Summary: Use Windows PowerShell to round numbers to a specific decimal place.

Hey, Scripting Guy! Question  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.

Hey, Scripting Guy! Answer  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)

111

PS C:\> [math]::Round($a,2)

111.22

PS C:\> [math]::Round($a,3)

111.223
