How to return just one value in Powershell command?

Question

I have a Powershell command (which checks % CPU usage of a process) that returns me 2 values (Instance name + CPU%). I want to return just ONE value (CPU%). What should I add to this script to do that? Example below:

$Processname = "slack"
$CpuCores = (Get-WMIObject Win32_ComputerSystem).NumberOfLogicalProcessors
$Samples = (Get-Counter “\Process($Processname)\% Processor Time”).CounterSamples
$Samples | Select `
InstanceName,
@{Name=”CPU %”;Expression={[Decimal]::Round(($_.CookedValue / $CpuCores), 2)}}

The return value is:

InstanceName CPU %
------------ -----
slack            0

I want only the 0.

Try this-

$Processname = "slack"
$CpuCores = (Get-WMIObject Win32_ComputerSystem).NumberOfLogicalProcessors
$Samples = (Get-Counter “\Process($Processname)\% Processor Time”).CounterSamples
($Samples | Select InstanceName, @{Name=”CPU”;Expression={[Decimal]::Round(($_.CookedValue / $CpuCores), 2)}}).CPU

I would first expand the CookedValue property (using ExpandProperty, the general way to just return one value from a PowerShell object) and then make the calculation:

[Decimal]::Round((($Samples | Select -Expand CookedValue) / $CpuCores), 2)
