of list of values?
