If you really must round them, there are already very good suggestions here (largest remainder, least relative error, and so on). doesn't work on Ubuntu 20.04 LTS with WSL? what must be minimized. Note that, contrary to your comment on @DStanley 's answer, in your answer 9.596008% was rounded to 9% which is more than a 0.5% difference. if there are way too many fractions ending in .9 say 9 values of 9.9% and one value of 10.9 there one value which will end up as 9%, 8 as 10% and one as 11%. Here's a simpler Python implementation of @varun-vohra answer: For those having the percentages in a pandas Series, here is my implemantation of the Largest remainder method (as in Varun Vohra's answer), where you can even select the decimals to which you want to round. QED. Select all the cells in the table of rounded numbers (i.e., the right-most table in the example below), and check that they add up to 100%. The question embodies a contradiction in terms. I think the following will achieve what you are after, One last thing, I ran the function using the numbers originally given in the question to compare to the desired output, This was different to what the question wanted => [ 48, 29, 14, 9].

For reference, the equivalent formula with the IF function looks like this: If the result of B5/C5 is greater than 1, return 1. Using @vvohra87's answer will make it independent of order and make sure the numbers with the highest remainders are rounded up, Correct me if I am wrong, but isn't this an implementation of the Algorithm proposed by my answer? The cost (in a binary integer programming sense) of doing so is less for the round up than the round down, because the round down requires we move that value a larger distance. You can mess around with the Error Alert tab to explain to other users why the sheet is yelling at them when the four cells add up to more than 100%, it's a nice touch, but not necessary. 3.03% B.

Follow these easy steps to disable AdBlock, Follow these easy steps to disable AdBlock Plus, Follow these easy steps to disable uBlock Origin, Follow these easy steps to disable uBlock. You can use the MAX function in a similar way to guarantee a minimum value. Wow. that's pretty much what I had in mind, with the difference that the error should be measured relative to the value (rounding 9.8 to 10 is a bigger error than rounding from 19.8 to 20). I once wrote an unround tool, to find the minimal perturbation to a set of numbers to match a goal. This is a very simple algorithm that consists of: Rounding all values down to the nearest integer value; How to deal with the sum of rounded percentage not being 100? @DStanley actually, barring a set where all numbers are shy of 0.5, you can. Now there's a clear winner. =ROUND (A1/$A$5,2). "Carry the remainder" from one row to the next. this could be very troublesome when you have a big array of zero-like number like [40, .5, .5 , , .5]. You can see the difference between this and blindly rounding each value, in the third value above. This is all fine but the difference between 12.08 and 11.61 is 0.47 so in my case to have those numbers both rounded to 12 is not ideal. [Refund Paid $$$] * rsQry!

I'd normally solve the general problem in MATLAB, here using bintprog, a binary integer programming tool, but there are only a few choices to be tested, so it is easy enough with simple loops to test out each of the 16 alternatives. 3, 4, 3). Ceil the 3 numbers with highest fractions and floor the rest. In the above formula B2:B15 is the list of cells which contain the specific text you want to calculate the percentage; 2. gave me a ground base to start with..

If I use parseInt(), I end up with a total of 97%. IF and AND using in order to calculate quantities. Nice! Similarly, 50 + 60 will NEVER be 100. The well-voted answer by Varun Vohra minimizes the sum of the absolute errors, and it's very simple to implement. Peano Axioms have models other than the natural numbers, why is this ok? Choose Percentage and select OK . Discharges through slit zapped LEDs. so [98.88, .56, .56] becomes [99, 0, 1]. Of course, if there were 20 terms, the search space will be of size 2^20 = 1048576. Probably the "best" way to do this (quoted since "best" is a subjective term) is to keep a running (non-integral) tally of where you are, and round that value. it's modern Js and doesn't need any library to use.
