Finding the minimum and maximum values

Posted by: | November 5, 2018 Comments Off on Finding the minimum and maximum values |

Finding the minimum and maximum values in a set of numbers is ridiculously easy with PowerShell.

I’ve created a function in line with the other techniques I’ve shown but in reality could be be done equally well as a single line of code:

function get-minmax {
param (

$mm = $iarray | Measure-Object -Minimum -Maximum

New-Object -TypeName PSobject -Property @{
Minimum = $mm.Minimum
Maximum = $mm.Maximum


Just pipe the array into Measure-Object and use the –Minimum and –Maximum parameters as shown. I created an output object for easier handling if you want to do anything else to the array.


You can also get the sum and average of the array with Measure-Object. PowerShell v6.1 adds the Standard Deviation and an –Allstats parameter so you don’t need to specify each individual option:

PS> $iarray = 1,2,3,4,23,5,6,7,8,9,10,23,11,12,13,7,14,15,16,17,18,20,21,22,11,23,24,25
PS> $iarray | Measure-Object -AllStats

Count : 28
Average : 13.2142857142857
Sum : 370
Maximum : 25
Minimum : 1
StandardDeviation : 7.46030057411125
