Answer 1

If you are using string variables you can format the string directly using a : then specify the format (e.g. N0, P2, etc).

decimal Number = 2000.55512016465m;
$"{Number:N}" #Outputs 2,000.55512016465

You can also specify the number of decimal places to show by adding a number to the end like

$"{Number:N1}" #Outputs 2,000.5
$"{Number:N2}" #Outputs 2,000.55
$"{Number:N3}" #Outputs 2,000.555
$"{Number:N4}" #Outputs 2,000.5551
