Since PowerShell automatically converts variables to other types to accommodate for operations the above loop does not stop at 1 like it would in other languages but loops for quite a while until the value is small enough to be considered 0. An explicit cast corrects this: |
|||
<lang powershell>$i = 1024 |
|||
while ($i -gt 0) { |
|||
$i |
|||
[int]$i /= 2 |
|||
}</lang> |
}</lang> |
