Powershell: Get object value to int array -

i'm new powershell

can please explain simple way copy values object basic integer array without copying original object.

sorry if confusing, mean want capture object values , put them in integer array can simple arithmetic on values

for example

$computercpu = get-wmiobject win32_processor -computer "mycomputer" | `     select-object {$_.loadpercentage}

on windows server 2008 vm @ work returns 2 values

i want average tried

$average = ($computercpu[0] + $computercpu[1]) / 2

this cannot work values not of type int.

i tried casting values

$average = ([int]$computercpu[0] + [int]$computercpu[1]) / 2

but results in cannot convert error.

i know problem great if explain fundamental solution run problem lot , know there must defined solution or way avoid entirely.

thanks.

ps: if possible please don't provide alternative solution, want know how objects values integer array perform arithmetic on values.

thanks.

in addition ebgreen's answer, use -expandproperty parameter of select-object:

$computercpu = get-wmiobject win32_processor -computer "mycomputer" |     select-object -expandproperty loadpercentage

the rest of code work then.

Look
