Finding the mode of a set of numbers.

Hi everyone, I've got a set of numbers and i'm trying to find an algorithm that allows me to extract the mode (the number that appears more times in the set) from it, but i really can't find a way.

And what if i want to add a tollerance to the algorithm? what i mean is:

in a set like:

1.00

2.00

2.10

3.01

3.04

4.95

5.00

5.01

5.02

5.09

6.01

7.00

7.50

The mode is 2.00 because that's the most frequent value, but adding a sort of tollerance like 0,1 (e.g.) the mode changes to circa 5, bacause accepted values are 4.95, 5.00, 5.00, 5.01, 5.02, 5.09.

I know that this can be a difficult question, but there is someone of good will out there? Thanks a lot:)

Never heard of the term "mode" being used that way.

Mode, Median, and Mean are the three typical statistical measures of a set. There's nothing in GH to compute the median or mode directly but there are of course many ways of doing it yourself.

In addition to your excellent solution, here's a geometric approach which uses the [Point Groups] component. It has full control over the tolerance and returns the average value of all values that were within tolerance of each other.
