PowerTip: Use PowerShell to Round to Specific Decimal Place
Summary: Use Windows PowerShell to round numbers to a specific decimal place.
How can I use Windows PowerShell to round a number to a specific number of decimal places, and
continue to have a number instead of converting it to a string.
Use the Round static method from the System.Math class. By default, it does not display decimal places,
but you can easily change that behavior. The following code illustrates this procedure:
PS C:\> $a = 111.2226
PS C:\> [math]::Round($a)
PS C:\> [math]::Round($a,2)
PS C:\> [math]::Round($a,3)
