Round to Specific Decimal Place not working

Surya2023 

That suggests the locale within your PowerShell session isn't what you expect it to be.

You can check the setting via either of the following commands and then cross-reference the returned codes with the default separator for that language. You'll probably find it's the comma rather than the period.

# Example 1
$Host.CurrentCulture;

# Example 2
Get-WinUserLanguageList;

Edited to add information:

Turns out I just learnt the PowerShell variable actually stores the exact result I was suggesting checking.

# List the current decimal place separator.
$Host.CurrentCulture.NumberFormat.CurrencyDecimalSeparator;
