.NET Framework formatting

Format Numbers

$a = 348 

"{0:N2}" -f $a # Numeric to 2 decimal places = 348.00
"{0:D8}" -f $a # Decimal 8 places = 00000348
"{0:C2}" -f $a # Currency to two places = €348.00
"{0:P0}" -f $a # Percentage x 100 = 34,800 %
"{0:X0}" -f $a # Hex = 15C


# First number represents the index number of the item to be formatted.
# In this example we take teh second number in the array $a

$a=19385790464, 6786868768
"{1:N0}" -f $a

I seen PowerShell MVP Trevor Sullivan use this weird code in a demo and it had me intrigued. I had to find how it worked

"{0:N2}" -f $a

yes!
