Why do integers in PowerShell compare by digits?

Question

My code tells you whether your guessed number is higher or lower than a randomly generated number, but it seems to only compare the first digits of the number when one of th

Never use a variable with the same name as an automatic variable: $input is an automatic variable.

See this code, where I pipe the value read from host (and don't use the $input variable):

[int]$GeneratedNum = Get-Random -min 1 -max 101
Write-Debug $GeneratedNum
$isQuitting = $false
Do{
    Read-Host "Take a new guess!" | %{

        if($_ -as [int] -gt 0){
            If($_ -lt $GeneratedNum){Write-Output "Too Low"}
            If($_ -gt $GeneratedNum){Write-Output "Too High"}
            If($_ -eq $GeneratedNum){Write-Output "Good Job!"; $isQuitting = $true}
        }
    }

} Until($isQuitting -eq $true)

Important to notice that my code treats correctly wrong inputs (non numeric characters) like w or like strings (qwerty), which make the other proposals to fail.

I make use of the fact that you generate integers always greater than 0.
